*this is the RIU Ultra Violet "thinktank"... so if its relevant in some way, please do shareOk i still haven't found the info on uvb radiation and envirolite cfl's but i did find research relating to the fact that just two twenty min a day lights on from some uvb lights is good enough to increase thc etc etc and longer light periods make little more difference.
Maybe its been covered on this thread already but thoughts and feedback on this would be good. Peace
--cheers
