with the fabric in the water most of the time, will.it go bad? I want to turn this into a no till planter..
So the mesh pots will constantly be in water
Yes the mesh pots will be in the water. Running no till with knf / jadam practices is the only method to use with sips.
Theres 2 methods of keeping the water good.
1. Air stones. Adding dissolved oxygen to the water prevents pathogens from developing. Roots grow much larger and faster. Really the only benefit.
2. Add a splash of labs or em1. Lacto bacillus will outcompete pathogens. Even if the water does go bad. You can add a splash of labs or em1 and it will kill off any harmful pathogens.
# 2 is what I do. I ran air stones for about a year. Then a pump died in the 3rd week of flower on 2 plants. I was too broke to buy another one right away. I added a splash of labs everytime I refilled the resi. The roots didn't grow as much. But the yield and terpene profile increased quite a bit. I even ended up getting football size tops on a mendo breath f3. Afterwards i removed all pumps and air stones from all the sips. My room has been much quieter.
Also make sure there is an air gap between the water line and the planter.
