OK,
now I'm annoyed. I just spent 45 mins replying to several of the 2 pages of questions waiting for me, hit POST and the RIU board threw an error and LOST THE FUCKING LOT.
If this happens again, I'm NOT going to bother re-writing all those answers. I simply have too many other things to do.
OK,
once more with feeling... pardon me if I'm brief.
Ahh,, everyone loves the tales of Stoney McDoper. Just wondering do you still prefer your cloning to be done in RW as in your sig. or haveyou moved to a different method? I never seem to have any luck with RW. So I've been using Rapid Rooters at about 80% rate and taking about 15-20 days, can you make a suggestion to speed this up and have a better rate of success. THanks again Al for all your knowledge
Cheers for the thanks.
If you have no luck with RW cubes, there's a high probability that you're keeping them too wet. RW is highly absorbent and it's very easy to overwater the material. Refer to my thread on cloning in RW in my signature for details. I have changed the process only slightly; I'm now using only plain water to pre-soak the cubes and water the clones, no H2O2, no pH correction. Works fine, 100% strikes in 10 days. Clonebox air temp is 26-27C, heat mat temp set to 30C.
Thanks Al B for the info... This is the (1) of few threads that hAS VERY useful info....
Back to where I left off on the ventilation question... Using cooltubes makes sense but what would you recommend for getting rid of the smell... The budget is LOW... I was looking into carbon filters... I am trying to figure pressure in the room... What size tubes and fans should be used?
Most cooltubes are 150mm dia. Use a good quality 150mm axial blower for the cooltubes, preferably a fan with ball bearings on the motor shaft. Carbon filters present a high static pressure load. You must use a centrifugal blower with carbon filters. You need to shift the volume of the room's airmass in about 3 mins. A 500 cu ft room needs a ~167CFM exhaust blower.
Al B whats your opinion on CMH vs HPS? I have an old bloombox and have been reading on CMH 400w and wondering if it would be worth trying.
CMH is kinda interesting but not really necessary. CMH does have a broader spectrum but cannabis doesn't need the blue end of the spectrum for flowering. In SoG, you're not vegging the plants to be flowered, so all the flowering area needs is HPS.
I've since revised the nute strength downward. 1000-1100ppm from go to whoa.
I'd like to know since I'm pretty much mirroring your setup to a tee (2 1000w setups, air cooled magnum xxxl hoods, flood tables with 40 gal res, 40 plants to a table, ect..). I'll be basically using Canna A/B aqua flowering and a few additives CANNA PK 13/14 and cal-mag (if needed). The other canna additives seem like a ripoff (one looks to be septic bacteria i.e CANNAZYM, and the other RHIZOTONIC seems kind of hype-ish).
Cannanym isn't compatible with H2O2, so that's out. Rhizotonic is hugely expensive & hugely stinky and I've never noticed a benefit from it. OK to skip it.
Also what PPMs do you recommend for light, medium, and heavy feeders? My current plant was to use cannas at 1400 ppm flush every 2 weeks and top off the res with tap every few days and ph correct if need be.
1000-1100 will do for just about any cannabis plant. Don't flush between tanks- that actually can cause problems; flushing will leach nutes out of the rootmass.
FYI tentative setup is (2) 1000w setups, 4 flood tables, 4 40 gal res, 40 plants a table, CO2 generator (got it on the low and will be running it during feeding every 90 mins for 4 mins), Dehumidifier, 4 air stones, and maybe a ductless AC setup if need be, also all the obvious ventilation (fans to air cool the hoods, another to bring fresh air to the room, and one to scrub the air).
Sounds good
Also some quick general questions what size is your dehumidifier (I was looking at 30 pints a day, but it's cheaper to buy a 70 pint a day unit my room is only 9x5x
?
What sized pumps do you use...I was looking at 250 gal a min or 360 gal a min (for each 40 gal res and table).
I don't recall the capacity of my dehumidifier at this instant, but I'll check later on & get back to you as time permits. Use the highest capacity dehumidifier your wallet allows. 70pt/day should do fine. Your target RH is around 30-50%, adjust the dehumidifier to suit. Use a peak-hold thermometer/hygrometer so you know the ranges.
P.S. thanks for the kick ass work. Your threads have been highly informative and well written. Thats a true rarity on web forums.
Cheers for that.
i like how you can tell me my plants cooked like you were inside my room watching them every day man. I dont care what you guys spend your money on but you honestly make yourself look ignorant when you refuse to recognize something that works i could link you to a bunch of LED grows
blah blah blah
Remember what I said about not wasting my time? Welcome to my ignore list. It's rare company- you're only the 2nd person I've put on ignore in 15 years of commenting on cannabis boards.
the reason people buy these is because there is no fucking mercury in them they are safer however they cost out the ass to not have to worry about, wow light nazi's in here next i bet you will tell me that CMH is complete bullshit too.
Rubbish. ALL fluoros have mercury in them and the lights advertised are nothing but plain old fluoros. It's a sucker ad for ordinary fluoros. You really don't know what you're talking about- time for you to be very, very quiet. A deserving addition to my ignore list.
hay al, have you ever thought about starting a class on growing, half of riu will be there no matter where it is. your name is golden. even if you put your name on plant food it will sell. just got done replacing the circuit panel for the whole house, now its time to play with some hydroton. thanks for eveything "DR. AL"
Thanks for your confidence & compliments. No, I've not considered running a class on growing, but I have briefly considered offering grow op help on a subscription basis. I haven't found the spare time to actually do that, though. Just far too busy.
My pots are 4.5" tall, so can I fill them with 3.5" of hydroton then have the 1.5" rockwool sticking out 1/2" over the pot so I can flood my table 3"? or does the entire rockwool cube have to be in the hydroton?
also since I'm using netpots how do I deal with light hitting the roots growing on the outter part of the pot? Not outside of the pot but the roots circling just inside on the edges.
Load the netpots to the top. Nest the 1.5" cube into the pellets so that the cube bottoms are 1/2" above the flood level. Don't worry about light hitting the roots through the netpot mesh. The plants will make roots elsewhere, where there's no light getting to them.
Mind you, you're going to get sick of lugging clay pellets around and you sure won't want to clean them for re-use. Give some serious thought to a sterile, disposable medium in plain old 175mm dia x 175mm tall round plastic pots. Netpots really aren't necessary. The drain holes in ordinary plastic pots do fine for admitting nute soln & draining as well.
I see what you mean now. Your saying you think I need to put the hydroton ON TOP of the rockwool too? That's what I thought too, but it seems like Al was saying you don't have to... I'm sure he'll will clear it up lol.
My table is 4'x4'x7" tall. I have no clue why they're only 4.5" tall lol. I just bought 6" netpots thinking they'd be 6" diameter & height.. Anyone know if net pots are usually this short or what the reason is? They're from 2 different places too and they were both that size.
No need for pellets on top of the RW cube. All we're looking for is to have the cubes 1/2" above the flood level. If the cubes are touching or below the flood level, the RW will saturate and kill the young plants before they have the oppty to get roots down into the pellets.
whuh i dont think al will be on rui long, his last post was 2008! he said he was just checking in but if each one teach one we will be ok. im on the same page as u 4x4x7 table 4x4 tent 1000w light, aircool hood, 7 inch square pots lol we are on our way
Oh, I'll be around for a few days, but answering questions on here is already clashing with my other work. I just don't have time to keep up with everything on my plate.
He was just here today answering questions. I hope he's not gone yet. I still have a few things to ask. lol
cool so it should NEVER get wet? I read somewhere like once a week or maybe month you should flush it or something.. I don't need to do that?
The RW cube should not be touching or below the flood level. Roots will seek the wet pellets. You may want to hand-water the pellets AROUND the cube for a few days immediately after planting in the pellets, but don't water the cube itself.
