ok both of you are having light shock problems when you change your lighting to a different kind of light/spectrum the plants go into shock they dont like it at all sooooooo you can leave it under just the ufo and it will adjust or both cfl and ufo either way its going to have to adjust to the ufo its better to stick with the same light except when switching to flower period but i would awsome the ufo is better than cfl's altho ive never tryed it trying to decide whether to get 1 or not they have some on ebay right now starting at 99 cents with 9.99 shipping!!! yes i know you guys said dont get the cheap ones but im on a budget and i dont really need it im going to add it to my cfl's and slowley take cfl's away hoping it wont shock them but it probably will maybe ill wait and use it on my new clones why are different brands better than others can anyone explain and will the cheap ones still work better than cfl's im currently using 12 26 watters on 2 plants vegging.. but im going to be adding 2 more plants and 2 more cfl's tomorrow for budding I'm using 400 watt hps but i live in a very very hott climate this summer i might want to use the ufo to bud while its hot maybe 2 of them what do you guys think?
