my ec pen is driving me crazy

Bottom one is to drain water out, top one I don't know.

Ballasts produce a lot of heat. Best is to mount them outside the grow space with this kind of heat issues.

Some reflector designs, the bulb will heat up the reflector so much it radiates heat into the room.

Yes I have my ballasts in another room and yes the reflector is very very hot . It is melting the yellow plastic on their

I may have to buy cool tubes . My heat is now 27.7 and 25.6 bottom of room being hot test :/

Will the seedlings stretch a lot under these lights I am running 100th atm half the lights I want to run

Okay I am going to have to get 4 cooltubes to pull out the heat from them but my fan is 10 inch and the biggest cool tube is 8 inch so can any one help me on how to connect this or is their a connection available to buy ? Thank u

I wouldn't worry about 28 degrees C too much. Its not going to be that all year round.

That said if you wana set up cooltubes to that set up then get a couple of Y splitters, 8" if your getting 8" cooltubes.
You should be able to get 10" split to 2x 8" Y piece. Then rig up 8" duct to each cooltubes so you have two lots of cooltube in parallel line. Then either a filter at the end of each set of cooltubes or another Y splitter to a big filter.( If your running filters)

I will draw a diagram when I get home from work if its needed.

AC and a vented room will never work unless you're running multiple times the BTU you actually need. All you're doing is sucking the cold air out. An AC is designed to run in a sealed area. It'll never bring the temperature down the way you have it. Those single hose mobile ACs suck. The good portable ACs have dual hoses so they aren't sucking out cold room air to cool themselves.

Stop venting the room and let the AC do its job and bring the temps down.

With all the posts you've made, I think you need to reconsider what you're doing. Sounds like youre going too big for your experience level. Scale back, get some seat time under your belt, then go bigger.

If I use my 2500m3 box fan to vent and attatch my lights when I put them in 8inch cooltubes will the ac work ok then ? As no air from the room will be vented . Thank u for ur advice

Thanks if I vent the cooltubes with my outake fan will the ac come into play . And I will run co2. I do mean if I vent the cooltubes only and have the end of the fan duct bringing in outside air through the tubes and out of the room or do I have the vent in the room -cooltubes-fan-then out

Alls I need to tackle is the heat , everything else I can manage although yes I have made a good few posts on things I need to double check etc. I quiet easily made 36 ounces from the first grow of ten pots in less than half the space I have now . Now I will go for 16 pots with more experience and only one extra 600hps but that is what is killing me along with the outside weather heat . I hope cooltubes help . I only need to be around 26oc im at 28/29 atm

It'll work better.

Outside room>duct work>cool tubes>ductwork>outside room>exhaust fan. You could mount the exhaust fan in the room then run duct work out if you want to keep it all in one room. As long as there are no other vents, other than the AC exhaust, it should cool the room some. I don't think I'd run CO2 with that type of AC, it's going to suck it out.

Any cooled hood will help. My tents run up around those temps, it's not ideal, but it's not the end of the world. Keeping the air moving helps.

Are you saying I should run the duct from another room into the cool tubes and back out the grow room into the other room where it started

Yes, the ventilation for the lights should be its own separate circuit independent of the rooms ventilation/cooling . If you can pull from one area and dump it to another, that'd be better as you won't be recirculating the hot air.

I'd run 2 intakes, 1 exhaust. Something like:

8" intake>flex duct>8"cooltube>8"cooltube>flex duct>
......................................................................................... >8"×8"×10" "Y"duct>10"fan>outside
8" intake>flex duct>8"cooltube>8"cooltube>flex duct>


Then close up any room vents, except for the AC exhaust, and see how it does.

4 plants per light x 4 lights x 4ozs ea(min. I'd hope) = 4 lbs. That's what I'd be shooting for at the low end, although I'm usually around 6ozs per plant growing 4 per 600, so that'd be closer to 6lbs, if you can control the environment.

wow I'm amazed . and thanks for the help, one last question ... my exaust is way way bigger than my intake , like 2500m3 big and 280cfm small can I still attatch these together at each end of the cooling /cooltubes /light cooling system .

 

[Dylanfurlong]

oh yeah and if I have a 2500m23 to pull from the lights what size intake should I get for the other end , again sorry for pestering and thank u

 

[Johnei]

Weedfreak's got you, his ideas and suggestions are sound.

(Holy expensive hard to find special order Batman, was that 10" to two 8"'s Y splitter ducting when I had to find one.)

That's 2500m3/hr? That's around 1470cfm. Just run passive intakes for the lights with that fan. I'm cooling 2 600s and a 1000 with a 440cfm and a 200cfm booster. If you think you need it, I'd mount the small fan inline, after the cooltubes but before the bigger fan, as a booster. I don't THINK the fans can be stacked one right in front of the other, but I'm not 100% on that. I remember reading there needs to be at least a short section of duct between them, but I can't recall why. I put about 2 feet of duct between my booster and main fan, at the end of my duct run.

 

[Johnei]

surging effect of different cfm fans too close pulsing motors out of sync, and even identical fans too close one would induce a too strong pull on the others motor making it or both run out of spec and lower life.. If I remember correctly, some shit like that.

yes 2500m3 / hour. so i should have the final end at a passive intake which is just basically a hole for frsh air to coeme in instead of the inline attatched to the hole, it sounds good only that my big 2500m3 fan is placed high and hole is low so it would have a big drop at end of duct .this fan is also a twin but have sealed one of the ports atm but if i unseal it i may not need a y split , just should need 2x 10'' to 8 '' connectors ?, yes the fan is 10'' on the pulling side and 12 on the pushing side , their is two ports as i mentioned on the pulling side to make it a twin
