3 gal pots?

would 3 gal pots be good enough to grow in outside ?also gonna use worm castings will i have to use nutes for vegggie state or just for flowering?

3 gallon is a good size, I personally like the 5 gallon buckets that you can get at Home Depot or any other hardeware store for like $2.50 a piece.

You will want to give your plant an all around nutrient during veg, something like 20-20-20.

Then in flowering boost the phosphorous up, so a 17-51-17 or something like that will do the trick.

thx got ff nutes how much water should i use per plant?

You should water until it starts to flow out the bottom. You want to thoroughly wet them when it is time to water. The plants will drink at different rates depending on their size, heat, sun exposure. Each plant may drink at different rates so what I do is keep one extra pot filled with same soil and make sure i keep that one dry. This will be your guide. Once you get to know the weight of that pot, you can then make a very informed decision on when each plant is dry.

You'll only need to do it a few times, then you'll just know.
out.
