Hey yall, thanks for all the LED wisdom! I would love to build a serious DIY setup in the future, but I'm not there yet, ha. I ended up swapping out the fixture I bought for a two bulb T5-HO fixture I was a little sad to return the LED lamp, it was a cool toy- but the new light is almost 5 times brighter and has the right spectral peaks, so I did the right thing and put my children (plants) first, like any good parent. They'll thank me when they're older.
So far everything looks good- I eased them into our first full 12 hour cycle today and nobody's been burned. I opened both windows and have been running the ultrasonic humidifier during the day cycle to buffer any dry heat damage. Here goes!
