What kind color is the light that comes off? If its a oddly orangy yellow its probably an HPS which is good for flowering and can be used for most of the grow. I would make sure it isnt a mercury vapor though because from what I hear, they do nothing for growing. I would think it should have some writing on it somewhere to help you identify what kind it is. Even if you just found the brand name and a model number you could look up what kind it is.
At the very beginning though you are better off buying some cheap ol CFL,s to get that seedling going.
hatecable Reviewed by hatecable on . 400watt hid nubie question I found a 400 watt hid light not in use in our barn...ballast and all! It has a large aluminum cover. It was an overhead light at one time. My setup in a 5gal bucket, fan and this huge ass light about 3 ft above my soil. I haven't seen anything come up yet but I am anxiously waiting. My question is, is this the right type of light? Thanks in advance. :weedpoke: Rating: 5
