After the germination process finished, we started by planting the seeds in a home made mix of medium. We used 60% soil, 30% coco coir and 10% perlite to make a nice, airy grow medium for our plants. The first few day's we kept the plants inside because the temperatures outside were to low (11 - 14 degrees Celsius) and we were afraid that these low temps might damage the plants. Currently the plants are outside as the temps are higher (16 - 18 degrees Celsius.) The plants get about 6 -8 hours of sunlight, as the temps drop down too low in the evening and are still too cold in the morning. I might expiriment with giving the plants 10 hours of sunlight by putting the plants outside a bit earlier in the morning (around 10:00am), as the weather seems to get better every passing day. I hope this won't stunt their growth. Only 2 of the 4 plants are showing signs of life as only 2 seedlings are starting to come out. The 2 seedlings are about 0.8 cm tall. We hope the other 2 plants will follow soon.
