I have similar conditions and same issues with the pests and mold. Being able to move plants around that are in pots might be a very good idea!
If you have room for a compost area 4'x4' then defiantly save all your kitchen waste like old veggies, coffee grinds, etc. Every month I get a 5 gallon full bucket of moldy rotten stuff that goes in my compost pile. Many years ago I bought 500 red wiggler worms as was previously mentioned, great Idea to add them. So all my oak leaves from fall get mowed then dumped there and grass. I don't use weed and feed on my lawn so no issues. Composting leaves can takes years unless you have a perfect ratio as I learned so in the mean time you have to do an alternative approach and you may not get enough either so sometimes I have to mix it up and supplement but always for me and my preference it is done very sparingly if using chemicals and not too often. Typically I stay with compost, organic additives found in super soil recipes, and OMRI labeled stuff.
This year I am growing in a 16'x12' cold frame green house and I will have fans and possibly a dehumidifier not sure how that will workout first time like this for me this year. Hoping this will help me with the mold issues. But also new this year is a 70% Sativa strain I am trying out instead of my typical Indica strains so hoping the buds will be not as dense and help with air flow through and around the buds.
