Also it doesn`t help feeding nutes to clones,the nutrients will restrict root growth,if you can put the clones in a propergater or humidity dome,go 4 it,if not just spray mist them each day as the cutting cant get water due to lack of roots...so it absorbs water through leaves at first until root system is established.....i lost the first 2 sets of leaves(yellowed) and once the root system grew 4-7 days it picked up again.....good luck...But like they say above the light is to much....it creats dry heat......you need humidity for clones...get a propagator...peace
