yeah i thought so too...when i was building this cab I was having issues with heat build up in the resevoir and the cab itself. I think this caused a little heat stress. I have all that under control now, 85 degrees consistent and the resevoir stays around 77-79 which i think is a little high but i can deal with it. this is just the 1st run so I'm sure my next grow will be a lot better...hopefully. I've been reading around on this forum for a while now and have learned a lot from you SICC preciate it.
