Summer Science Project: DIY Self-Watering Planters

This summer, in addition to the usual summer-slide-combating schoolwork, we will be attempting two science projects!

Our first project will be to see what happens when we try to grow plants in some DIY Self-Watering Planters! O

ur planters will attempt to re-create the layout of Earthboxes, a self-watering container garden, on a smaller scale to see what happens!  These planters are my own design and we’ve never tried them before, so it’ll be interesting to see what the twins will hypothesize about what will happen, and whether or not it will match up with reality.  (Personally, I think that eventually, maybe the roots will grow out the lid holes and enter the bottom portion, but who knows?)

We used 46oz containers of Low Sodium V8 (it’s higher in Potassium than the regular flavor :D)

Once you’ve planted your seeds or seedlings and watered them the first time, wait until the jar lid has stopped dripping, then CAREFULLY lift out the top portion and fill the bottom portion with water so that when you put the top portion back, the jar lid and pour spout are submerged – be careful not to over-fill or you’ll have a mess on your hands! Then, the water will be wicked up into the top portion’s soil through the holes in the lid.

You won’t need to water everyday (unless your plant is REALLY thirsty or you live somewhere hot and dry and the water evaporates too quickly), but keep an eye on it to re-add water if the waterline falls below the jar lid.

Also if you start getting algae growth just empty and clean out the bottom portion and re-fill again.

Have fun! 😀
