Dont trust those for your babies. They will 100% over water your plants. And youlk have a few bottles of water in your tent on the ground. I have to work my schedule around my garden. If you want something thats going to work forsure check out tropf blumats. You can get them on amazon or from them directly. Top quality. http://blumat.com/en/?m=0
You can also set pots on buckets of perlite or whatever and kinda make a SIP. Sub irrigated planter.
