I have a pretty simple method for cloning that is about 90%.

I just take a 5 gallon bucket (can use one much smaller) and cut a bunch of holes in the top of it to fit the nice little neoprene round inserts that you can buy at a hydro shop (or you can use a pool noodle from walmart for $3). Then i just get the bucket bubbling like it is a DWC and take some cutting so the tips are just in the water. PH adjust the water and just let it go. It takes a little bit but it has worked every time.

Cheap, easy and little to no maintenance, now that is my style right there. LOL

If you want to know anything more detailed just ask away. It works great.

Aero is the best if you are willing to deal with it.

Rockwool is definitely easy but i don't want any rockwool in my system and i hate to buy medium all the time. I try to stay mediumless where possible.
