I am undertaking an ambitious quest this year to grow a large variety of plants in containers. I made my first basement style grow area complete with LED lights and things are going well. I have grown peppers in the past and always use pots. I live in northern canada so a typical garden would have too short of a season. To try to keep cost down i have been searching eBay for deals on pots. I figure somewhere between 30-50 will be good but i am hung up on size. They all go by nursery trade size so i am thinking the 3 gallon will be sufficient but dont want the surprise of taking delivery of a pots that will be too small. I will have jalapeno, habanero, reapers and trinidad scorpions as well as several other varieties. What size pots would you guys recommend? Also, any Albertans with a good line on where to pick up a quantity of them for cheap would be appreciated as well. Thanks in advance
