Think of it as basically a ft. per gallon. whats your height restrictions? I would transplant first... wait a couple days at least for them to get over the shock (possibly wait till you notice new growth) then top and FIN if you want.
impressive for cfls man
Looking for new growth after topping is imperative. So I wouldnt suggest putting them into flower until you do or it will create an immense amount of stress. Transplant = stress. Topping = stress. Introducing nutes = stress. and Putting into flowering = stress. and unfortunately stress = Hermies... So the most you can space out those tasks the better. They look amazing homie, and their going to flower great. Should take on a liking to those nutes right away and love their new 3 gallon home. You planning on getting more light for flower?
just ask her for a decent soil less mix
You're growing tomatos or a house plant or something, and you read online that that is the best thing to go with and so you want to try...or you could shop somewhere else. Is there a Lowes or Home Depot near by?
What are the specs on the bulbs you're using? Watts and Color temp specifically
I'ts rare, but I've heard of plants showing at 3 weeks
Nice, I've got 2 day light and 1 3000K on my oldest plant and then 2 and 2 over my 2 seedlings
Would have to get a plug in for it. Plants are looking top notch, temp looks a little high, get that down a couple degrees if possible. Also what are we looking at for humidity? Good luck on the transplant, remember low stress training
