• The ideal temperature is between 22° and 25°C (71–77°F)
• Your growing environment should be damp/moist, but never wet
• Relative humidity range should be between 70% and 90%
• Seeds favour fluorescent lighting (Cool White code 33)
• Minimise the amount of seed handling you do
• In hydroponic/rockwool plugs, the ideal PH value is 5.8–6.2

Regardless of where you get your seeds from, it is best to give them a slight (and delicate) inspection before planting. Most of the time, all seeds will germinate; however, poor-quality seeds will produce a weaker plant. Unfortunately, that is something you will not find out until well into the vegetative and flowering stages.

GERMINATION TEMPERATURE PLAYS A CRUCIAL ROLE

Two or three weeks after germination, your young seedlings should be ready for their new home. At this point you have two options; transplanting them into soil pots, or taking on the challenge of hydroponics. You’ll know when the seedlings are ready to be moved because the root system should start to poke out of the bottom of the wool blocks. As long as the roots haven’t begun to engulf the bottom half of the wool block, they will seek out water and nutrients in their new surroundings and continue to grow downwards.

There is, of course, a far simpler way to germinate seeds. Ideal for beginners, the feminized starter kit by Royal Queen Seeds has everything you need to kick-start your next cannabis project.

If you don’t like the idea of pre-soaking your soil, you can use a spray to moisten the holes before you plant each seed. With enough moisture surrounding your seeds, you can still encourage a root to develop.

In some strains, cold weather may also trigger hermaphroditism, meaning that the plant grows both pollen sacs and buds, leading to self-pollination and dramatically decreased yields in turn.

Autoflowering strains are another great option for growers living or growing in cold regions. Cannabis Ruderalis, the variety of cannabis bred with indicas and sativas that gives descendants their autoflowering properties, is native to Central/Eastern Europe and Russia, and is renowned for being especially hardy. Plus, the fact that autos can go from seed to bud in as little as 8 weeks makes them optimal for sneaking in an extra early Spring or late Autumn harvest.

How Cold Can Cannabis Get?

Bud rot is a real threat for growers cropping in cold weather with next generation lighting like LEDs and CFLs. Hydroponics and LEDs can be a recipe for disaster in cold weather, as both root rot and bud mold can be real threats if feed water is below room temp and RH exceeds 60% during flowering.

Maintaining environmental control year round is the only long-term solution; keep an eye on those thermometers and make adjustments when necessary. It’s a whole lot easier to heat a grow room in winter, than it is to cool a sweltering HID grow show in high summer.

Greenhouses essentially give you the freedom to grow weed all year round, given you have adequate control over the lighting, temperature, and humidity inside your greenhouse. If you’re considering using a greenhouse to grow your own weed, here are a few things to consider:
