as far as rehydrating it imho, I would avoid that like the plague.the reason is is when you harvest a plant ideally you want the pot to be as light as it usually is when it needs water and dont give it any. you rinse you soil with water only and let the plant drink until you wanna chop then you let it dry up since the excess water will tend to lean towards a harsher hit.ive done this many times in organics from fully watered to Zero water and drooping plants dying for water.the plants that wanted or NEEDED water were hands down thee best. excess water will make is burn a little harsher as well as give a less taste although the taste can be alright it wont be where it needs to be imho. happy smoking bro!
