Update:
Enough stretch has finally occurred that I was able to prune out some of the dead/old undergrowth. Cut a few shoots that were just big enough for me to attempt cloning them, but kinda doubt they'll take root. Even if they don't, I've got the 6 others in veg that I can cut from later if needed. Got an unexpected check the other day, so will be purchasing an LED this weekend! Think I'm gonna go with the HSS light, both because of my height restrictions and wanting to try something that not everyone is using. I still plan to get a Spectra 180 this fall/winter, but it's too far out of my budget for now unfortunately. I'll put up pics tomorrow, marking the end of week three.
