Larger Plants

After growing duckweed for a couple weeks, I’m thinking of moving the system to hydroponics so I can grow larger plants. It looks like I need to periodic run a water pump to maintain clear water. The water may as well filter through some rockwool or vermiculite growing plants. Algae and duckweed are listed as some of the top 10 fastest growing plants but this doesn’t mean long term they will sequester the most carbon dioxide. Tomatoes or cucumber vines may sequester more carbon dioxide once they reach a mature growing phase.

This will require periodic replanting instead of duckweed where it proliferates readily and only requires periodic harvesting. Hydroponic planting media is extremely reusable. It only requires some rinsing out before re-seeding. Give me some feedback here or on Kickstarter on what you think.
