I don't know the exchange rate but $200 CAD for a used Vortex is too much. You can buy them new for $150 USD at http://www.marylandhydroponics.com/i...ugal-fans.html

4" Vortex is $108 USD.

Look for a thread here by Jamstigator...he has an awesome cab setup for flowering. I'm at work right now but if you can't find it, I'll post a pic of his setup when I get home.
doco Reviewed by doco on . Flowering cab, 250-400W HPS, DIY cool tube and carbon filter Hi guys & girls, I'm putting together a flowering cab to contain the odour. I'll have the actual cabinet in the next day or two and till then I'm going to stock up on supplies. I've never built one before so any advice is appreciated. I think I have a sound plan but if I'm forgetting anything please let me know. The cab is 30" W x 59" H x 17" D. I wanted a few more inches on depth but I bought what I can afford. The cab is this one: Rating: 5
