I had a shelf setup with 4 4ft tubes ( the good growlights) on each level and they were working ok so I thought ..... borrowed a light meter and the needle didnt even move when held up against the light!!!!!
took out my trusty hps 400 watt unit and it will burry the needle on the light meter from 8 feet away!!
after one day under this light ALL of my plants are doing better and the 1200 wave petunias are back from the dead.
so to all of you looking at growing indoors I suggest you just buy a good 250 or 400 watt unit and enjoy.
I have about 50 tubes for free if anyone is in canada and wants them ... just pay shipping
