Slightly odd looking beets just harvested from the South Pole Station Hydroponic Garden (OC)

Endless questions are totally fine, it’s actually quite nice to have interactions with people off the ice to remind me that what I am doing is actually pretty cool, it’s easy to let it become the everyday mundane.

I grow tomatoes, cucumbers, lettuce, bok choy, peppers, mint, thyme, swiss chard, basil, pumpkin, cantaloupe, watermelon. The lettuce has a hard time sprouting because my seeds are 3+ years old and have dried out too much. We have literally 0% humidity in the station. I tried carrots and strawberries but the carrots wouldn’t sprout and the strawberries won’t produce….. I had a pumpkin plant that was going to be ready for halloween but it died, so that was sad. The plan is to carve a watermelon because those have really taken off and we have 10 small watermelon (we’ve eaten 5 already).

The set up is four systems that recirculate, 3 of which are fed from nutrient/base tanks, one is fed by hand. Two are deeper troughs and two are a system of multiple shallow trays. Not sure what else to say but if you have more questions I’ll try to answer them.

Energy use isn’t really a problem because we have multiple high energy telescopes operating here and a little greenhouse is pretty much negligible in comparison.
