See Our First and Second Prototype!Check out photos of two of our prototypes in action! Prototype 1 Testing Day 0 of planting! Day 6: Some sprouts pop up to say hi! Day 9: We’ve got a forest in there! Day 9: We’ve got a forest in there! Came a long way from the start! Prototype 2 Test 1 Day 0: I love the smell of freshly mixed substrate in the morning! Day 0: Planting done and sensors planted. Day 2: First sprouts appear within 48 hours; timeline similar to prototype 1. Hello, babies! Day 5: Sprouts spreading their primary leaves. Day 10: Beautiful secondary leaves! Day 38: Had to harvest 3 days late, so they’re a little crispy at this point. Day 38: One of my favorite radishes - it’s so cute! Note that I’m wearing gloves to avoid contaminating the sample, not because it’s unsafe to touch. Prototype 2 Test 2 Day 0: Planting! This test is a little different than the others in that we’re testing the adjustment of one of the factors within the system. Can you guess what factor that is? Follow along to see what happens! Day 4: First sprouts! Day 7: More sprouts after increasing substrate water content. Day 10: Secondary leaves appear! Day 17: Opened system to vent and decrease substrate water content a little; stem begins to thicken. Day 24: Opened system to vent and decrease substrate water content a little. Day 29: Final addition of water confirming a new upper limit for water content levels within substrate. Prototype 2 Test 3 - Sprouts Test Day 0: Planting completed. Day 4: First sprouts say hi! Day 8: Sprouts keep growing. Day 14: Sprouts harvested and sent out for safety testing!
