love that table

definitely, cant wait to see it

so the problem with these is the board breaks down after a while becuase it gets into the circuit board not to mentioned the copper affected by the minerals in the soil and or nitrients

yea i used those in my food garden, i opted not to use them on my indoor plants because they would likely splash and make a mess when trying to get them max coverage

aint that the truth

love the rain idea

also early on you said sprayer, what type of sprayer are you talking about

if it puts out a voltage range it could be adapted to arduino... do you have a link to your specific model

i would love to see these, i have considered doing something similar on a 3d printer

you would want a probe or some sort of controller that is in a Normally Closed or Normally Off state... but yes it could be troublesome and definitely want a watchdog circuit

yea those probes still require someone to physically look at them

i moved away from smart plugs that are off the shelf becuase they require internet, which is not to say they dont work they just leave room for error

this is what im using now... https://www.vegetronix.com/Products/VH400/ from the perspective of a small home grower the cost to buy a sensor for each plant might get prohibitive as well as a commercial grower especially when you are talking hundreds if not thousand of plants...

you can adda flow sensor to be sure water is flowing

thats pretty much what im after, something the average home user can use and be scalable for commercial applications

my thought was for example on a 4x8 table you could have probes in an average-like plant to determine the average dryback rates and determine watering based on that

i have thought about having solenoids at the individual plant level but i think that would over complicate things... my thought is plant groups by strain and age... as they are likely to use the same or similar volume of water

as for for controling water flow thats easy, there are a ton of single solenoid setups, floraflex is a great example of that... this is one that i have considered using...

i have been looking for single manifold where i could control different ports but have had no luck... the best idea i have come up with is using flow regulators. What are you trying to do? are you using the same source but want different output volumes/times?

i may or may not have a 3d printer as well lol... but yes i am working on the auto watering... the goal is to water based on water content levels, preferably determined by probe monitoring.
