I just picked up the Spider-Farmer 1000 and I'm enjoying it so far. It has more than enough power for a small veg tent, I have it set around 60% right now. I had a question after I bought it and they replied to me email within 24-48 hours, so that is nice. At the setting it is at now, it produces basically no heat. At 100% is does get hot, but nothing that can't easily be managed with a fan and exhaust.
