       | Impressive work for monitoring some plants! I hope they don't
       | bite you :)

         | feel the pressure.

       | idea that this is in my windowsill, so the data on sunrise and
       | sunset I could get from a photoresistor. It would also monitor
       | moisture.
       | 
       | This is so cool!

       | just can't win.

         | Just to reiterate what's already been said - don't use tap

         | and he just collects and uses rainwater, as he says tap water
         | will kill them.
         | 
         | Simple waterbutt attached to the drain pipe off the guttering
         | and you get infinite free water for them

       | My carnivorous plants are by the window and I water them once in
       | a while, never had issue.
       | 
       | I thought about automating water supply but even me, a geek,
       | realized it would be a waste of time.
