Under Current Recirculating Deep Water Culture (RDWC)

http://groweed.club Basic DIY RDWC:
- fairly inexpensive to build a simple system
- forgiving growing method if constructed properly
- requires some tools
- most home built units are reserved for smaller closet sized or counter top gardens
- for larger plants, more building experience may be required due to practical considerations

Things to Watch Out For:

-leaks can be disaster, don’t build or source materials hastily
-system materials that react with nutrient solution, creating phytotoxic conditions.
-optimal pump (air and circulation) sizing relative to system scale
