Heres a few... First pics... Two weeks into from clones, and more recent 4 weeks, and topped
Last pic is just of the room its in. I have 12 plants ready to flip to 12/12 in a E/F bucket system. My clones arent ready to fill room yet, so Im letting them all veg longer
Back when i did rdwc in 30 gal. trash cans (vert.) i used sm-90 w/ hygrozyme and it helped my roots alot. wish i had picks to show. they filled most of the trash can.
You can only get these type of roots from high pressure aeroponics. Note all the fine hairs covering the roots. This provides more surface area for nutrient uptake.
Because of greater root mass per plant, you do need more room between plants to avoid hammocking. Also, the greter the root mass, the more and bigger the buds.
