Q: Do I need a bigger Level Controller if I want to add more pots?
A: No, the same Level Controller can be used for up to 48 pots but it does make maintaining the nutrient much
easier if you have fewer pots on a controller. 48 large plants might need to have the reservoir topped off twice a
week.
Q: Can I add more than 48 pots?
A: You can, but it’s not a good idea. All the water goes into the system through a 3/4 inch hose. A system with
100 pots could take an hour to fill and drain. The longer the plants are submerged, the less oxygen the roots get,
slowing the growth. If you need that many pots, you should run two Level Controllers.
Q: What size plants can I grow in the Multi Flow?
A: Anything up to about 5 feet tall without some other means of support. If the plants are supported with a
trellis, the sky’s the limit.
Q: The bottom of the Controller has about two inches of water left in it after draining. Is this normal?
A: Yes, the pump will shut off when there is about 1-2 inches left in the Controller. If not, the pump runs dry
and it may need to be primed. The water level should be just below the inner pot.
Q: Can the pots or reservoir be placed higher or lower than the Level Controller?
A: No, the reservoir, Level Controller and pots should all be on a flat level surface.
Q: Can I grow different types of plants in the same system?
A: Yes. All the plants must be able to use the same nutrient mix and have similar watering needs.
Q: Some of my pots don’t fill up all the way, or drain down to the one inch level, what’s up?
A: If after 15 minutes of filling you still have some pots that don’t fill all the way, there is probably an
obstruction. Some common causes of this are, a rock in the tube, a kink in the tube, a rubber stopper left in or
the roots have grown so large they clog the tube.
