Re: Minimum Amount of Light Watts/Gal Required? First of all I have to give it to you for being immaginative.I have never heard of anyone useing vegetaqble growth as a defense for metal halides.Second of all t-5 bulbs cover the same spectrum that mh does with the acception of 20000k.kelvins are kelvins.Color temperature is color temperature no matter what bulb it comes from.T-5 has sufficient par to grow coral and clams down to 19 inch's.T-5 vho will do the same down to 29 inch's.I will tell you that I used mh for a few years,and before that an assortment of incandescent bulbs and I can say that I am glad I dont have to deal with them any more.What does the price list have to do with anything,since t-5 ulbs last 4 times as long and cost a lot less? |
