I haven’t grown with coco in a long time but I have a feeling these pots would be great for soiless. I’m finishing some DP Auto banana Blaze right now in rain science 2gals with 50/50 biobizz light mix & coco. The first pheno had a yield of 62grams but the bud had zero trichomes and zero terpenes, it was the worst auto I’ve ever grown. The second pheno I had was frosty and full of terps but only had a yield of 49grams. The third pheno i have is finishing its last day of darkness before I chop and that thing is a monster. I’m guessing it’ll be at least 70grams.
