Damn those are some nice lookin' plants !!
What are your ppm's coming out of veg ?
What were they before and after dilution ?
Don't leave out that info ! LOL
I just bought these beans bro. LMAO
So this is what's up, your tent is 6ft - 15" for buckets = 57 inches
How tall are your girls ? Let's say 12" and give 10" for hood height from top of tent to bottom of hood.
According to Nirvana, AK48 is mostly Indica w/ short height (2x stretch) and WW is medium height (2.5x stretch). Both go 8 - 10 weeks.
So AK48 at 12" X 2 = 24" and WW at 12" x 2.5 = 30" but lets say 36" for a stretchy pheno.
57" - 10" - 36" = 11 inches of space left over. Minus another 3" for distance under hood plants should be maxed out to grow to avoid heat damage.
So that still leaves 8 inches to play with. I wouldn't push the WW past 12" veg and the AK48 past 15" veg for 30" bushes/trees.
Also, IF you had to raise your light to it's MAX possible height, how much distance from the BOTTOM of the hood to the TOP of your buckets ?
THAT is your grow limit, height wise.
Break that distance into 3rd's and at 1/3rd is your max veg height, especially if you're gowing Sativa dom hybrids (more than 65%) for a 3x stretch.
For 50/50 hybrids and/or Indica dom hybdrids, you have a few more inches to play with and may even need to do some training until you learn a strain from running clones.
Me myself, and following the Inverse Square Law, 30 inches IS my max plant height with my 430w Hortilux to give max light penetration.
Another reason I'm going back to SCROG next grow in 4 weeks.
Can't beat the yield for the amount of space used and total plant matter utilized with EVERY part of the plant getting equal light.
I'm done rambling.........smoked some JillyBean right before answering this ! LMFAO
