I changed to soil for a couple of reasons:
Ease of mantainence is the big one, I do not do anything but ph correct my water to 6.5 and top water...no nutes, just water. I am actually boxing up my thouands and thousands of dollars worth of nutes right now..I love doin all the work on the front end..
Easier on bigger plant counts and especially multi strain, all the plants look killer, healthy, robust, and happy. I was keepin up with (6) 70+ gallon reservoirs before, all with a slightly different setup on nutes and flood schedules..this way is way simple in comparrison.
I can hand the plants off to patients and they can take them and flower them with no hicup or shock or anything. It is very difficult to hand off a hydro plant to someone with little or no experience growing..just add plain water and light seems to work real easy.
100% organic, not a variation, not some in organic materials or nothing, just full on, no questions asked organic love, in a med state organic is king for the med pateints and despensaries...
I live in Ag country so a bunch of dirt and organic ammendments just blend right in out here..
Runnin hydro by the numbers was something I loved when I was younger and it was just me blowing out closets and rooms...success was based on how well you rode the numbers, adjusted, tweaked...kind of a young hard dick approach to it...Now I am more into the energy, the spirit, and love of actually growin the plant, not pumpin her up on roids and see what she'll do if i make her..I like the plant showin me what she'll do not makin her do what i want..I swear it is a completely different mindset for me.
Don't get me wrong, i will still rock a hydro table with the quickness but i don't get the same satisfaction or the same food for the soul that i am getting with dirt right now..
