How to Grow King-Size Red Beets

It pays to watch the soil moisture closely if you want large vegetables. I’ve had good results this year using my garden logging system. Actually my vegetables have gotten a little out of hand. I think the cat is a bit scared too :

I’ve been kind of obsessed with soil moisture now that my logging system is up and running. I’ve checked the log a couple of times a day, and when the moisture level was low I ran out and turned on the sprinkler. I hope the large size doesn’t affect the taste too much.

What I did was that I checked the soil moisture graph and when the level was below 30 % I would water the vegetables. Looking at the graph below it shows that I’ve turned on the sprinkler three times during a week (week 27), Tuesday at 09:00, Wednesday at 23:00 and Friday at 21:00:

This process screams for a computer controlled solution and I’m working on connecting a water pump to the logging system to make it a soil moisture control system instead. It would need a hysteresis, like for instance turning the water ON below 30 % and turning it OFF above 80 %.

Another thing I’m working on is replacing my 1-wire Ethernet cable with proper outdoor Ethernet cable. The existing system has worked without any problems for half a year, but I just want to make the whole system even more durable, since the whole point of building this is to free time and energy and instability problems and break-downs take up just that, time and energy.
