Outdoor Sour Diesel Auto - 1st time

Day #4 update I'm shocked, amazed, astounded, thankful and just plain happy that the cold and rain didn't kill these babies! I saw the temperatures get down to 47f after that cold, rainy day. I have checked on them and took some photos today and they're appearing to bounce back! ============= Day #2 update - Cold and rainy. 57f and yuky out. Glad I used the cups over the seedlings. I checked them and a few are breaking the soil in spite of the rotten weather! ============= Bought other seeds from North Atlantic Seed Company and these two sour diesel were the "feebies"! I asked about what breeder they came from and their *guess* was Seedman but I don't see a match here, so I am listing them as being from fastbuds as these other seeds I ordered were. I am growing these along with two other strains. All were dropped in water on a Saturday morning, soaked for 12 hours and then moved to damp paper towel in baggies. I am planting them on a monday afternoon. (Of my seeds, these were the smallest seeds and had the smallest tap root at the time of planting.) For each variety, one seed will be in a 5 gallon smartpot with happyfrog potting soil and the other seed will be in natural soil which I dug out to to roughly 5 gallon size and then loosened the soil and mixed about 1/3 the volume with compost. Not sure if the plastic cup is needed, but I'm giving it a try. I drilled two 1/4 in holes in each cup. (Newbie here, so I am making some of this stuff up as I go!)
