I bought a "greenhouse" tray with 72 jiffy pellets the other day at Wal-Mart, put in on a shelf inside the house, and it kept all the pellets/pots constantly moist. Outside I have dozens of seedling trays. These I made up with std non-perforated 1020 plastic trays and 6-pak deep plastic seedling pots. It seems to me that rather than put a little water in each tray so the 6-paks "float", it would be better to have those felt-like pads in each tray, similar to the felt pad in the store-bought greenhouse seedling starter tray. But a Google search hasn't turned up a source for the wick pads...so maybe growers don't use them?
Ideas? I am trying to start enough seedlings to plant about 1 acre...my time for gardening is very limited, and I want some system which I don't have to water the trays of seeds or seedlings daily, or even check them every day. I.E., I could be sure that all the 6-paks will have proper moisture level for a few days without attention.
I've been using both for years for all my seedlings. I also use it outside with mail order and other small plants until I can get them into the ground. I use a platform which raises the matting up, and fill the trays with water. As a weekend gardener, I find the system invaluable.
These are the two best deals I've found on complete systems. They are both very sturdy. The ones from Gardener's Supply are a little bigger. I use them outside in a mini greenhouse in the spring, and sometimes on the patio for extras, especially if I'm going to be away for a while. IGC sells small 1 1/2" PVC sections to raise their grids.
Pfg -thanks so much. This spring I purchased several of these trays from Gardener's Supply
and they sure make watering seedlings much easier. Unfortunately I planted the seedings
in a MG mix that included fertilizer and the mix turned out to be much too dense. I wasn't
happy with the growth rate. Next year I plan to use Pro-mix and add the fertilizer myself.
I'm a newbie at growing plants from seeds but I'll keep trying to get it right.
This year in addition to the peroxide I added Superthrive to the water. It's a rooting stimulator- worked really well. I used Scott's seed starting mix which has fertilizer in it, but seemed ok. Then I got excited about coir blocks, seemed very convenient to store and use, but in the end was disappointed. I think I lost some seedlings with it, the roots looked burned somehow. I've read somewhere here that it can contain a lot of salt and should be flushed out. But my whole reason for using it is that in the winter I'm working in a city apartment and the coir blocks are easy to deal with. If I have to start rinsing and rinsing, it can get very messy. Mail ordering gets expensive, bringing in big bags from the country in the fall before we close the house requires too much closet space. Locally I don't have a lot of choices, so basically I'm stuck with whatever Home Depot sells. I guess next year I'll stick with Scott's.
I use cotton flannel as a capilary mat. You have to wash it yearly (or more likely, throw it away).

Don't they flood and drown roots when it rains?

I'm about to set up some fine-spray sprayers or misters on a drip irrigation system with a timer. But I'm wondering which kinds of sprayer to use. I would like to avoid "misters" since they are more expensive and are supposed to clog easily.
