It’s actually going great! I do have it under lights, though I hope to get the hang of it and eventually set up some vertical systems outdoors to make them more cost effective. Maybe next spring.
Right now my lights, air pump, and fan cost around $25/month to run. Nutrients are remarkably inexpensive (perhaps pennies per head of lettuce assuming they mature on schedule). All said it’s maybe a $30-35 per month hobby which might generate far more than that value in real, edible food. It’s surprising how many plants you can fit in a 1m x 1m grow tent when you use hydroponics.
I’m sure I’ll mess up several times before I get it working smoothly, but I’ve loved the learning process so far.
Before this I got kind of hooked on growing micro greens. It’s such a great gateway to indoor gardening, the results are awesome and it’s very low effort.
Edit: I hadn’t worked out the math yet, but my “break even” would be growing just a few bundles of herbs and 3 or 4 lettuces per month. The system has 24 plant sites so by all means, if I don’t totally blow it, I should be plant-profitable pretty soon! And that’s excluding the micros which develop under the same lights. The cost of micro greens is wild.
