I'm looking for trustworthy sites to order seeds from, So far i know Nirvanashop.com and buydutchseeds.com. I've been told that Nirvana is trustworthy, however I'm still skeptical about dutch seeds due to some of their ratings. I'm new to rollitup and need help with a few questions.. PLEASE...
If i have a co2 generator pumping a room to 1500 ppm, with a circulation fan, do i need a co2 extraction fan and/or exhaust fan? I've never used rollitup before and need help with a few questions..
