Drip feeders on Grodan slabs

[PLEDGEY]

Any one running drip feeders on 1.2m Grodan slabs?. If so, how often do you have the pump come on, 2,3, 4 times a day? and what is the duration it's running for when it is on, 1,2,5,10 minutes?. Cheers.

In Hugo blocks I went by weight as to how often they came on and then long enough to displace the stale solution with fresh O2 rich solution.

6x6x6 blocks with four 2gph emitters per block.
pump runs once a day up to 3x a day, feed to run off each time. I go 10% plus.
time can be from 4 to 7 minutes each depending on growth stage and number of feeds per day.

what made you choose the slab form of rockwool?

Been using Grodan for years. I was just curious as to what others were doing. I'm basically doing the same sort of times/durations as you are with the 6's. I check the run off and adjust accordingly. I first started in soil, literally dirt from the garden and some Durban poison seeds that I got out of a bag of compressed crap, it was mostly sticks, if you saw it today you would laugh them down the road for selling it.
