Id say pressed pollen is the easiest to make, as it all it involves it collection of kief, then pressing. Bubble hash is a longer process but also worth it by the look of the product. Ive never been lucky enough to try bubble hash yet. But i have tried pressed pollen, which is a really strong high, as you dont need a large amount. The best hash ive smoked was probably hand pressed hash - charras, which is very nice and soft, and burns incredibly well. It gives you a very mellow high, and is great for relaxation.
ahaha, yeah. I've had a piece of that once, only had chance to take a few tokes in a vaporiser though, that was enough. I guess the question was: What is the best kind of hash? also wondering whats a nice plant to make it out of?
If you were going to grow for the reason of creating hash, i think theres quite a few plants that are very resinous, and ideal for hash. Maybe the strain - Hashplant - bit obvious that one. I know theres other though. Have a look round overgrow.com for the different strains, and also some very nice hash photos.
