I had to give up on my old pot head ways because I got hired as a police recruit. No more marijuana lol anyways, I still have a large variety of psychedelic plants I take care of practically like my children. Oncluding salvia divinorum, calea, damiana, kratom, and a bunch of other stuff. But I just read up on the whole using Co2 to help plants grow Lrger and healthier. Well the most obtainable form of Co2 for me is Dry ice (i buy for the kids to do fun science activities with) I keep each individual plant/shrub inside of a large humidity domes inside my garage under grow light and also placed next to the window. I was wondering if I place a small chunk of dry ice inside of a small container filled with warm water and place them inside of each plant dome, would that be effective? Will the cold hurt my plants at all? Wil the Co2 hurt the ladybugs I have in a few of my domes?
