This is a great technique IMO, and was the approach I used for my first grow.
Pros....
Low tech / simple approach
- You don't need all the kit used for ebb/flow, DWC, etc...
Works using a variety of media
- I use coco, but others have used a variety of mixed media with success.
Low maintenance
- Like soil grows, you can water a hempy and leave it alone for days without having to futz with them...depending on your grow environment and growth stage, of course.
Cons...
Not in contention for THE fastest growth rate technique.
- Other, more complicated, grow techniques have a faster growth rate.
More labor intensive than a soil grow.
- Ideally, with a soil grow, all you need to do is water. You've got to mix your nutes and PH with a hempy, and some find that process to be a big pain in the ass.
All in all, I really enjoy this approach because it allows me to get "involved" in the grow like it was a straight up hydro grow, but at the same time it's a chill technique like a soil grow.
