Setup a new box, using a fogger. It's an 11l IKEA SAMLA box (in black, to avoid algae growth), with 5cm netcups. Inside is an airstone, and a ultrasonic fogger. I had some spinach seeds lying around, so I put them in some paper and placed them between the hydroton in the cups. Let's see how this works.
I decided to move everything into some metal shelving. Looks nicer and is easier to maintain. Also added a small fan for some airflow across the plants
Setup a small garden with a light. Four plants (pepper, chilli, cucumber, zucchini), in a deep water culture. There's a 30cm airstone in the water connected to a small airpump. The lamp is on a timer, and runs for 12h each day.
My netcups didn't arrive on time, so I of made my own.
