im thinking about purchasing 2 of the glow panel 45's, but im only wanting to use them for a few mother plants and for vegging my next set of plants to flower under my 600w lumatek hps! Everyone I talk to says the LED lights are great for mothers and vegging, but they dont compare in flowering with hps lights! Look up mr. blue goo's grow of LED vs Hps on youtube, you cant argue his results! He had 1000w hps at one table, he had a 600w hps at a table and he had a sunshine 600 led at other table, it was a good experiment and he has video updates everyweek thru veg and flower, everyone should watch these videos and see for yourself! I will use led for my mothers and vegging, but you cant beat a 600w lumatek hps for flowering!
