It's not the kits it's just the method of growing. You can build a system for yourself with a lot of the parts coming from the 99ΒΆ store. For one or two plants and only a few ounces of bud is your goal every 4 months or so then it's fine. The light will work but will you get a pound of bud with it-NO- not even close but will it grow some buds then YES. It's just a method of growing, there are some things you will want to add later on but why not get started now and learn. A good book is a must for any grower; the forums can be so overwhelming and are filled with dribble.

Good luck
