grow bag

Hello everybody! My name is Chantal, I am from the Netherlands and I started gardening seriously last year. Before that I tried to grow herbs in the windowsill to cook with. I love cooking and I would like growing my own food and especially foods you can’t find in the supermarket to use in...

I'm new to grow bags and heard that peppers do well in them. Does anyone know if peppers will do well in 3 gallon (11.3 L) grow bags, or should they be in 5 gallon (19L) bags? I have both, and I've looked up this question elsewhere but can't find a good answer. Thanks.
