Cheers, I'm going to make a new post with my new discoveries soon, but meantime here is an experiment with them buried at two weeks in Hydro, the purpose was to see if they could take it, they did, and that means I can cut two weeks off my grow, if I need to. Using virtually no space. And finishedNice grow, well done!
Years ago I saw these pyramids at the hydro store. They were a curiosity but at the time I stayed with soil.
They don't carry them anymore.
