I just planted two seeds today into standard 1 quart round garden containers and placed them in the tent. I put them directly on the floor of the tent though, they need warmth not air right now. I'll transplant before they get root bound, how long that will take I'm not sure but when I see roots popping out the bottom (I have 4 square holes in the bottom sides of my containers) I'll transplant them into 3 gal smart pots. Should I flower in bigger smart pots or is 3 gal good?
I flower in 3 gallon fabric bags, and plants look good and grow tall. You can put larger plants in these bags because the roots occupy more of the soil.
Ive got some of Sam's Skunk x Haze that are around 55 inches tall in my 3 gallon bags. They also suck the bag dry in 2 days too..so you had better be on your watering.
This was with 2-3 weeks of time in the 3 gallon bags before flowering.
