He meant Compact Flouresent Lights. They are also used to grow, they are cheaper and give off way less heat then HID's but aren't as good as HID's when it comes to yield. As for the medium lol...medium is the type of growing compound? you use to grow. Ex. soil, hydroponics?

(I hope i explained the medium thing well) =\
BizzyStick Reviewed by BizzyStick on . Any advice on starting.... Hi All, Basically I am looking to setup my own system, My two biggest problems are size & smell- to be in my Garage (+ the fact I have never grown before) I have seen some very good enclosed systems (blackbox/quick grow) which would be ideal, but they are a bit on the big side for what I need. Are there any smaller totally enclosed systems which are as easy to to use similiar to the two mentioned? (have you made one and willing to share how to?) Please, if you had a chance to start again Rating: 5
