OK, I am still new here, but I got such good tips in the first post I asked a question in, I thought I'd ask another. Back in High School, a friend and I grew a few plants outdoors. I lived in the country, by a creek, so we planted a few seeds near the creek. Just kept an eye on them until we could tell the males, yanked em' out, then let mother nature take over. We had heard we should harvest right after the first light frost. Thats what we did and ended up with some pretty good smoke. Now my prob. I live in the city. Smoke is more expensive here. ( More hydro ) So I wanna try to grow a little of my own to try to save a little money. I looked through some of the old posts here, and the narrowest cabinet I could find was 24 inches. Mine is a little narrower. Here is what I have to work with. I have 2 metal cabinets. Each one is 36 inches wide, 18 inches deep and about 6 1/2 feet tall. I know they are tall and wide enough for 1 or 2 plants ( I figure 3 would be pushing it.) But are they deep enough. 18 inches doesn't seem too deep to me. And I can't push them together to make one big one either. But if I could use them for growing purposes, what all would I need? I plan to start out using soil. Unless hydro is easier. ( It doesn't look too easy to me. ) I don't have a lot of cash, ( few hundred saved up. ) About what will it cost me for a light, and what size would I need. And about the ferts, what kind? I guess my main question was is 18 inches deep enough for a plant, And IF I can use them, What size HPS light would I need? Any replies would be GREATLY APPRECIATED! Thanks!
