Honestly I'm not sure how I feel about the growbright bulb. It's rated at 4100 Kelvin rating. Something in the 2700K to 3500K range would be better I think.

I got the same bulb sent to me as a replacement bulb. I'm sticking with my GE Floralux 400 watt hps bulb. 45k Lumens at 2700k kelvin. It's 10k lumens less than my growbright, but at a better spectrum.

It's all set up...pump in bag, heater, airstone, netpots with Hydroton, and drip spikes. Darn! I have Blueberry seedlings ready to go in the rockwool, into the hydroton and get going. I only used my Cooltube for one grow, about 2 months; could it already need a new bulb? It flashes every now and then, like it's trying to start. Any ideas? :( Ldy Rating: 5
