i'd be worried that you'll have plenty of light until they go 12/12 stretch
In order to have a good yeild using the light you have. I'd do a scrog
that way you have just the tops to cover with light instead of trying to getlight through the canopy. and for your bubblers I use 8' air stones lots of air making a mist of bubbles Light makes algee so keeping the roots 100% dark is a must.... Now for your 10 gallon totes are they plumbed for filling up and draining?, for instance when i grew in my homemade bubblers or other hydro systems I learned that I have to change the NUTES out alot clean and healthy Nutes I change them atleast twice a month maybe 3 times depending on the growth cycle and time per Life cycle of the plant including time to flush thats alot of water!!!!!!!! So plumbing is the first step.. Hoses on a cheap fountain pump will work to empty the tanks just fine for less than 30 bucks!
Get a long funnle to fill the tanks also cheap and reuseable
and speaking of water are you using tap or RO, Hydro really needs RO
i'd go to the store and get it for 50 cents a gallon Now it cost $1 buck a gallon you have 3 10g totes so youll need atleast 60 gallons a month min for a 2 time/nute change, and if you dont want to look like the thristyest guy in the town I'd go get a $200 hundred dollar RO set up... General Hydroponics nutes are set up for RO water speaking of general hyrdoponics nutes do the lucas blend of nutes/ has the micro nutes also


o' I remeber hydro now its a pain in the ass!!! Costs too much money for me But I grew that way for years Bubblers, ebbnflo, areos, DWC, Dip n slpash
hell no more for me JUST STICK EM DIRT cheap and easy :smokin: IMO of course..
