Hi..I've searched google extensively and seems im the only onewith this issue. First time trying to grow pickling cucumbers indoors in a container. Plant is now about 6-7 weeks from seed and has reached 6 feet tall. Im pollinating daily with a toothbrush and fan going on the plant 18 hours a day, yet even after the cukes start to grow, they get black hairs along the pricks of it and the flower and shrivel up and die. Its in a 4.5 gallon bucket and im watering with fertilizer every 3rd day 3.5 litres. The leaves are healthy looking, but ckes are not staying it seems. is it fair to say that cukes can't be grown indoors without inviting bugs from outside to pollinate it? Im about to throw the plant out as every cucumber just gets black spots on the pricks and dies in a day. I read that once pollinated, the flower closes up..that's what spome of them do, but then they die anyway.
