Only giving it 4 stars as when I set it up my plants were 4 weeks old and had been growing under regular 1000 watt light. My leaves all wilted and I thought they were going to die. Two of them morphed to males, the rest did recover but a few grew balls and gave me some pollination. I belive it was the shock of changing lamp. Have started some new ones and raising them under it from the start. 1 week above ground and looking good so far.GROWACE RESPONSE: Thanks for the honest review! Keep in mind that the double ended bulbs are very powerful and have strong UV light (which is excellent for vegging as well as resin growth). If you find that your leaves are wilting, it's likely that you have the light too close to your plants. We highly recommend that you raise the light to avoid any light burn. The kits do come with rope ratchet hangers so it makes raising and lowering of the light very easy. You'll also want to remember to raise the light as your plants mature.
