So I am just starting my first hempy grow. I am using 3gal black Buckets. I have read that the the perlite can grow a algae on the surface. And that this was due to light exposure On one I cut a 2” hole in the lid and and letting the plant stick threw. I also put a few 1/8” holes in the lid it’s acts like a drip ring while being watered. Anyone see a problem with puting a lid on the hempy?
