Hilariously, I was shopping for seed starting gear last year and reading the comments and trying to figure out why there were like 30 people complaining about pinprick light escaping through the grow tent zipper, and my husband had to explain that this is for people growing pot plants in their bedrooms lol.
Yeah, it turns out that the entire
Cannabis genus is
incredibly sensitive to light, and this can affect things like sex determination, and how much of the various psychoactive compounds the plant produces . Yeah, hippies like cannabis because it gets them stoned, but it turns out the agricultural departments at universities also really love the plant. The plant is super sensitive to envronmental conditions. Things like overall light levels, light timing, light spectral balance, temperature, humidity, and minute changes in soil nutrition, can have huge effects on how the plant grows. That makes it a fantastic research model for when scientists want to ask questions like, "Do the different colors of light affect how the plant grows, and if so, how?"
Of course, we have like 100 frost free days so we need to work smarter, but I have to remind myself lest I spend my day open mouth crying outside in a blizzard.
This year I am going to build a little in situ high tunnel for the peppers, tomatoes and a couple of melon plants. I was able to grow the plants last year but the peppers especially needed just a few more heat units to thrive. The tomatoes did great in the open but I’d like them to ripen a bit earlier when I can get help processing them lol.
Something that might be worth checking out for extending your growing season is the
Wall-o-Water. I found out about these when combing through university Extension Office websites for information on tomatoes. The Wall-o-Water works because water, being clear, permits light through to the young plants, while simultaneously getting warmed up during the day by what little sun it does absorb. Then at night, all the heat that the water absorbed has to bleed off before it can freeze, and so everything underneath the Wall-o-Water, the plant and the air surrounding it, stay warm and protected from the cold nighttime air.
I am expanding my garden beds- this year I am going to try tillage radish + crimson clover as cover crops in the new areas to break up my shitty clay soil.
If you don't already, get some compost piles going. Compost will really help improve the quality of your local soils, by improving both drainage and moisture retention, and the ability to hold onto nutrients that your plants need. Since you're in the Great Frozen North, it might be useful to get an insulated compost bin, like the
Hotbin or similar. An insulated bin can be kept going between 40-60C year-round, even in the sub-freezing dead of winter, so
long as it is kept fed.
If you do get an insulated bin, divert
all of your kitchen and yard waste to it. Yes, even the stuff you normally aren't supposed to send to compost because it will get stinky and attract pests, like meats, fats, and bones. The great thing about insulated bins is that because they can hold 40-60C, they can more quickly break down slowly-digesting waste like meats and fats. About the only thing I would hesitate to send to compost would be diseased plants, like say, tomatoes that got killed by fusarium wilt. For something like that, I would have to research what temperatures are guranteed to kill off the pathogens, and whether I had enough nitrogen-rich kitchen/yard waste on hand to keep the bin fed enough to maintain those temperatures long enough to ensure the pathogen fungus/bacteria/virus/etc had been killed off.
People in more agreeable climates- how’s your spring going, what have you got growing? Fellow arctic enjoyers, how are you hanging in there until winter releases its last icy grip?
Like
@waffle, above, I have started peas, turnips, carrots, and other early-spring plants that can handle a little cold. My warm season crops are still in the grow tent. I've only started my tomatoes and peppers right now, and some of the slower herbs like oregano and rosemary. I'll be waiting another week to start my cucumber-family (squash, cucumbers, mellons) plants. Their roots are
very fragile and sensitive, and they won't grow as well if you let them get too big and rootbound in the small pot you start the seeds in before transplanting them outdoors.
