Ah ok, that's the info I was looking for. As said I don't have a few foot height to play with given the container location, only 1 foot. But if the carrots work just like a free flow pipe then that's fine as I've been using the same singular res setup only with custom halo drip hoses. They do the watering slowly over an hour period or so.. but they won't keep a constant moisture level over the days like blumats, with obvious added bonus.
Would you say the volume of water is sufficient for every other day fill ups (roughly 3 gal pots). I read they use less water with blumats so hopefully. Also any concern of the 5L volumes sitting over the 2 day duration?. they will completely out of light and direct heat.
