They will grow another foot or more during flowering. Watch the temperature at the top of the canopy and don't let it get to hot. You can always bend them if you need to keep them under the light.
Zandor Reviewed by Zandor on . looking for input this is my first time growing and I'm using hydro to boot. I have an igs drip system which is 3x3 and holds 20 1 gallon pots with a 1000 watt hps and a couple florecents on the sides. right now i've had them on 24/24 for exactly 3 weeks.. from my knowledge their looking great all a little over 1 foot and fairly bushy.. i was planning on changing the resevoir today adding ionic boost to the solution and cutting back the light to 18/6 for a week and then 12/12......I only have 4 feet from top of Rating: 5
