Good advice above.
I’ve been growing with these for a while now and most of what I have said can be found around the forums but I’ll bullet point it here quickly.
If you have low humidity use fabric
If you have high humidity issues use plastic
Plastic requires air to grow at the same pace as fabric is the general consensus.
I would recommend the air bases that are newer, clay pebbles have PH issues, and anything else can be messy for re use or waste full. Air will work with an air base in fabric as well, it’s an added bonus some say some say no bonus try it yourself.
Try coco and perlite 70/30 or 50/50, both seem to work, some have equally sucess with straight coco.
Raise your reservoir as high as you can while still being able to fill it ergonomicly (increased hydro pressure is easier to find leaks fast and reduces clogs)
Don’t use organics unless your experienced and under stand the maintenance required.
Ensure you use a silica in your water first, PH below 7 then add nutrients. Silica bonds with nutrients above PH of 7.
Wash your reservoir semi frequently
Use a wave maker or pump on a 15-30min on ever 1-2hr to mix.
If you use air buy a big flat air stone for under the air base they work good.
Dont turn the system on until your leafs stretch past the edges of the pot.
Use minimal amount of connections and taps as possible, these areas is where clogs develop.
After each grow soak all your floats, lines and connections in a 5 gallon bucket or sink full of warm water and a gulg of PH down. Allow to soak all day.
Blow out the lines!! Also ensure lines insides are soaked and not full of air.
Finally, get yourself a water alarm. Save yourself the hassle of a mistake that leads to a flood. Because eventually you’ll forget something and cause a leak.
