I am planning on letting my plants grow outside, but Im not sure how big they are going to get. I was going to cut holes in the bottom of the pots so if the plant out grew the pot it could send roots into the natural soil. Is a 5 gallon can big enough or would seven gallons be better? Or do I need still larger, because pot get expensive.

I suggest you plant directly into the ground. Thats the great thing about growing outside. I know some indoor growers dig up their basement floor just so they can grow in the earth.

Five gallon pots should be sufficient but I would also suggest just planting right into the ground because you will otherwise have to constantly water the pot, and go through the trouble of digging a big hole to place it into. Go organic

Don't plant directly into the ground...
Start the baby off in the 5 or 7 gallon, then work the soil and dig the hole to transplant it in.
This way the plant is strong enough to withstand the local soil and it's pests.

hold on people, I have well over one hundred plants and im not going to dip that many holes. I will did a 4-5 inch divet to put the pot in and then put holes in the bottom of the put so the roots can go into the ground. But the soil is so poor, hard and dry here in the desert that digging would take forever and probably kill my plants. So I really need to know how big of a pot do I need??????????????????????

5 gal will work fine but the bigger the pot the bigger the plant. and it sounds like you are going to take care of them ie water and feed?

I plan on setting up an irrigation system using pvc that will do most of the watering, but yes I plan on feeding. How often will I need to feed?

100 plants?!? Dude, you don't have worry about helicopters - this grow will be visible from outer space.

100 plants outdoors in pots with an irrigation system. That's a mind boggling amount of work, from care to harvest. The risk profile on this exceptionally high, particularly given the time you'll need to be around them. And LEO will stake out for 100 plant bust.

If they're in pots, your looking at feeding every 7 - 10 days IMHO for peak growth.

Good luck, and be careful.

a foot every gallon, outdoors can get pretty big. I'd say 7-10 gallons just to be safe. this bagseed or strain?
