Blumat Tips and Tricks

Here are all the tips and tricks related to the Blumat sensors 


Do we need to soak and reset the Blumat sensors every time we disconnect them?
No, but it’s important to not let them dry out. If the soil gets too dry it will suck water out of the Blumat cone. You can prevent this by hand
watering before disconnecting.

In medium pots, is it better to add a second Blumat sensor or distribution drippers?
If you’re only at the point of adding one, it’s better to use two Blumats as insurance. If everything is dependent on just one and
something gets clogged, crimped, or stuck; your plant wont get any water at all. A second sensor acts as an insurance policy.” In larger pots
though, it’s better to add distribution drippers rather than a 3 sensor.

What does “Tropf” mean?
Tropf means drip and is a way of differentiating these from Blumats designed for houseplants. (Blumat is just a made-up name without any
special meaning

Do you adjust Blumats with distribution drippers differently than ones without them?
Make the adjustment without the distribution drippers attached and start with only a one-arrow turn down instead of 1/5-2. We recommend the
first dripper to be 3-4” from the Blumat carrot.

Can you use PVC or another material and convert regular and Maxi Blumat sensors into longer versions?
Yes, you can make them up to about 19”

Do you need to soak the Blumat bottle adapters?
No, since they have a constant pressure, no need to soak.

If Blumat Juniors get air inside, do you need to re-soak them?
No, you can just refill with water.

What is the minimum pressure required for a Tropf Blumat system?
To be safe, we recommend at least 2.9 psi.

Can I use Blumats with tropical and desert plants?
Yes, you can use Blumats with both tropical and desert plants. The best way to adjust for the differences is to extend or decrease the
distance between where the Blumat drips and the sensor. The further away it is, the longer before the water will turn off. So for tropical plants, it's
best to have it further away (4-5") and for desert plants you would want it much closer, maybe only 2-3." You can also adjust by turning
the screw on the top.

Does it matter if the 8mm feed line is above or below the drippers?
No, it doesn’t matter. Pressure is only dependent on the distance between the water level in the reservoir and the point where the water comes
out of the Blumat sensor or dripper

How do Blumats work for plants in hanging baskets?
Putting Blumats in hanging baskets may be one of their best uses. In high-wind, hot environments it’s almost impossible to give plants enough water
with any other method short of watering by hand many times a day. Hanging baskets are also more vulnerable because easier to overlook and forget
watering cycles. And if forgotten, the surface easily crusts over and when you do water, it tends to quickly run off and fall into your face!

Blumats and Organic Tea's / Nutrients
Some nutrients are not recommended to go through the small Blumat tubing (very thick nutrients such as molasses), but you can still use them with Blumats by pouring the liquid solution around or near the Blumat ceramic cone. The Blumat will account for the extra moisture and will discontinue watering until the soil reaches a drier stater. Do NOT pour the solution on top of the Blumat plastic head, or you may risk the acidity burning or breaking the sensitive internal plastics.
