my plants just sprouted taday i have two rooms right now 1 with floros and one with an hps both in miracle grow the hps took 4 days for the seeds to root the floros took 11 days. Just for your information no one ever grows wit floros so how should they now five will do the same as an hps but to get it the same u gotta wait an extra 2 months i suggest going to home depot buying a hps fixture for 50 bucks and buy the 20 dollar 400 watt hps if you wanna do like hella good growing get some rockwool and get a water pump and than 6you got hydrophooics setup and that ttakes about 2 weeks for half a foot
