I can attest to roots up top…one feature of the soil cover is light blocking and (if the cover material is thick enough) it allows roots to propagate on top of the soil…
yup the elusive weed air-roots cuz they won’t develop unless it’s dark AF and moist too
also the ones that fit in saucer under your grow bags are potentially risky business… runoff water, the whole combination of electricity & water thing. Plus seedling heat mats are larger and can be tie wired or duct taped to sides of your smart pots as shown, but if heat mats are sitting up on cookie sheet above the drip pans then that should be ok
