Organic no till beds work well for autoflowers, provided the soil is cycled and alive before the seed goes in. A freshly mixed batch with hot amendments will burn a seedling, and an auto does not have the weeks to wait for it to mellow, so build the bed at least a month ahead. Recipes for a light auto friendly mix are posted on https://turboautoflowerseeds.com, with lower amendment rates than the usual photoperiod versions. After the first run you mostly just water, which suits autos.
