I'm sure most of you have heard of organic growers using hydroton or sand in the bottom of their buckets for proper drainage and aeration but what about making multiple repeating layers of hydroton/soil/hydroton/soil/hydroton and so on without mixing the layers. I was thinking of doing this in addition to making many small holes in the buckets only where the hydroton layers are for aeration. Would salt buildup be an issue?
