    Default How much light in a 4x4 grow tent

    I recently picked up a 4x4 mylar lined grow tent which i am pumped to use. I am going to use it for flowering, and I want to use ceramic metal hallide lights. Is one 400 watt light enough to cover this area or should i get two of them to really pump out some light? All input is appreciated. I will be using dwc and want to use all the space possibly in this tent.

    I would but 400 is the highest wattage they come in. Ill probably get two 400 watters so i can have two flowering stages so i can harvest every month hopefully. now should i go with cooltubes or adjustawings? sorry to change the subject of the thread.

    You can have two flowering stages under one light. And you will more than likely want to use cooltubes on the lights. It is soo much easier to get the temps under control when using a cooltube and i have found that it is really easy to keep the temps stable both in the summer and winter months with just a couple small adjustments.

    probably gonna go with a 600 watt hps with an adjust-a-wing- or the euro reflector, 1000 would get too hot for me so 600 shouldnt be too bad. just need to figure out what reflector now. if anyone has any advice for this set up it would be greatly appreciated. smok on

    600 is perfect...make sure you go air cooled on the hood and get a inline fan...youll be set!! gl

    Hmm...a good rule of thumb is 50 watts of HID per square foot. So a 4x4 is 16sq ft = 800 watts. But in an enclosed space 600 will do.

    I can recommend a good reflector for you. Sun Systems Brand "Super Sun" reflector. Theyre around $100, and include tempered glass, socket, cord, and air fittings for both 4" and 6".

    I wouldn't go less than 600w in a 4x4 tent, if you can ventilate it enough and keep it cool go with a 1000w, or even 750w
