My test is about to restart, though I am not looking at which light(s) to use. I've settled on the 13 watt, 225 bulb Red/Blue LEDs. I sowed some tomato seeds Thursday and the majority have sprouted. This test will be to focus on how long it takes the plants to reach 1) transplant stage and 2) Market stage.
This winter/spring I want to raise ~700 or so toms for sale. I want to have them ready by the first weekend in May, which includes having them hardened off, at least to a point. I also want to transplant about 200 or so of them into 3" or 4" containers, for those fools who really think bigger is better and are willing to pay for them.
I will add at least two weeks and maybe three weeks to the grow time, as they are going to grow much better in 70-85 degree temps than in 60-75 ones.
One thing that impressed me was the speed the seeds germinated at. I sowed 12 seeds Thursday evening and have 50 percent of them up. Toms like - make that - have to have, a very fine media to sprout.
