chasv77answered grow question 5 years ago I am old school soil, so I'll give my perspective.
* Setup for hydro, I fee,l is a little more complex/expensive, and it takes more monitoring.
* I find it fairly easy to recover from mistakes using soil, and can ignore the plants a little more.
* Some like the taste of their buds better, growing in soil. Me as well.
These are just a few.
I have no issues with hydro, per se, and it does speed up your harvest cycles.
If I want hydro grown weed, I buy at the dispensary. :-)
Take'er easy.
