The first year I grew plants from seed, we had no sink in the basement so I learned to water by filling my spray bottle and milk jugs with the trickle from the washing machine. I'd use a turkey baster to water each cell. We're in our first house now, and it has a wonderful old 2-sided deep utility sink in its basement. I use a little tubing thing we got with our humidifier and watering's quite a bit easier this year! I still have to bring each flat over to the sink, though.
I'd really like to try something with capillary matting, though, so the seedlings receive an even amount of moisture, consistently. What is capillary matting made of? Anyone have any suggestions for a low-cost set-up with this method of watering? Thanks in advance for your suggestions -- I know there's a lot of good ideas brewing out there, so post 'em for us!
