So I decided to pull the trigger on a budget light for my 2x4 tent, since I need more room for the current plants and gave my SP150 to a buddy. Got the Viparspectra P2000 for $135. Testing it out and it runs a little hot but seems perfectly fine for the price point. Mostly will be used for autos and considering doing a little clandestine pollen chucking project in the 2x4 in a couple months. But for now the smallest/squattest two plants (PTK and Purp x Blackberry Widow) are in there. Just couldn't manage to arrange all the earthboxes in the 4x4 so that I could easily water each.
