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

Mackerel's! Those are nice roots! I get a few stragglers in my root style pots that are twice as deep. I think you have the pot there! Are they taking ca and mag from the soil or do you have to use an additional cal/mag or epsom? Sweet roots!
