if your talking about 10x20 and your gonna use like all of it? well then id say do the 8 1000w's if your really gonna need that much but thats like 16 pounds a harvest with a good strain, id go with the above recommended, get 2 1000w hps's, and then also get 2 1000w mh conversion bulbs, use the metal halides on 18/6 until plants are ~3 feet high, then switch to the hps on 12/12 until trichomes are to your liking, get a gigantic canfan with a big filter to stay off the radar, and cool tube those 1000w's with it also:thumbsup:
stinkybudz Reviewed by stinkybudz on . What light system for few large plants? We are about to grow 18 plants under cal prop 215 with 3 recommendations, well within the law, but have never grown before. I've been reading about light requirements the last few weeks and taken in tons of info. However, we have a large space for growing, approximately 10' by 20', which seems huge for only 18 plants. Is it possible to grow very large plants indoors to maximize yield?Based on square footage seems we'd need to run 8 x 1000's, but that seems ridiculous for only 18 plants. I guess Rating: 5
