Blumat watering system

Hi there.......Had a question for you. I have been setting up my indoor Blumat system (pic attached) this week......... just one Blueberry strain in a 7 gallon pot with an organic supersoil (from a local Canadian company called Stepwell Soil). Have one standard carrot and 3 drippers (and the moisture meter). It took a few days after initial set up for the carrot to start releasing the valve and flowing water to the drippers. However i am struggling a bit with these 3 drippers and getting them dripping evenly. Have you had any issue with these drippers?
They are not supposed to drip evenly if properly set. I use them without those dripper thingys; just the one small hose through the carrot. You could use two or more carrots for that container; the moisture will be regulated only in the one spot where the carrot is located. I put 2 carrots into each 7g smartpot; 3 in the 10g. You still even may need to hand water as needed to avoid dry spots. Make sure the reservoir is elevated high enough for perpetual gravity feed; I had to rig up a pump to fill my res bucket because it’s up so high...set on top of an old tv cabinet.
The carrots are supposed to be set once and then adjusted as needed over the next few days or so. Once properly dialed in the root system pulls off moisture as needed; the drip increases slightly as the soil becomes drier. It does not run indefinitely; requires re-adjustments every couple weeks. Sometimes; especially when the system reservoir runs very low or dry, you’ll need to re-soak the carrots again and reset the drip.
Blumats are great for going on vacation but they don’t keep working automatically forever. The problem with “flooding” occurs when the inside of the carrots or the soil itself becomes too dry and they begin to pull more moisture which causes a runaway drip effect. You try to increase the drip valve to adjust it but sometimes you overcompensate. I’ve emptied my reservoir overnight this way more than a few times.

Great info......thanks......... I was thinking about adding a 2nd carrot to my 7 gallon and not using the drippers at all........exactly as you suggested. I will do that tomorrow and monitor accordingly. Cheers :-)

Never used dripper either. Two carrots per plant in prepared trenches in ground. As with anything, just keep an eye on things. I have a 275 gallon tote that I use as a reservoir. I have that connected to a 24 volt pressure pump, attached to a two gallon accumulator tank (pressure tank). Same type of setup an RV uses. This keeps the system pressurized to 45 psi, which is reduced to 15 psi as required by Blumat. Always prefill carrots and soak overnight before placing in ground. Then you have to dial each carrot in. Takes a bit of patience. As this is an off grid hoop house, conserving water is a top priority. Blumats deliver the amount I dial in at each site rather than just running on a timer. I am running 1/2 strength Jack 321.

I run netafin in my raised vegetable gardens where water availability is not as big an issue.

Very good info. Thanks a lot. I am going to stop using the drippers and set up my 7 gallon pot with 2 standard carrots and a Blumat moisture meter.

Been running them for years. Works great for water only grows but there is a learning curve. It takes some trial and adjusting to get them to flow correctly and it can turn into a total nightmare if you let the reservoir run dry. Keep the bucket elevated properly and try to set all the lines at the same height. No “roller coaster” humps; may need to zip tie the lines to keep them even.
Do your self a favor and order an extra inline shutoff valve for stopping the flow for maintenance or transplants. Makes for less of a mess in your grow area whenever you need to move things around. Once you put in the carrots mobility is limited. I use 2 for every 7 gal pot; can get away with one per container under 5g. I added a pump to a water supply bucket so I don’t have to lift anything to fill up the res. Can even be put on a recycle timer to top it off once per day for long term vacation watering.
Do you suggest looking at any youtube videos in specific or pages on the forum to look at for tips? I am thinking of running a system similar to you. I have 2 5x5 tents with about 20 plants in each.

Not much to it; fairly simple set up and the blumat website contains helpful info. Never looked at videos about blumats myself but I’m sure they exist. You can probably use a single reservoir for both tents but a standard 5 gal bucket might not suit your needs for that many plants. You will need at least one carrot per pot & possibly two depending on size. Could be significant initial cost for a 20+ plant system.

Thank you sir . Yeah, price is exactly what I'm looking at. And I feel like it's over priced all except maybe the sensors. My uncle suggests try making a system from scratch blueprinted of blumat. However. The piece I don't know how to replicate is the drippers [the carrots]

Tropf got their carrot dripper design locked down which is why they can charge what they do. I have a fairly small system; using it only for my bloom room plants right now but it was a pretty big nut to swing to get started and then I had to add more carrots. Tryin to keep plant count down to 6 flowering at once max but perpetuity may force crowding the space.

Right. The idea would be to get the rigging down from home depot and then the carrots from them.

You should just hand water the Trompf system has the potential of flooding your grow. My buddy had it happen in a house he was renting and lost his deposit. ¯\_(ツ)_/¯

AutoPots are made of really shit cheap plastic and their reservoir is now a trash bin in one of my grow rooms. I had a horrible time with their system in coco/perlite 50/50 blend. If it wasn't a tray failing to water properly the roots were bogged out with water and yield was impacted greatly. You also can't run as many supplements, teas, etc. because it will clog up your system.

I think AutoPot, BluMat all this type of stuff should only be used if you MUST auto water and have no other option.
I duno how you could flood if you're looking at your grow. I've never had a full out runaway I've caught it in time. Plus I put a pond liner on the bottom for insurance. There's ways to make sure you won't flood.

I found a guy on YouTube that makes the blumat system a closed loop system for equal distribution of water [and ease I'm sure]. Each line coming out of your res has a shut off valve too, along with a bleeder valve to expunge any air.

Has anyone had experience making their own system? I consider it "grand master" knowledge for sure don't get me wrong. And I'm quite novice. But..man. .this gravity system seems very easy to manipulate and save you about 300 dollars or more.

Also, thank you guys for the responses

People discuss different looping setups in that thread that was recommended. I use a small pump and a pressure reducer valve, but most others have gotten crafty with gravity.

The one posted from jjgrow? For sure I'll take another gander. My uncle also brings up considering putting in air stones or stirs to the res since I'm planning on have a reservoir big enough to accommodate 40 plants. [Or split to 20x20] He believes the water can stagnate. Have you had problems similar?

Get yourself a wavemaker or two. Some people use small pumps, but they can raise the water temp quicker if that's an issue. Air stones supposedly raise the ph quicker, and I hate their rigid hoses.
