Another wave of brassicas, mostly cabbages and cauliflower, are getting a little big as they wait indoors under lights. In recent years, decent fall weather has extended a whole extra month from what used to be. So I’ve been planting later to extend the harvest. (More text to come…)

A day in the sun
I’ve been hardening off trays of seedlings over the last few days, a few at a time, taking them out from the under the lights. Today, they were all outdoors, some for their first taste of the sun. It’s a manual routine, walking back and forth from the light racks with one or two trays at time, then bringing them back in in the early evening. I like it: a clear, simple, straightforward task, and the most important thing to do when you’re doing it. This is also exactly the type of routine that’s perfect for automation, or at least, optimization.
To grow a fair bit more than this year, I would put seedlings out in an unheated greenhouse where they’d stay until transplanting. That brings more convenience and efficiency, and also a few extra concerns. Voles tend to burrow in and munch on greens, so checking the perimeter becomes a thing to do. Daytime temperature in the greenhouse shoots up to 40°C+ (104°F+) on a sunny day, so ventilation is a must. When you open the doors in the day, you have to close them at night against cold and critters, and open them again early the next day. If the forecast is for freezing overnight, row cover placed in the evening and removed in the morning can handle a few degrees below (in a more extreme cold situation, a portable heater fired up in the middle of the night might be necessary).
Then there’s the new super-high winds that started happening around here within the last five years or so, there’s extra concern about the whole greenhouse staying up—mostly not in your control, but you still think about it with every weather warning!
Nothing wrong with scaling up and improving efficiency, while every step to bigger has its complications!
Seedlings in January!
The earliest ever tomatoes experiment begins… Parts of the plan include a proven super-early variety, multiple seedling start dates, and the unheated greenhouse!
Trimming parsley
Parsley, curly and flat-leaf, overflows its 72-cell plug sheet. Time to trim it back (again), so they still fit under the lights. To be unfussy and safe, a quick shear of only 2-3″ off the top literally takes a few seconds and does the trick. Snip-snip-snip-snip-snip! This is what you have to do when you start seedlings extra early, and then wait on the weather!
Transplanting: tiny sections
Transplanting lettuce into the unheated greenhouse, filling it out in small sections to work around wetter areas. The seedlings, waiting for drier conditions, stayed a couple of weeks longer in trays than ideal—now they’re a little floppy and stretched, but I’m confident they’ll figure it out. This first spring, seeing how the ground dries in the new hoophouse is part of the learning curve. Tiny farming!
Seedlings in the sun
Lettuce seedlings get their first taste of full-on springtime sunshine. Next stop, into the ground in the greenhouse. I wouldn’t call this hardening off, some of these are being transplanted later today—tomorrow’s cloudy forecast should give them all the post-transplant adjustment break they need, then bring on the sun!

Seedlings start here
Staring up close at a stack of 72-cell plug sheets in webbed trays. Exactly where most of the transplant seedlings around here get started…!
