Hi, I'm a first year gardener. I have a bunch of peppers and tomatoes going out in a week or so. Most are going in a raised bed, but some in containers.

For the containers I'm planning a mix of 50% potting mix (mostly peat, no soil) that has worked well for my seedlings, 25% compost and 25% perlite. Does that seem ok?

Can I use LECA in place of perlite, or is it too big? Reason I'm asking is that LECA is way way cheaper in my location (Norway).
