Yeah, the TS1000 draw power is only 150w, but work well. For 4x4 tent, I'm afraid that one SP250 (the prize) is not enough, you need 2 SP250, and the TS1000 continue as a veg light@MarsHydroLED
I am still amazed that this little TS1000 has increased my veg growth by double, at the least, in 2 weeks. This is in a 4x4 tent. This usually took me a month or more with my T8 shop lights.
I would love to have another light so that I can start blooming with a good LED.
Blooming with 600w hps at the moment.
