That's one of the things I disagree with lol. I did it for three years and yup grew plants but nothing compared to what they should have been, I got the rot using microbe lift pl, yes a pond microbe lol. So is that you cloner or your growing tote? Sorry like I said old and confused lol. Yes play with the height I guess, like I said my nozzles were all 180's on the outside and middle for that matter. Here's a pic of root chamber just as rot was setting in, yup lots of light getting in as I now see
. It's to bad it didn't work out for me, I had just finished another one and was hoping to just swap just the lids to different totes in different rooms
