So Doc what you saying is he height is not good enough and from what the info i provided and your knowledge what is the best results i can produce
Your going to need at least 1 ft of height for the hangers and the light hood and at least 20 inch's of space from the hood glass to the top of the plant canopy.....That's roughly going to be 3 ft.....you now have 4 ft of height for the plants, so abso-fucking-lutely a flip to flower plant height of 24 inch's MAX for Indica's.....I mean I could get really technical with strain heights and flowering...but a 20 inch max plant height at the flip will be your limit.....Strain dependent, you'll still be supercropping them to fit with some strains so for a safe max plant height at the flip - - 16 inch's until you understand what I'm talking about and why (strain dependent growth in height after the flip to bloom). I don't feel like explaining that in detail as I still feel you need to simply do some grows and figure out what your doing. When you do,,,,,you'll Know what I'm talking about here...
Your new and you want the best results possible right off the bat.....Nice idea, but not, unless your very lucky, won't happen....
To make things easy for you.....I suggest this for
your best results.
2 gallon pots and flip the plants to flower at 12 inch's in height...
Use Dyna-Gro Foliage -Pro in soil, start to finish and
don't let
anyone talk you into a 2 or more part veg and separate bloom feed till you've done at least this grow run! Dyna is easy, simple and won't screw you on a mistake.....Feed mix, then straight water, then feed, then water....repeat this method,,,,,do NOT feed every watering!
Learn now, NO FLUSH!
For you, pH all ingoing to 6.5 and forget about soil pH!!! don't second think this...
The only thing I might consider adding,,,,would be Dyna Pro-Tekt. A silica supplement.....It will help with heat tolerance among other things.
If you follow these directions and go to a 1K light and run those 16 plants at once....You should get a 2lb+ return of dry product!
Heat in an attic
will be an issue for you! Plan now on A.C. supplementation!
Good luck
Doc
