I am looking to bulk grow next year for my crops to be sold at a local store. I have found using large plastic storage boxes (Like the ones that can go under beds) work well. However I have put the storage boxes then in my plastic greenhouse, which I maintain temperatures of lowest being 9 and max 23 degrees. Should I have drilled some ventilation and drainage holes in these boxes and how many days should they be left completely alone before lifting the lid. Thank you for any information.
