I’ve been wanting to get some moisture sensors for a while now but I’ve been holding back because I thought they were going to be difficult to dial in, but that’s not the case at all.
I think these are going to be a game changer for me, yesterday after my p1 irrigation my rockwool saturated around 58-62% moisture content since my plants haven’t quite filled out the 6x6x6 blocks yet just the first set of irrigation was needed for the day yesterday.
During stretch I’m looking for a 25-30% dry back so this morning an hour after lights on I checked my logger and they had dried back to 38-42%. So let’s say 22%.
This mornings I’m going to feed them 3% shots every 15 minutes until saturation then 2 more 3% shots.
62-40=22%dry back. While the plants are being fed the 3% shots they are still drying back a bit so that’s why it’s 3% vs 2% to compensate for the 1% loss.
22%÷3= 7 feeds for saturation then 2 more additional 3% shots for run off.
I was feeding 3.0 ec but my run off was only 3.4 and the pwec was all under 7 so I raised my input to 3.5 today.
This is my first go at it and I’m following dankems schedule, he just updated it last night.
