I'm thinking of buying some airpots for next season but am wondering what size to go for. The website mentions wide 10 litre airpots for chillis, whereas all the airpots in 3, 5 an 7.5 litre sizes are taller and meant for starting trees and shrubs. All my chillis this year were grown in 3 litre pots and I'd like to pick something bigger this time but 10 litres is quite large and expensive.
