Ok, again back in the day the old Overgrow people said make your cloners out of dark plastic do not use clear plastic because the stems need to be in the dark when you’re trying to root them otherwise it won’t work…well guess what people that was just a myth, that’s why I made one out of a small black container and one with a clear container…I had 2 cuttings same strain and 1 went in the dark one and the other cutting in the clear one and they both started showing roots at the same time with optimum conditions. Ever since then I’ve been using both of them with no problems. As you can see the top of my clear cloner is blue and it blocked most of the light from the water that’s why I never got algae. As long as the light is not shining on water you won’t get algae. I also made another clear cloner that busted another myth but that will be on another post…
