I have a new ufo with 2 watt (90watts) led's can i mount it verticle and use it as suplimental light? I also have 125w cfl's which will work better for the lower areas of my closet? Thanks for any input it will be greatly apreciated thanks jack!
Yes, you definitely could supplement your 1000W HPS with a 90W UFO lamp, but I question the need. 1000W is a lot of light, and a 90W UFO, not that much. How much space have you got here that you think 1000W isn't enough light?
If you have an extra small light handy, I'd suggest using it instead for seedlings and to root clones. That way you can keep a ready supply of new plants handy for transfer to the main growing area, at minimal energy cost. You could also use it to maintain a "mother" plant in vegetative mode to take clones from.
Two 125W CFLs, would also work for side/supplemental lighting, if you wanted.
Alternatively, you could use them to setup a small separate vegetative area, again with the idea of increasing your ultimate yield. So you start the plants under the UFO, transfer them to your veg area under 250W CFL when they're maybe 6-8" tall, then keep them there until ready to flower. If you do this, every time you harvest a plant, you'll have another one immediately ready to be put into flowering to replace it.
