The wet kind.

I use well water and everything is great. If you use city water be sure to neutralize the chlorine.

And I would not trash any clones until you are sure they are not going to make it. But that's just me and my small operation.

No nutes the first two weeks, then 1/4 strength, then 1/2 strength, keep increasing until you see signs of nute stress, then back off a little. That's how much.

Water only when the dirt is almost completely dried out. I know this isn't right, but for any plants I have in dirt, I often just look at them twice per day. When I see small signs of wilt, I know it's time to water with nutes. Otherwise you can tell with a moisture meter, or by lifting the pots to see how heavy they are, or just by sticking your finger in the soil to see if it is still moist.
