I know of a thread you might like to get in on.
The only way to be able to create a topic will be to post reply’s and read through threads. The board has access tiers. By that I mean you must hit certain requirements be met before you are able to create your own thread. I think they just want people to read and interact before they make threads. Be super active for a couple days and you’ll be able to start topics in no time. I don’t have any experience in RDWC. Soil all the way. When I read threads about hydroponics I see a lot more work then I feel is to be gained by going hydroponic.
