minimum temperature?

How low can the air and water temp go before it hurts the plants? :confused:

I want my young'uns healthy!

actually, i should say "what is the optimum temperature?"

i think, and im not sure where i got this from, but there spose to be in the seventies..

keep temps in the 70's...rez in the high 60's...cold water produces more oxygen than warm water. humidity in the low 40's

hit the faq's man.

basically, and without looking up exact temps I think photosynthesis only occurs above 50f Degrees, and up to 90f.

LW, do you keep the RH around 40 even in veg???

No...I keep it natural because you want it more humid in veg room. I get such great photsynthesis that I just use the old...if they look great, then they are doing great, mentality. But really no. You want your humidity around 50-55% in veg and 40% in flower. Higher promotes possible fungus and rot.
good rules: keep your temps at 80f and humidity in low 50's% for veg
for flower keep temps around 70 and humidity at 40%...If possible keep your rez temps in the low 60's for more oxygen...Oh yeah, I almost forgot.
I subscribe to the theory that shorter veg photoperiods promote more females...OK. there I said it again. hope that answered your question. peace

What is a shorter veg period in your book? I know that you have talked about veging for 8 weeks, but with what your saying now, do you mean longer than 8 weeks? What is a good balance in your book?
In spite of all of my experiments I think that I may just do a 8 bucket set up under my 2K's here in a few months after I grow all of my current projects and am done trying to experiment with some strains. It seems like that NIC, or SD I can't remember was a killer yielder for you, how was the smoke? And do you think that you just got a awesome feno or what. Right now I am thinking about using WW or A highbred I have of a non purple feno type of PurpleLion crossed with some local stuff, some Grape fruit or some Skunk Special for my staple crops. Do you have any input or observations with any of these strains? With my disability I really want to dial in a couple strains which are heavy yielder's and about a 8 in the potency department so I can give my wife a break with all of my experimenting all of the time which she has to be my assistant for and the heavy yielding would help in case I shut down for long periods of time and didn't have any product.

:) :upsidedow :) :upsidedow :) weeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee e...roflmao

I was talking about 16/8...15/...14/10 photoperiods
veg 6-8 weeks from seed...8 for maximum harvest, and 2-3 weeks for clones. remember that the longer you veg, the longer a plant from seed will take to finish

I went thru the same thing...although I still experiment...I am more porduction of "goodies". WW(no intro's necessay, but hard to grow, tempermental...I like the skunk strain you chose. I am growing an AK-47 cross "fantasma"...It yielded me over 1/2lb...in a DWC 5g bucket...
the NYCD is humongous...I will show you all a pik...don't tell! lol

If you want pain meds, then get some afghani strain, and the NYCD is some of the most potent chitman...
here is a pik of NYCD:joint1: Enjoy this plant was grown with the formula I posted, and in a 5g bucket with 1 wally's 5' airstone:smokin:

p.s at least your old lady helps...lol
