Nah you're good, until recently I have never used more than 2 feet of vertical elevation for the reservoir...
If you can have directly next to the plants or just outside the tent it will work. If it's further away you'll need to raise it a bit. The directions on how much are on the tropf blumat page.
It's best to water to full saturation, then install the carrots for "last drop hanging", then close 3 more marks.
Since you watered it might take a couple days for the soil to dry enough to suck the water from the carrots and open the valve in the cap.
BTW they're good to go after an hour's soak, no need to water them for days or even weeks, the clay is not that thick, water will permeate it quickly.
When i set mine I try to be around for a couple days to see if they're responding to the soil drying out so that I can intervene if something went wrong. After they have opened and closed again for the first time, I tend to forget about them.
Best of luck
