Plug sheet action

Grow racks

Plastic cling wrap is everywhere. I tried it out last year as a replacement for clear tray covers and it seems to work fine. The method so far: fill the plug sheets with seedling mix, place tray in water so mix is soaked from the bottom up, drop in 2-3 seeds per cell, cover lightly with more mix, soak surface with spray, apply plastic wrap (it sticks nicely to the wet edges of the plug sheet), fill out label marker with variety/date and plunge through plastic (those labels are all that stand between you and variety chaos!), then it’s off to the racks. Now, the trays don’t have to be watered for a week, the mix retains more heat, and you can check moisture by looking at the condensation on the plastic. At first, I wondered about adequate air circulation and whether the fairly closed conditions would encourage algae, but the seedlings emerge on time with no unusual algae problems. As soon as the first couple of seedlings appear, it’s off with the plastic. I re-use the plastic as well, over the 4-5 weeks of seed starting, and the bit of waste in the end, well, I think it’s moderation in everything that counts. (In the top right of the pic, the Vittoria eggplant is tenting its cover, having pushed up vigorously in just six or seven hours overnight. It’s a feisty one!)
