85F drop to 75f at night
thats for days 15-50....
days 1-14 you want 73-day 73-night, reduces strech alot.(yes even with co2!)
then... 15-50 you crank it up... for myself i do 15-21 @ 78-80-day and 70-night...
then 85 solid untill 45-50
when i got back down to 70-70 try and purple things up a bit.
if your not doing 73-73 first 2 weeks they'll strech alot more and give fluffier bud.
yes im using co2.
Yes he has good grows,but that doesnt mean he's correct at everything.I have to disagree completely having flowered with co2 for several years trying all sorts of different techniques.During the first few weeks of 12/12 the plants need light nitrogen and co2 and the more the better,that is when the most furious veg growth occurs and when the enrichment is really useful.I keep my canopy at around 85 F using a lazer thermometer.After day 45 or 50 on a 60-70 day strain I'll decrease the temps to 75-80 degrees.I find genetics to be the deciding factor on fluffyness of flowers or plant stretchEDIT A good question that I've always wondered is whether you want actual plant canopy temps or ambient temps.Since using a lazer thermometer I've realized it can be 5 degrees different easily.Normally the plants are a bit cooler than the surrounding walls especially after hydrating them.My p[lant canopy may read 85F while the wall inches away may read 90F.Its a conundrum..
Wouldn't it be useless using co2 enrichment with temps at 73. ive read that if your temps aren't higher than 80 the plant doesn't use the extra co2 your giving it.
just look back at digitalhippy's successes. i'd do what he says......
Agree, doesn't make much sense keeping temps low first few weeks of flowering since they're still in veg mode and while in veg mode, they can utilize tons of CO2.
If anything, CO2 can be kept lower near the end of flowering cycle.
As for the OP question, it's strain-dependent. Mine floats between 83-88 light cycle. Most of my strains can handle the heat, but I had one particular strain that could not handle the heat in a CO2 environment with high temps. It stretched, grew huge fan leaves, typical heat stress results.
80-85 is what I would like, but not really practical during summer.
