Rs11 clones alien rdwc v system

Well it's all gone to shit. Water temps can't be controlled with lights turned up..so turned the 1000w dimluxs off and now running just 4x 400w hps..had to stay in veg..given the roots and good wash and bath in alien rot x solution. Filter on circulation pump blocked with the gunge that's come off the roots..cleaned and refitted. 2 weeks before bigger chiller arrives. Keeping temps below 19c with lights turned down. Fingers crossed the roots recover nicely..
