pot size

how big of pots should i be using for 3-4 foot plants under 1000 watt

2-3 gallon pots.

i have them in 1 gallon right now 3weeeks into veg do you think i should trans them to 2-3 gallon, was going to bud 25 dec

Dont know if ur talkin about 3 or 300 plants.
I use 5 gals buckets with some rocks for drainage,works well.

I think he means he has three 4 foot plants, or he was saying he has one 3 to 4 foot plant.

i grow 10 to 12 plants in veg then place them to bud room. which can hold about 25 plants i grow them to about 3 to 4 feet tall

ok, I understand.
I'd personaly go with 5 gals(if growing from seed,not clones)
I used 3 gal on my last grow and I see a differents in the bigger buckets
just in the over all health and thickness of the stems.

the bigger the bucket the bigger the plant.

I agree, go with 5-gallon pots.

I use 3-5 gallon pots depending on which area I am growing and whether I want less plants that are real big heavy yielders or more smaller sized plants with nuggs.Transplant as few times as possible.I try to start in the pot I will finish in if possible

this is a 26 inch plant in a 2gallon pot i will get the hole grow out of it

and some of the bud on it. 18 days into flowering. good luck with your grow
