I am looking to order a HPS light system for flowering when its time. I have 5 plants. How many watts would I need for 5 plants? I have been looking on eBay theres 150w, 400w, 600w, 1000w...

how big is your room? how hot does it get?
1000watters are preferd because of the same cost for a better bulb.
but since you have 5 plants get the 400 or 600

the 600 is most efficient; remember that the 600 and 100 will both use more electricity than a 400. With 5 plants a 600 would be a good choice. However, if you have a well ventilated area with cooltube etc, go for the 1000w

Well im defiantly not going with the 1000w its too much and i don't need it. I'm debating between the 400watts and 600watts. The prices between both is not that big of a difference, so money its not the problem. Should I go with the 400watts? and save money and since I'm also only doing 5 plants?
Or the 600....?


This is the 400 WATTS :

what's the dimensions of your box? What's your ventilation? If you have a good fan and cooltube, get the 600. It penetrates the lower foliage much better than the 400.
