Thank you!

I am going to try these this year. I had a moisture meter that was always givinge the wrong information and caused me to kill many plants so i am going to try these instead. These look like they could really help me.

I need those! I went to Groovy Plant Ranch today, I wish I had seen this video before I went. :(

Late to the party, but will these work with orchid material?, Or just soil based plants??

I don't know if you monitor comments, but I wonder if you still recommend and use these devices. If so, do you sell them (and the refills) at the ranch? I got a gift card for Christmas and I plan on visiting sometime in January. I picked up an aglomina at a plant swap and it had one of these in it. I think the replaceable sensor material on the one that I have may need.to be replaced.

Hey can these be used in direct sun?
