Sounds good to me. I grow most of mine in 12" pots that are 10" deep. I also grow a lot of them in black plastic nursery pots and that has not been a problem but I don't know if the metal will make a difference.

would not trust the metal pots because of the rust and the metal may cook the roots just my opinion. only did containers one time and used 5gal. plastic

let it burn

I've had no problems getting good harvests using 5 gallon buckets and last summer I even used 4 gallon buckets with good results. During the off season I troll the alleys while walking the dogs and collect more and more.

Container soil is a different matter. You might want to pop into the container forum and read up on that. Growing in containers is much different than growing in ground.

I say go for it. If the containers act as a heat sink then so much the better for the first few months. The pepper plants will love it. Pile grass clippings, leaves, straw etc around them if becomes a problem during a hot spell. Then an occasional wetting down will further cool.

Ask around at landscaping companies and nurseries. They just might have hundreds of used containers and will sell very cheap or give them to you. Try for 7-8 gal or so.

I use 5 gallon buckets with much success. I've also used metal containers. Because I am almost on the Equator(Hot tropics), heat is a problem even with plastic containers. I usually sink the pots halfway into the ground and make sure to check the moisture content of the soil twice a day during hot spells (the base of the hole in the ground should have sand or gravel). I normally do not need to mulch as most peppers I grow love the hot weather.

I bought some 10-12" pots at the dollar store. What part of CT are you from mommyandme? I'm in the Norwalk area.
