Any sources one may cite in regards to your 120 day assertion?
All my sources beg to differ.
This study claims a half-life of 2.4 days in tomato. iicbe.org/siteadmin/upload/6543C0114578.pdf
Note, abamectin is used on many crops. ;)
Instead of using smaller buckets, perhaps get a bigger air pump ;)
Larger sites means more stability in your pH and PPM and longer intervals between maintenance. DWC can get root bound just by filling up with roots then air fails to reach all roots and shit goes downhill fast.
Your 30 amp 240v is split phase so there's 60 amps of 120v provided you have a neutral (4-prong receptacle).
Note, breaker will trip if either leg hits 80% ;)
It is indeed, what you make it. ;) everything you need to know has been provided (hint blower not on floor but up high in the tent blowing heat out the top, passive intake opening in bottom should be where light is not likely to intrude, back side...)
We call it hydroponics.
Any automated watering of soil should be able to detect when each plant needs water and water individually thus not overwater.
Any attempt to automate watering of soil is a compromise at best.
