We are on the cusp of becoming an interplanetary species. SpaceX is leading the current space race, with other competitors following closely.We will see construction of the first space bases on the Moon and Mars in the next decade or two. The key factor to success for the first space colonies is full self-sufficiency.That includes food independence. First generations of colonists will have to consists of gardeners only - since gardening is the essential skill needed for survival there.While many experiments with growing plants on other planets or asteroids can be only conducted on situ, there is plenty that can be done ahead of time. That's where we come in. We are experimenting with growing plants ultra-densely, learning how to maximize production of diverse crops per square foot of valuable growing space. We are identyfying plants that can be utilized most efficiently: every part of the plant is used as food, medicine or raw material for other products. Examples: Moringa and Cannabis.We are studying ways to maximize production of edible/usable parts in other plants - from creation of new hybrids, innovative grafting and rooting techniques, cell-tissue culture and genetic modification. Certain plants, e.g., strawberries, meet the above criterion already. We are not promoting fully-automated agriculture for off-planet plant growing, but rather a mix of intensive human engagement and robotic AI-powered technology.Human engament is essential - gardening has a multitude of psychological benefits necessary for colonists to thrive on a new planet. It will also provide a key psychological connection to the Home Planet.One thing is certain for sure: future colonists will need to grow more that potatoes and spinach to thrive on a new planet. That's why we are experimenting with growing plants from distant parts of the world next to each other. The more variety, the healthier the space colony will be and more resilient. May Humanity live long and prosper! :)
