I dont have problems with Blumats clogging, I just use plain water for organics, and for hydro we have used it with Canna in Coco with no problems related to clogging. Just use products that dissolve easily. I’ve used them for awhile now and they dont clog. But its possible, the discharge tube is small, (3mm). Its part of your daily garden duties to walk around and look to see if they are dripping.
A small “carrot” for 2-3 gallons in coco is what we are running right now. But for the bigger pots we are running the “maxis” as shown in the picture, those are in 10 gallon organic soil grows.
I think 1 blumat per pot will do it, but you can add more drippers if desired. They have distribution drippers if you want more than one part of the pot wet. Or you can add multiple carrots to the pot. But in reality 1 will do the job.
The setup is easy, open the carrot, by unscrewing the top fill with water, then soak the unit in water for 1 day before use. Insert the carrot, connect the hose. Water the soil and when its fully wet open till you see a drop then turn 1 arrow to close it. You just have to kinda try out different settings to get it right. I set it wetter for coco.
In my opinion I still handwater, the “drip” only wets a small portion of the pot.
If you have problems with fungus gnats it can make an environment ideal for them. They will always have a moist spot to go to.
The hose can kink easy, make sure the 3mm hose does not get twisted up after plants are moved around.
