sorry, the earth is at its closest, to the sun, in our winter months, we are currently moving further away from the sun at this point. it is how the earth rotates on its axis. so even though we are closest to the sun in our winter months, our silly egg shape and tilt points us away from the sun. we tilt, or should i say, we wobble, back toward the sun during our summer solstice, though the sun moves further away/or we move further away. (when God made the earth, he said let's make it in the shape of Burning Colon's head and some days he will tilt it to the left and some to the right).
i am thinking cloud cover may be helping you along right now or high moisture content due to southern storms. we are in a la nina year, the last one was 2008 - that was my best growing year, why my tepin even produced pods(that was the last time it did, i am hoping this year it will deliver again).
for 30 minutes today i was able to put a few of my plants outside, but it is still too cold and we just finished another snow pounding but i am going to put my plants in my dodge caravan as during the day as it warms up quite nicely. thinking, with the tinted windows, void of direct sunlight, the higher temperatures should create a nice greenhouse effect. can't believe i didn't think about during that in past years.... it just hit me today.
hope you have a great growing year.
