      @Jimboo what lights in what size space were you running into problems? I know vegging plants want around 5-600 umol psm and I'm running 625 so like Farmer G says I thought it would be sweet. Took the plants out to look in daylight and despite a bit of cal def they look good.  Ive switched the third light back on and I'll monitor they see how they get on. Cheers for all the input from everyone much apprecited
