thanks Mcbuds,
actually, i doubt they're going anywhere.
the RW cubes are made to fit in the green sleeve right? and do you see how the sleeve goes a 1/4 inch above the slot in the side that fits into the channel? well a single RW cube comes maybe 1/8 inch into the wheel to keep the cube in place. . . so with the RW hanging out of the side like that, i had to push down the RW on that part like 1/4". even after i did that they put pressure on the wheel. see the crack in between the cubes? thats from the pressure on the outside. but i left them full size in th middle so they are being held in from that ledge. . . on top of that they just barely touch both of the sides of the tent when they turn (prob not good, but can't avoid it) and dont touch anything else so i dont really see them going anywhere.
I really wish i could figure out a way to cover most of it somehow to keep the light out, but not affect feeding.
i don't know McB, i don't know what advice anyone can give me, i just can't seem to get a vigorous root system in RW. i hope the bacteria help. so far i am not impressed with the root sturcture this grow either. only one week into the AN nutes though, so i will stay hopeful.
I am a smart guy, i have good meters, calibrated, and i know what and what not to do. I don't know why this eludes me. its frustrating when i can do it so easily in dirt.
