DIY : A high schooler’s attempt at building an indoor hydroponic lettuce farm
Recently, (like yesterday recently) I received yet another one of these free seed catalogs…
Flipping to the back, I noticed an interesting contraption for indoor gardening. Seems like these things are growing in popularity, so I figured I’d share my attempt at how I built my own indoor hydroponic setup!
But first things first, let me clear up some differences between the kits you find in a magazine versus my hydroponic lettuce system. The first is obvious- it’s even mentioned in the title of this article- it’s hydroponic. The reason I built mine to be this way is because it eliminates any need for you to bring dirt into your house, because who knows what kind of bugs, mites, and fungus can be living inside store-bought potting soil! (Not speaking from experience… but maybe speaking from experience.) Also, my system is mainly suited for growing lettuce, though you could totally grow any other type of salad green you’d like 👍.
I plan to write this blog as a series, with this particular post giving an overview of subsequent articles to come. The upcoming articles will cover specifics on a whole bunch of steps.
For instance, I’ll cover the pros and cons of different of grow mediums.
Nutrient tank and bucket net configuration.
Mineral specifics for nutrient solution.
C02/air injections and a raspberry pi based C02 sensor (represented by the three pictures below).
And I’ll also talk about the advantages and disadvantages of grow lights. Both Compact Fluorescent Lights and LEDs work great, and I’ll cover matching lights with different shelf heights.
Thanks so much for reading my first post- hope you enjoyed it! Be sure to follow and stay tuned to know the next time I publish something new. 😁
