My Season of Hydroponics

If you’d like to try hydroponics in your maker space or classroom it is a great way to get kids to fabricate, problem solve, make mistakes and experience authentic learning. Many designs for simple hydroponic systems exist online with inexpensive materials. The activity is a perfect STEM activity and integrates math, science and a bit of chemistry into a unit or lesson. You also don’t need a lot of room and can even do it on a windowsill!

Sue and I have also moved from a small condo to a ranch home, so these past three months have been hectic to say the least! We are now in the middle of a full scale remodel. As I type this, carpenters and electricians are working. Jolene and her husband, Phil, also moved. The entire Brain Brigade Team has been shaken up. We’re finally settling back into our Brain Brigade routine and it feels good to be back!

My winter season has been devoted to growing my greens hydroponically. I have also just completed a hydroponic strawberry tower. I can’t wait for spring to get here so I can get  the strawberries growing! I will grow the strawberries outside using my system.

My lettuce is doing great but my spinach is not so great. As you can see by the photo, the spinach is in the foreground and is quite twiggy. I think the pH may be off for the spinach. I’ll do some small adjustments to see if it responds. I began the lettuce and spinach about three weeks before transporting them into my hydroponics system. The floating bed has nutrient solution flowing past the roots. My system is about 24 inches wide and about five feet long. It is made of 2x4s with a bottom of plywood. In this box a pond liner coats the bottom and sides and a hole is bored through the bottom on the plywood at one end. The nutrient solution is pumped up to the box and flows past the roots and down the drain back to the reservoir. I’ve been enjoying lettuce all winter, picked fresh right from my basement. It doesn’t get better than that!

This can be done in a classroom, too! We have highlighted some steps in a series on hydroponics earlier in the blog. Start here to begin learning more!
