Farmers want to turn their fields as often as possible. The same is true for indoor operations. The more quickly you can turn a planting the more plantings you can harvest in a year. And increased plantings equals increased revenue. What farmer doesn’t want that!
There are several segments of the growing process where a farmer might be able to shave off some time. Time to germination, time to transplant, and time to harvest are the three primary ones.
If the average time to germination for a particular variety is 7 days and that time can be cut in half the farmer is gaining 3-4 days on the process as a whole. But how might that be done?
It’s possible to speed up germination time by adjusting variables such as heat and moisture. Experiment with pre-soaking the seeds and temperature variations to determine if there is a way to fast forward the germination process. Create your experiment with multiple sets of seeds that measures the time to germination for pre-soaking versus a control at various temperatures.
What temperature produced the quickest time to germination in pre-soaked seeds? What about the control? What is the deviation between the two?
