After harvesting I have water left in my reservoir. Is this normal? If so, how do I get it out. I’ve drained it a few times.
Yes it’s normal to have water left in your Grabo after draining. You have to soak it all up with a towel or paper towels or whatever you can and then using distilled water make sure and clean everything as good as you can so you don’t contaminate where your roots are going to be sitting!
keep your sensors wet please or youll break em
I hold the black drain line down so it reaches the bottom then I tilt my reservoir a bit to get whats left.
You may have to drain a couple times to get it all out .
P.s. I don’t have a screen on my drain line, if you have one then you may have to take it off or use a small cup to funnel the water out.
Don’t I just need to keep the pH sensor wet? I put it in the fluid from the calibration kit and put the cap on it.
I hope you mean the storage solution from the kit? If so your fine with that and the caps!
