you mean a table like this
http://diegartenfrau.blogspot.com/2010/02/growing-seeds.htmlI made one a few years ago, it has been working pretty good for me.
I think your plants should do good with this timing of light and dark.I am not sure what the formula was, but I had mine on for 14-16 hours.
This year, since my sun room is much too cold to start seedlings at this time, especially peppers and eggplants, I also with the help of my husband (I could have it done myself, but he always wants to help with these manly things >lol< so sometimes I let him), built a warming tray with that foam stuff coated in shiny aluminum and these Christmas rope lights. I am still waiting for my thermostat to better control it. I haven't planted anything yet, first I wanted to se how warm the soil in the pots will get. I think it will work fine I measured about 73 F today. As long it is as cool as it got again I don't think I even need the thermostat.
I am trying to start my tomatoes, peppers and eggplants earlier this year, bigger plants in the NW I heard will produce earlier. The trick is just to keep them warm and transplant to bigger pots as the grow. Otherwise I only am starting seeds I will be able to plant out early season, before they get too big for their pots. Where in the PNW are you located? Our official last frost is April 24th, but since we have moved half a gardening zone higher now due to global warming it is unofficially now April 15th so I am adjusting my planting dates.
I had the same problem with my row covers last year, I did have hoops to hold the row cover but neighbors cats shredded the row covers to pieces. I think when it is a bit windy they move in the wind a little, even they are clipped to hoops and the cat's think it is a fun toy to play with. I was so mad. I have lost a lot of veggie seedlings to neighbors cats digging in my beds, not to think about the presents they leave in there. I really think cats do not belong outside, they should be in the house.
I also have one bed I kept free of plantings, but now I am thinking I might use it for growing more peppers and eggplants, I decided to grow a few of my older Hybrid seeds and I might try to grow them out to OP seeds. I'll know in a few years if I succeed>lol<
I started a few years ago saving the seeds of my salad and endives, then I added Tomatoes and peppers. I am still a novice at it myself but I really want to learn to save all my seeds, as much as my yard allows since so many of the heirlooms are disappearing thanks to Monsanto and Co, if we want to preserve OP seeds we'll have to do it ourselves I am afraid.
Some are more difficult to save and some are almost impossible to save on a regular sized yard, since they cross pollinate each other for 1/2 a mile or more.
I have several compost bins and I use that, we also added chickens last year and they give me good fertilizer. My beds are filled with gardensoil from our local compost facilities, plus my home compost/chicken compost and finished off with mint straw. Which I learned last year is supposed to be the cream of the crop for gardenbeds.
I also add some home mixed organic fertilizer and in between I give them diluted Fish fertilizer and Kelp water.
Often I forget to fertilize though, one of the things I need to improve at >lol<
I wish you too a successful growing season
