My computer is messed up so Ill check the vid out later .. This is what I have so far:

2 400w electronic switchable systems-$210/ea
2 600w electronic switchable sytems-$277/ea

Hydroponic systems from midwesthydroponics.com

Aeroflo2 model 60-$969
Aeroflo2 model 60 extension-$765

Can you guys check out the system and tell me if it would work.. If it would I would add 40 plants every 3 weeks.. How much median would I need for a system like this.. Can you also post an approximate cost of a ventilation setup... Thanks
