Yea I like my PlatinumLEDs they do kick out some light, although to be honest the only other light I had any experience with was a four foot florescent fixture with grow bulbs back in the seventies. When I first added the second P300 I was burning plants alive, so I have learned to pegged them to the roof for seedlings and wait for the third or forth node to develope before I even consider moving them down. No one make a reasonable PAR meter so I just check the intensity with my LUX meter. Helps me to find the sweet spot for each plant. Seems to be working, very little stretch so far, even the Grapefruit which is a sativa is staying low so far. Thanks for checking in on us.
Yes they are looking really good now. I can't take credit though because it's my new policy of ignoring them for the first three weeks and only top watering every five days or so. Less is really more sometimes. Thanks
