I would personally stay away from "packages"
Lets break it down...
1. That light is crap. it will fill that room with heat and kill whatever you grow. you MUST have a vented hood with HPS/MH period
2. Quantum Ballast is great you should get one they offer dimming ballasts too. I only use Quantum for my T5
3. the can filter and fan ya its a filter... and a fan.. get those anywhere... i would suggest
THESE Just wash them with water and ta-da new filter!
4. No growing medium pots etc?? thats a ripoff! try
http://www.airpotgarden.com/ these pots are perfect in every way..!!
5. The tent... well its a tent what more do you need theres a variety of tents out there..they are all approx the same some better quality than others.. personally hydrohut makes a great product but whatever tickles your fancy.
800$ huh doesent sound like a deal to me? hell
THIS KIT is 400 and you get more for your $$$
