I'm keeping the Kind and the Kessils in the other tent, they still work just fine for me. Just had issues learning how to properly train the plants, and adjusting for the stretch. Last couple of times they grew too tall, and I like Rock Nutrients way more, the plants are way happier. I'll update that grow in a couple of days. The main cola on the Northernlights is 10 inches long and they still have tons of pistils comin in, and none of them have started to turn color on me yet. I was looking to buy the A51's because their cheaper, and knowing they use 5w crees instead on 3ws I know I'll probably get better results. Especially now that I've seen so many grows with them on here. And yeah lol some people do get mad when you drop the K word around here, lmao. I've had the light for about 8 months, every diode still works, so it's still doin it's job just fine. Hey greengenes you know if they have a sale on the at200 if you call? Trying to keep the cost of lights for this next tent under 1k.
