CO2 burner with grow tent setup advice

2. Here are some data of my tent that controller read
temp min: 73.5 max: 82.4
RH: min: 42% max: 68%
co2: min 627-1092
I above data is without running burner.
since my plants showing sign of stress I cut co2 and its been two days already.
They are not looking well. so I decide to cut co2 till they recover. Also have all my other environment problem solve before running it again.

A. Im not totally understand how fuzzy logic work. I just know it usually for bottle injection. standard mode can avoid burner been turn on and off in short time. I heard 1500ppm should be enough anything over than that could hurt plants. Is that correct? I also see people maintain at 2000ppm? Why connect timer with fuzzy logic mode not standard mode?

B. In this idea is to pull the co2 up high below to the ceiling? vent point have to set low right? I don't under stand how this replacing O2. everything in and out of the tent but still in the room right?

C. in what range of ppm is safe for avoid them to be choke be too much co2?
When you talk about oxygen here. are you talking about oxygen that already in the room? cuz room is sealed. how can I raise oxygen level?


3. I though 60-70% RH its good for veg. I was worried too low on RH. I got RH in high 30% the other day. wouldn't that be too low?


4. I done super cropping before, didnt like that too much is plants fall down if don't tie up branches. Both LST and supper cropping look the same for me. Could you advice whats the differences? I think both would work for my setup. just looking for the best training method for my first sealed room grow.


This is my thread about plants problem. I thought about heat stress, but after I check temp on leaves maybe its not. its under 85 when running co2. 78 without co2. other time when I had heat stress I see edge curl up, but not this time. have more pics in that thread.

have to say this

good damn job.......most ppl would of did it the other way ( the old style )
this way was little more work but the effects of it pay off so much more as u just seen ........the fact u are sucking in from the floor and dumping into the tent

keep track of how offen u replace the tank of pro pain ........if i done the math right u should get 3 times the normal amount from it .....since it keeps cycling and dumping it back in

just know if i would of given u bad advice i would of paied so u were not out anything ........thanks for proving my design (i never had a burner to work with just mash buckets for shine ....byproduct of yeast eating sugar making alc is Co2 )

dont even mention that man. this is your credit and thanks for giving every idea for my setup.
I would have waste more money without your advice here.
right now I just need to adjust everything on point provide best grow environment for girls.
I should have running the room without plants for few days, then I can avoid them to be hurt...
but good thing is I guess they dont need co2 until they recover, which means I have time to correct everything.

1 plants under stress......B-52 is your buddy add 5 mls to the water u feed them to help them recover and get use to the new area ........the vitamino stuff not sure about it yet but i know the B-52 will cover u and help u out

2 fuzzy logic is simple it is rough math ........if the system reads a 1000 parts it is thinking it can be 960 to 1040 so it goes with the lower number and adds more ....hence why your rate was little over the 1500ppm like 1700 ppm .....this type can be run by a timers (the controller gets power to tell the burner to kick on or off for what the area is rated ) .......shut the controller off 1 hour before lights out so the oxygen lvls increase and turn it on 15 mins before the lights kick on so the CO2 lvl is at point when it comes on

3 the venting is cycling the Co2 .....as Co2 is a heavy gas u have the intake placed down low like that and it sucks it up and dumps in the tent....as the tent is not 100% sealed it leaks (but with u sucking it up and dumping it back in it counters the leaking) .....the Co2 is in that room u have the tent in (odds are a small leak room but nothing big) .....see u have the room cycling on it self (there is not air being moved in and out) ........so once the co2 gets to lvl the plants use it and change it to oxygen that lowers the CO2 lvls and the burner kicks on

4 co2 lvls outdoor u are looking about 150 200ppm ......inside 500-600.........safe 800 zone half of days amount so the oxygen is easily accessed

5 the higher the RH the more chance mold spores can attach and grow .....i live in a guy house so cleaning does not happen all that much to make sure nothing can wreck my plants i keep my area at 50% RH .........the mid point not to much not to little .....this allows me to have a tent in the room just for Drying the plants

6 do the pinch during the stretch part of the plant ........just 2 pinches( one east and west one north and south at the same spot) on the branch under the lowest bud site on the branch ......then hit it with 5 mls of b-52 for 2 weeks u will have a knot

the heat stress is from the IR heat ........u just need a fan blowing over them ( like u outside in the sun no wind the temps build up on your skin with a light breeze those temps are reduced ) ....a little 6 inch clip on fan that moves side to side

as for what i am seeing
1 nitrogen and or iron lacking
2 your air pumps.......u do have them sitting up HIGH.......rem your area has Co2 in it so if the 2 low u are adding Co2 to the water (co2 in the water lowers the lvls of oxygen in the water ).....so u need to have your air pumps in a area with high oxygen ......in the room that is a high point u can place it (other wise outside the room in a cool part of the house)

again B-52 5 mls per gallon
and some of this https://www.amazon.com/Liquinox-3032-Chelated-Solution-32-Ounce/dp/B0063PG40G

just a quick info for u

if u ever need to add something to the plant ....CHELATED is the key word u look for plus what u are missing .....it means it is done up so easily absorbed

1. Yes I decide to pick up b-52. do you use it only when having problem?
for Iron and Zinc Chelated can I use seaweed instead? In my other thread someone recommend Kelp and Maxcrop Seaweed.
Maxcrop Seaweed its easier for me to get instead of Iron Zinc Chelated you attach with link.
I also have some Iron chelated on hand. since anything I order wont arrive in two week I will add some in Res. to see how plants react.

2. I read the instruction, It say fuzzy mode can only use with compressed co2. Can not use with burner. Do you think Im ok using fuzzy mode with burner?

3. Do I need set air pump in Ebb system? I have pump in the Res pump water to the chiller and flow back to res. Isnt that make O2?

1 b-52 i use it all the time ........ my soil is mixed up differently so instead of using any grow feeds i use just B-52
b-52 is safe to use all the way up to the week before u cut her down

the chelated iron pills will work just crush them up and mix into a a quart jar with hot water to desolve it ....then throw in some ice cubes to cool the water down before u pour into the system
light green like that or a yellowing is from Nitrogen lack of or Iron lack of ........if u add it to the water and see no change with in 2-3 days check your waters PH make sure it is 5.8 5,9 zone so it is not lock out

2 i am not 100% sure ...........to cover u i would tell u to ask someone with a burner ( i used mash buckets my area can not handle the heat from a burner)

3 anything that the roots soak in water needs a Oxygen pump or something to add Oxygen to the water
oxygen in a hydro set up is a must ........other wise the roots drown when they get covered in water
yes ebb and flow needs something .......in the holding tank do u have a pump that keeps the waters cycling (like a fountain) ....that is like a waterfall effect and it adds oxygen into the system and keeps anything in the system from settling


ok water.....the colder the temp of water the more oxygen it can hold in it for hydro u are looking for 65/68 degree water for best oxygen and control of the micros around the roots
now if the water is warmer then that u can off set the oxygen decay in the water buy using a stronger pump moving more air into the system and use of nano pore stones ......do not let the water get above 75f other wise u can get root slime

(hit the store and but a gallon of juice drink it ......take the jug from it wash it out and fill it 3/4 way up and freeze it .........make sure the cap is on once it is 100% frozen .....when u look in on the water if u see it getting warm take the jug and put it in the holding tank to cool the water down for u ( with the cap on it u are only doing thermal transfer no water is mixing and diluting your feed)

1. Iron I have is powder one. Its for Aquaponics. After two days used plants still not looking good...
I bought a bottle of Grow More Seaweed Extract. Hope that would get them recover. B-52 is also on the way, but wont arrive untill two week. really cant wait that long.
I sea B-52 also contain seaweed. probably doer sort of same job, but B-52 have more micro in it?

2. I think I can use it with standard mode with timer on like you recommend. If I have exhaust in the room. I can also use that if that doesnt work for me.
but to bad I can not correct this right now. I want to add back co2 when plants recover.

3. Yes the pump for chiller is cycling the res. I also use hydroguard for safety. so this part I should be good ?

4.Without adding CO2, My tent Temp gets kind of high right now. 85F. Im worried about its too high right now.
and My Cobs panel should arrived Sat. or next Mon. Cant wait to swtich on, but in the mean time worried about if LED its gonna bring enough heat when adding co2.
man this really make me headache...I should have build a regular venting setup for a run than sealed up the room with CO2
Other grower in my plants problem thread recommend low 90's and high RH80-85% when running CO2.
Thats complete different than what I learned. I thought just slightly higher, and RH is required as same vent setup.

I wonder maybe its lack of air change in the room right now. cuz I cut CO2 as soon as I see plants having sign of stress.
Im making an exhaust for the room. Thinking running 15mins for every two hours to have air exchange.
Any suggestion on this?

1 b-52 .......crack a vit pill in half and smell it ........B-52 smells like that it is 1-0-4 rating ....... that is basicaly what B-52 is a quick form of N and K for the plant plus a load of vits to help the plant recover from stress (shortens the recovery time for the plant and also strengthen the plant ).......when u were a kid and mom gave u vit pills to make sure u got everything u need for the day as u were a picky eater .........make sense

2 if u want to use Co2 u can just keep the ppl to a lower setting like 800 1000 ........it would be like putting a sick person in a room pumped full of oxygen they will feel ittle better easier for them to breath

3 since the system is sitting low it is also trapping Co2 into the water
http://www.greners.com/i/pumps-irrigation/air-stone/micro-pore.html

this is the best air stone i have found .......they make tiny bubbles ......u want to single XL unit( it will sit in the bottom of a bucket perfectly ) ......it will fit 1/4 dia hose to it and a simple air pump
(if u do not like the unit i will pay u 30 bucks for it ) ........this stone will last u forever not a cheap on one that decays in the water (this is the stone that made my monster plant)

https://www.amazon.com/Hydrofarm-Air-Pump-Outlets-7-8L/dp/B002TCC46U
this pump .......on full power this pump will add 2 gallons of air to the water per min (complete over kill but it makes 100% sure oxygen lvls are good)
https://www.amazon.com/uxcell®-Aquarium-Airline-Connectors-Filters/dp/B0051SM6GW
this is for the T so u can put both lines from the pump into one feeding the stone

set the air pump up high so it is only cycling in Oxygen into the water

4 your in veggie right now .......so the temps high are not as bad as u think ......it is when u get into flowering and the plant is forming THC ( 80 degrades or higher makes THC degrade faster turning it into CBNs and other things .......it makes the smoke weaker)

if u want to cycle the air in the room u can
the easiest way to do this open up the doors .....the co2 will flow out looking for the lowest point it can go ......just have a fan to blow the air into the room and the co2 will come flooding out like it was invisible water ( as it is in a tent the light leak will not be a issue for u so that is the quickest simplest way to do it with out modifing anything or spending money ( just a fan placed in right place at the right angle with doors open)


Other grower in my plants problem thread recommend low 90's and high RH80-85% when running CO2.
insane .........those temps and lvls mold or fungi can attach to the bud and kill your whole crop in a matter of days with the right air movement in there
the only way i would advise to do that is u were in a 100% clean area with air scrubbers that are lvl 10 filters with UVc light ( to completely remove all spores from the air and kill them with UVC light)

anything over 60% rh is danager zone .........that is prime mold fungi zone they have enough moisture to live and grow ( if u get PM in your area the only way to get it out is to harvest your buds wash them in hydroperoxide let them dry and then bleach wash your whole area ( 25% bleach 75% water hand scrub all surface and then spray bleach water in the areas u can not clean to kill spores laying there)

3. Sorry I can not see the link. Do you think even I have pump cycle water and making water fall in res. also have res temp 68-69F Isnt that should have enough O2 in Res?

4. Now I let the tent open. and can get 78 inside of the tent. Hope I can have less temp different when using LED panel.

I already made that exhaust for the room while you replied this...haha
but I wonder have the door opened isnt cause A/C running all the time?

Yeah...I do more research on Co2 temp and RH. I dont see any mentioned RH should be that high...
Hope I can have everything under control never have PM on buds.
Regarding to UCV light to make clean area. Where would you recommend to the UVC light? beside filter?
Any model recommend?
If I keep RH around 50. Do you think I could possibly skip this?

Oh..and I got that Grow More Seaweed extract yesterday. Add some to res to see how plants react.
Also have B-52 on the way. Im going to put b-52 on my regular use too. Hope that stuff can letting plants tranplants or veg clones without shocking them too much.

You have a nice day

yah the pic for it does not come up greners has beening having issue
just pick the XL single one .....if u do not like it when it gets there i will buy it off u

the trouble i think u are having is the Co2 in the air is geting picked up by the water ......CO2 in the water the plants are having a hard time getting the oxygen they need
the rez where the water is cycling back in is low to the ground (the area where all the Co2 is collecting) your water is collecting the gas from the CO2 in the water when it folds the air into the water from where it pumps (waterfall effect)

i have never run RDWC with a burner i done DWCs with mash buckets .....i did have a issue when the air pump was low to the ground when i put in the mash bucket i set it up on top of the tent ( the air pump) and trouble stopped

http://www.ebay.com/itm/New-Commercial-Air-Purifier-DUST-SMOKE-ODOR-MOLD-remover-w-OZONE-GENERATOR-X/161843624730?_trksid=p2045573.c100034.m2102&_trkparms=aid=555012&algo=PW.MBE&ao=2&asc=20131003150253&meid=5cd33284ad874e5fb5b2bd1aedef7251&pid=100034&rk=2&rkt=8&mehot=ag&sd=111588137044

that is the new verison of the one i have ........hemp UVC ion ozone and active carbon
this is the filter i use where i live so ppl can not smell shit ......a 400cfm fan on it with a UVC light behight the filter so what passes over it gets nuked .........the part u need to rem is the Ozone it will counter Co2 (it is oxygen with a extra atom so it will attach to co2 and lose the atom ...turn the co2 into nothing) .....great for clean out smell

mold is always possible .......if u keep it at 50% less likely hood of trouble ....as for this thing it is up to u i usie it to clean my air as i smoke and i have ppl come over now and then need away of hiding the weed is growing smell

for your plants

1 make sure the Ph is 5.8 or 5.9 ( check this fact daily if it is off that those numbers u can get lock out for parts of the feed the plant needs )
that is normally always the trouble with a hydro system

if that is not the trouble

2 the B-52 will increase the amount of Nitrogen that should make the plant greener ( and help de stress it) ........if u add this in and see a pick up increase your grow feed by 10 mls( total 10mls not per gallon10 mls) and u should see even a better result in the end

3 i think part of the troubles is from the air lvls in the water ........your waterfall effect is grabbing alot of Co2 and that is being mixed into the water lowering the oxygen lvls in it (to fix that u need a air stone in the main mixing bucket ....where the waterfall is being made in the system) just place the stone in there and hook to a pump place the pump highin the room like above the co2 gen lvl high that will pull in more oxygen to the water forcing it not to take in so much Co2 .........u want the pump to be strong like 2 gallons a min ( 7.2 lpm) liters per min u need something 7 or 8 lpm range that will be 2 gallons of air per min tho the water

4 keep adding the rapid start to get the roots going .......that stuff is great it builds great roots

this is the filter i use where i live so ppl can not smell shit ......a 400cfm fan on it with a UVC light behight the filter so what passes over it gets nuked .........the part u need to rem is the Ozone it will counter Co2 (it is oxygen with a extra atom so it will attach to co2 and lose the atom ...turn the co2 into nothing) .....great for clean out smell

mold is always possible .......if u keep it at 50% less likely hood of trouble ....as for this thing it is up to u i usie it to clean my air as i smoke and i have ppl come over now and then need away of hiding the weed is growing smell

I think I will add some air stones pumping some O2 to res for sure.
I wonder does that pump need to be on 24/7? Can I just set a timer put it on like half hour before flood?
I never run CO2...I thought pump making water fall and temp at 68-69F should have enough O2 in it....

Thanks for the link. I will try if I can find some similar at local stores. Before that I have to keep the room clean.
Clean with bleach or something like that.

for your plants

1 make sure the Ph is 5.8 or 5.9 ( check this fact daily if it is off that those numbers u can get lock out for parts of the feed the plant needs )
that is normally always the trouble with a hydro system

if that is not the trouble

2 the B-52 will increase the amount of Nitrogen that should make the plant greener ( and help de stress it) ........if u add this in and see a pick up increase your grow feed by 10 mls( total 10mls not per gallon10 mls) and u should see even a better result in the end

3 i think part of the troubles is from the air lvls in the water ........your waterfall effect is grabbing alot of Co2 and that is being mixed into the water lowering the oxygen lvls in it (to fix that u need a air stone in the main mixing bucket ....where the waterfall is being made in the system) just place the stone in there and hook to a pump place the pump highin the room like above the co2 gen lvl high that will pull in more oxygen to the water forcing it not to take in so much Co2 .........u want the pump to be strong like 2 gallons a min ( 7.2 lpm) liters per min u need something 7 or 8 lpm range that will be 2 gallons of air per min tho the water

4 keep adding the rapid start to get the roots going .......that stuff is great it builds great roots

1. Yes I bring down PH to 5.8 everyday. When up to 6.2 after 24hrs. so Im doing this daily.

2. Got you bro. Hope they getting well before B-52 land. B-52 wont be here till next weekend. so Im hoping Seaweed extract would get rid of their stress first tho.
I also heard ppl recommend a product called Superthrive. Also Vitamin product contain kelp. Seems like its more concentrate and cheaper.
Moving nutes all the way here its expensive. so I always looking for powder product if possible. small bottle can cut some weight too.

3. I will add air stones in tonight. It shouldnt be too bad cuz I only have burner on for 1 day.

4. Oh no...I dont have Raipd start. B-52 its on the way...I might skip this one...do you think that would be ok?

Have a question for sealed room without exhaust, and not adding CO2. (Like end of two week or plants stress like I have right now)
Is plants gonna be ok without air exchange? this really make me confused.....

Now I have room exhaust running 15 mins every 1 hr. Will cut it when plants recover and put co2 back on.
Hopefully I dont need to use that until end of two week, isn't it?
By the end of two weeks. I need to connect with filter for smell right?

1 the room can be sealed and Co2 be added or it can be a exchange system ....has to be one or the other
to seal a plant off with nothing just AC for temp control u are just going to make the fluffy crystal weed ...whole thing maybe 2 and half oz of something i would not setl (when my experiments go like that i grind the plant up for joints

A if it is a sealed room u have no worries about smell
B if it is a exchange room u have to have something up with in the frist 2 weeks of life of the plant

the plant will have a smell to it .........as new to growing it took me 5 weeks before i could even breath tho my nose(this is veggie stage)

ok exhusting the room out unless the vent point is low u are only removing the oxygen in the room
(water and oil ....water being Co2 and oil be Oxygen) .......aslong as u have a intake point to let the pressure equal out other sie it is going to try to equal it by any means needed so that means sucking tho smaller opening (those smaller opening is bad as that is where the dust incest bodies and all that other stuff settles so a sudden back draft into a larger area will kick up spores and mold) ....so u want a clean air path at all times when u do any exchange


rooting is so important ..........what ever feed system u have should have some sort of rooting feed (hormones with some feed to trigger the plants to root) ...........the root mass is one of the most important things when u are growing ( the fact u are hydro lest u look in and judge what the plant has done).....but u need roots and those roots need those fine tendrils on them .....those are what feeds on the water and food u offer

rapid start is the best rooting i have found ....5 years of trying different things nothing has beaten it

the air stone runs 24/7 none stop for as long as a plant in is your system

as for the waterfall effect that might be true if u were not adding the C02 it is a heavy gas so the waterfall effect is right in that zone of 1600-2000 ppm I the 1500 ppm should be at bud lvl meaning the lower lvls are at a even higher rate

Good day,
It's pass more than a month.
It's about time to flip
But plants dont look 100% healthy to me
Leaves its kind of dry.
Co2 stay around 800-1200.
81F when lights on 72f lowest
RH 50-85
They are filling the tent pretty good even they don't look healthy. Want to make sure I don't messed up any plants.
Any advice would be appreciate
