All the photos got topped this week. Not too bad growth, but gave a few a bit more nutrients than they could handle, so just water for the next few days. Looks like the one bud on the Diesel may be fertilized. Also a group shot and the main stem bud on the Diesel. The normal looking Studio 54 photo (bottom right) is now confirmed female. A preflower was founded on her yesterday with pistils. lol!
My brother bought a MARS 2000 and was asking me about what power setting and height for seedlings. I landed here because I bet you know. I told him 60% at 6 -12 inches. Thats just a wild shot in the dark. I really like the lights. Thanks for the help.
