It sounds like your real desperate to get growing lol. Either would work and both have about the same risks involved. Youv been on this site a while man im sure you know how to do it. Apartment would work but you have inspections and shit. Storage locker would work but checking it all the time...
It depends. If your making Mulbutter/Cannabutter to put into the space cake then it can get a bit smelly. But if your just putting ground up weed into your cooking mixture then it wont smell to much.
I was going to buy this one off ebay. Noble Digital Vaporizers Aromatherapy Device 2007 GIFT - eBay (item 140162698686 end time Jan-25-08 14:48:00 PST)
Ebay is def the way to go if your not looking to spend 300+ on a reasonable quality vape.
