There are flowers and veggies I'd like to start indoors, but I'm confused about which system to use when. I'm getting some grow lights, because that seems like a good idea, and I've set up a mini-greenhouse thing on the deck. My current thought is to start plants indoors with grow lights, then move them to the mini-greenhouse later on. And the warming mat? I suppose I use that in addition to the grow lights if the seed directions say "provide bottom heat" or something like that. Does this sound right to you? Also, if I'm using grow lights indoors, do I need those clear plastic dome covers for seedlings? I'd appreciate any advice you have to offer.
