So I'm building a pc grow box to house my seedlings until they are ready to plant. Everything has been set in place but I'm stuck on weather to line it with Mylar or should I just use this heavy black plastic that I already have? The thing is I'm only keeping seedling in here until they are ready to place in my dwc setup so does it really need the Mylar? And if I just use the heavy plastic, should I line it with duct tape first? I normally do my seedling in my grow boxes, but I'm wanting to expand my operation a little lol. Any and all info is welcomed...thanks!!
if theyre just seedlings they dont even need that much light you want to focus on root system i believe. i wouldn't waste the money personally, id spraypaint white or some shit, probably not use a pc just giving myself a bit more room to work
