What size pots do you recommend? I bought a 4x4 tent, a 640-watt LED spider light, and I'm unsure whether to put 9 three-gallon pots or 6 five-gallon pots to get the maximum annual yield.
If you are growing in soil 3 or 4 weeks won't make much difference. If you want the most weight the fastest then 9 plants would be the best plan. And like I said you can always cull one or 2 if they get smothered
Kind of up to you really. What are you growing? autos or photos? how long do you plan too veg? I'd probably go 6-5 Gallons with a 4 week veg if your going photo.
