I was thinking two gallon pots.
Would that work?
9 weeks veg in 2 gallons sounds like setting yourself up for disaster. Going to get big and take more water. You will be constantly watering and may dry them out. 9 week veg is long af. In 4 weeks my girls are busting out 2 gal smart pots.
I had 12 3 gallons in a 4x6 and had 25 some doubled up.
Grew with salts and had 6'5 ft plants scrapping the 1k watt light.
Less is more with good training I say.
I agree with everyone who stated....I use fabric and it's a lot of hand watering, but I prefer those pots over plastic.
Using the same strain will enable them to work together rather than against each other I have noticed in my growing and conversations with SCROGers.
