I really like the cucamelons! They look great, have a really satisfying crunch and are wonderful for pickling.
Can't really complain about my system, I haven't had any major issues so far. I thought about doing an aquaponics one but I would have struggled with the space, especially if I wanted to run 20+ buckets on it; I would have needed lots of fish I suppose. It's my first hydroponic build as well and I didn't want to complicate it too much having live fish in it.
It's not a deep water culture, I'm not quite sure what category it would fall under. It's my take on the dutch bucket system. The buckets hold about 2 inches of water at all times and are watered on a 15min on, 15 off schedule during the day. I've got explanations for the system here and a bit here.
Cheers!
