I havent, bit overkill imo if youre not growing large plants. I think you can just let the hugos drain into them, but youll have to watch the hugos dont get too drained by the slab, at least until the roots grow into the slab. If youve got the sensors setup they should take care of that for you and just keep watering the cube as the slab drains it. How often are they getting water? Or do they still remain saturated for multiple days?@rDWCNoob ever used the grodan slabs? i just put the 3 of them ontop of the 6x36x6 slab and idk if i should be putting a drip stakes in or just let hte ones on the hugos drain into it
and youve already got them on the slabs? If thats the case youre probably good to go.It takes about 24 hours for them to dry down 10% rn
That i cant really help with, I dont do sensors so im not sure how they work. Even the term field capacity is foriegn to me but an educated guess tells me it refers to the total amount of water the cube can hold? I would assume that happens at some point, but it could also be due to using the slab. Rockwool holds water in a gradient, so the top is always drier and the water pools a bit in the bottom, where your sensors are. Putting it on the slab is going to change that water gradient and water will pool up a bit in the slab instead of the cube. So, if your sensors are at the bottom of the cube, youre now taking a measurement from the middle of the gradient instead of the bottom? Im just guessing though.@rDWCNoob Yeah I saw that happen in the starter cube I’ll get covers for them next, also , so my sensor is showing my Hugo at 46% wc and getting runoff there which means the roots have developed to where it lowers field capacity correct?
