Want to know the effectiveness of the HPS bulbs that run in MH ballasts. Does anyone know if the HPS conversion bulbs work as well for flowering as Standerd HPS's In HPS Ballasts?
I got my switchable MH/HPS through HTG SUpply on ebay. It came with both lights, and I had a great result with the switch. They did offer a different HPS upgrade bulbs, but for my 6x6 room the light that came with it had plenty of lumens and my yield did not suffer, in fact it was the biggest yield for me to date. I have done grows under flouro CFL, straight MH, and now the switchable MH/HPS. The latter being my best result!! Some say that if u stick with MH through the whole grow u will get denser buds. But I feel that has to do more with your strain, how u fert/nute your plants. I go Strictly BMO(ebay) for all organic fert/nutes. Much tastier and smoother buds by far. I have used advanced, foxfarm and BC, but had way more success with 100% organic Blue Mountain Organics. My buds were whitewidow, G13, tiny bomb, light of Jah, and a combo skunkx haze. I 've done side by side grows comparing yield, taste, quantity and ease of application and have found that organic for me has been THE WAY TO GO. Fox farm is not 100 percent organic and can easily cause nute burn, although I've had a good grow with their products. Taste was sacraficed compared to 100% organic. I would stay with switchable and make sure your reflector covers your entire grow area. If u want bigger yields, try scrogging your pups or fim, supercropp or ol fashioned topping. Scrogg has given me great results and massive buds, potent buds. Ebay super plant tonic and you will find BMO, and die with the prices.. Super cheap, but they are producing the best 100% ORGANIC TEA CONCENTRATES, and they are awesome in explaining any questions and their customer service is second to none!!!! If your worrid that u have a cheap conversion bulb, go to HTG supply (ebay) and upgrade. Measure your grow space and see what suits you the best! Good luck and holla if you have any questions.. Plants typically need 3000 lumens per sq. feet to do their best, i currently get around 6000 lumens per square feet and my plants love it!!! Take care, and hope this helps
