One hole two inches from the bottom is most common - I would go with that. Unless you are using organics (which is generally not recommended) there should be very little organic material in the water and with all the oxygen available the anaerobic bugs are not going to get a chance to grow so rot is not be an issue. I use hydrogen peroxide in the water to further mitigate this - it kills anaerobic bugs.Ok I understand. So I will just use a regular bucket and cut the holes in the side. Sorry for all of the questions. But I have never heard of a hempy bucket until recently. But ever since I have heard and seen this method, I have been in love with the hempy bucket, lol.
Ok so my other questions are this...
1.)How do you know when all of the water is used up at the bottom? Like how long does it take take the plant to use up the water in the reservoir?
It seems like water just sitting at the bottom would cause root rot since it is stagnant.
2.) How do you deal with salt build up? I would also think that with the reservoir salt build up would definitely become a problem over time. How often should I flush with plain water? Every other watering? Or every other few waterings?
3.) Some people say the cut the holes 1 inch from the bottom, and others say that they cut the holes 2 inches from the bottom. Which one would be better? Does it make a lot of difference?
Hahahaha..Dillinger you read my mind. My next question was going to be about Hydrogen peroxide.One hole two inches from the bottom is most common - I would go with that. Unless you are using organics (which is generally not recommended) there should be very little organic material in the water and with all the oxygen available the anaerobic bugs are not going to get a chance to grow so rot is not be an issue.

Watch your plants - you will learn when they are thirsty. The exct timing of when you water is not an issue as long as they do not get too dry. You cannot over water with hempys. Its pretty easy to flush them if there is a nute or ph problem. When you water make sure there is sufficient runoff so that the solution in the reservoir has been thoroughly exchanged.
