well I have been doing alot of reading about the blumats, so ill share a few things I learned so far.
1.Pond liner/Trays in case of runaway
Just learned this yesterday,originally I used a plastic sheet for painting and what not on the the floor in case of a runaway, suffice to say for a week that I used that method I was extremely paranoid of it flooding out so yesterday I read to use a pond liner duh! Perfect comes in all different sizes, so I had to take all my plants out yesterday to install it(definitely not as worried if I get a runaway) but thanks to the above post about the quick connects it was much less painful thanks water proof they work great for taking out plants already hooked up,but if you don't have the the quick connects you can just tie a knot in the 3 mm hose that attaches to the carrot.
2. Quick connects or knot in the drip line
having these really makes taking out a male or doing work on your garden heck even putting in a pond liner...
3. Extra drip line
buy extra 3 mm drip line so you can move you plants around some people make them 3-4 feet , mine are only between 14 - 30 inches id say, was nice I just connected the quick connect to the line they supplied so it wasn't a waste(the tiny drip line it comes with is pretty useless)
4. T with shut of valve at end of line/farthest point from res
this way you can let out air and debris, i use a loop with two through hull adapters and a shut of with a T at the farthest point in the loop from the res this way ir equalizes the pressure and if something goes wrong on one end it can still get water to the rest
5. Bigger pieces of perlite can throw off the sensor
You should dig a hole where the blumat is going to go and fill with pre moistened peat/coco/ewc, i did this then watered around the blumat after installed to ensure it was nice a wet around it
6. T after hull adapter
I put a T fitting coming out my res with one ends hose pointing up to nothing to let out my air bubbles in the line before they can become a problem
7. Nutes
Well i use organic soil with just water and this is the best course because its straight water, but from what I've read organic Nurse no good, only a few salt based nutes can be used you will have to look into which ones exactly
well that's all i can think of right now if i can think of anything else ill stop by
