Blumats and soil advice.

I love blumats and I couldnt imagine growing without some sort of auto-watering system. You definitely want to upgrade your main supply line to the flexible red one instead of the black rigid plastic one it comes with.
I use one carrot sensor per 7 gal. pot in amended pro-mix. Attached to each sensor I have 3 drip distributors that make a ring around each pot for 3 drip sites off one carrot. I also have quick disconnect valves for each plant so I can move them if needed and the universal stakes to keep all the hoses and stuff tidy.

i run mine with flexible hydro tubing and put the 3/32 barbs direct into that. building a small and big setup right now just waiting on a couple parts to show up
