Well, I built my first ever hoophouse, and I must say, I was pleased. I didn't think it would look that nice. I planted tomato plants (about 300 from seed) the first week of March. Several people made the comment that if I plant them the first week of March that they would be ready by Mother's Day. Everything was going fine until about 7 days into the process. For about 48 hours we had fridgid winds, that tripped a hole in the plastic, allowing cold winds to cool down the hoophouse dramatically. (about 35-40 degrees). It has been almost 4 weeks since starting them, and so far, there is NOTHING growing in the house (except for some moss). I looked around the seeds yesterday, and there are no roots or anything. 3 questions: #1. Was it a complete failure because the seeds froze about a week into it? COuld that have caused the problem?? #2. In a hoophouse with clear plastic 6mil, do I need to have some artificail lighting? I guess I thought that sunlight could pass through the plastic easy enough, but maybe I was wrong... #3. DO I still have time to re-seed 300 plants so that they will be ready for planting??
