The first key factor is age. Seedlings need moisture and humidity. Their root systems are too small to draw up enough water if their leaves lose too much to the atmosphere. However, too much water/humidity can lead to damping off (pythium). So careful monitoring with a hygrometer (humidity monitor) and ventilation to keep the levels between 50-70% is desirable.

Sown seeds need plenty of moisture. The water content of the seed needs to be about 70% for a chemical process to start. The three bacteria used in the study were: Bacillus mucilaginosus, Bacillus megaterium and Pseudomonas fluorescens. The researchers tested other bacteria as well, but those did not produce the same beneficial effects. A plant cultivation system on the moon could help meet long-term food and oxygen requirements for human crews, Xia added. Plants produce oxygen as a byproduct of photosynthesis, the biological process in which they turn sunlight into energy.

Plant Magic – Soil Grow

MENDOZA: It doesn't have organic matter, and it's also missing some certain macronutrients that contain nitrogen, phosphorus and sulfur. More exotic seeds have dormant periods that can last years. Or require unusual conditions to break their dormancy such as fire. MENDOZA: To maybe not be Mark Watney - I'd prefer not to get stranded on Mars - but to be an archetype, inspiring people to learn more, and you really do a lot with available resources. CHANG: But he's not quite done with the project. Pea plants take about 10 to 12 weeks to fully mature, and Mendoza's are almost there. A special blend of Sphagnum Peat, Fytocell Foam, and our unique Organic Growth Stimulant. Plant Magic – Soil Supreme makes for a superior growing medium that always yields the best results.

MENDOZA: All of the plants that are growing right now are exhibiting flowering. If they haven't already started growing pea pods, they are flowering, which is awesome. To make sure that your Soil Supreme is performing well, simply water regularly and make sure that you have sufficient drainage so that it doesn’t become too saturated in water. It’s never been easier to grow strong, healthy, and robust plants. SHAPIRO: Mendoza mixed simulated Martian soil and frass in different ratios to see what best supported growing English pea plants.They make a full range of both mineral and organic origin, with a range of matching boosters and additives to boot. Not just for Soil
