oh and tightpockt i forgot to answer some things you asked cause i was in a rush earlier...
i have mine set to not have any runoff but i can feel moisture through the sides of my 3 gallon smart pots from the very top to the bottom... it's not soaked or anything but just the perfect amount of moisture to keep the plant really healthy. within 4 days of transplanting the seedlings into these pots their roots had hit all sides and were pocking out through spots all around the bottom where they had been air pruned by the smart pots. by the way, i transplanted them when they were only about 1 centimeter tall each and they were in the rapid rooter plug that i had germed them in too.
the combination of these blumats and stuff like airpots or smart pots is unreal... coco also makes everything work perfectly and i don't think soil and blumats would get the same fast acting results.
I'll have to check out bushmaster for sure next time. i had my gf supercrop 2 of the highest branches to even it out more with the blue widow. pics are below...
