As with any genetically modified organisms, keeping the iGarden plants safely contained is of the utmost importance. We developed a ‘fence’ system which ensures that all the plants stay inside the iGarden, preventing the spread of modified plants beyond where they are wanted.
The genetic fence operates by positive containment, meaning that the gardener chooses a fenced area in which the plants can grow, and outside of which they cannot. This ensures that any accidental spillage of iGarden seeds will not result in unwanted plant growth or spread of the modified genes.
Our fence operates by mixing a ‘fence compound’ into the water used for the garden during the first few weeks after planting. Once the plants have established themselves, the garden can be watered without the fence compound until another round of seeds are planted. The fence compound, a small molecule, is very safe for people, animals and the environment.
