Vets wouldn’t need to know this, but being my first grow I’d like to state this. I’m in week 2 of veg stage and had just done a drain/fill 72 hours ago. Now 3 days later exact, my water level was half-way below the low-level sensor. No alarm or anything, she still has plenty in there to drink, but I do not think she would have made it a week. I do believe this might have been addressed and that the Grobo team is working on more updates including notifications to remind you to top off as you get later into your grow. Moral to the story, as I ramble on, is to keep an eye on how much she’s drinking-

Low. 20 to 25 % maybe
I have gotten them before. Not on this grow except the bug that says your low when you just drained. I guess each plant is different. But I would everyb2 to 3 days I had to top up my 1st plant

I think its cool everyone has their own system sort of speak. I just never would have thought/bet these plants really drink that much that quickly- but what I’m getting is as you get later into veg, you should be looking to top off after 3 days or so. Fair?
