I've jumped head first into hydroponics this year, and the last few weeks and months went into perfecting my balcony.
For the minimal space I've got, I have a lot of plants.
For those, I tried to make mostly passive and simple setups, so no spray towers or stuff.
I can post a few pictures if someone is interested, and I'll probably create a new community too for that wonderful topic.
I barely need to use water, my plants are almost pest free outdoors, and they grow twice as fast and big compared to soil. Fits perfectly into this instance!
