looks like N deficiancy to me with the leaves yellowing on the lower leaves first. also i can see yellowing in between the veins of the leaf, thats another indication. give it some extra N + Mg
i cant afford to run more lights might be better to say? im still looking to get a good answer to what is better for vegetative growth. 400w HPS or 400w CFL of mixed spectras?
i already have all the CFL i need. what i need to know is if it would benfit my grow area if i replaced my 400w HPS with 400w of cfl lights. would a 400w MH cover a 4x4 area efficiently?
Hey guys! my veg area is a 4x4 tent and im currently using a 400w HPS to cover it. i cant reaqlly afford to throw in more lights but i would like a better spectra then the HPS gives..
Would i be able to cover this area efficiently using 400w of cfl insted of HPS or would i not get enough lumens...
600w is definitely NOT overkill in 1.2x1.2x2.0m!! its actually a bit on the low side.. 800w is perfects. 1000w also works with good ventilation. anyways 600w = 416w per m2 = not bad and not overkill. btw 4x4 and 1.2m is about the same...
I have used up to 1000w per m2 with great success. if you...
ive heard somewhere that you dont need extra co2 unless you are growing quite big? is this not correct?
really cant see the point of co2 in such a small area :P. maybe im misinformed :)
Mi5 from short stuff. winner in yield and potency. theres some nice reviews around, some guy even pulled 3.7oz from 1 plant.. auto assassin is another great strain from short stuff
