@ Faller200- haha, ya mon. i saw this thread like a year ago swearing by the simple method of water cup cloning, and so i gave it a shot and now its how i do things, although im also currently trying out a cloner bucket (like nitro's)... i dont know how much light tin foil blocks out statistically, but when i hold a sheet up to my lights it looks like nothing is getting through.. and its slightly reflective so thats a plus, but the most convenient thing about it is you can just make a little hole with a nail or something and then plop your clone down in there.
@ ontheDL- yea dude it really is an underrated method.. it takes 2-3 weeks to see any root growth, they basically have to start starving to death and then the roots pop out, but yes.. this method is friggin ridiculously easy. you can get faster rooting with a clone bucket like NitroHarley has, and better mortality rate, but this method is pretty much idiot proof.
