what temperature to germinate cannabis seeds

We recommend 27 – 33 degrees as the optimal germ temperature!

All hemp seeds have different germination times depending on the breeder. The longest take up to 14 days to germinate. Therefore, do not throw the seeds in the garbage after 2 – 3 days just because you don’t see any germs yet. But keep in mind that there are always seeds that just don’t want to germinate. It is a natural product.

Cannabis seeds, like most other seeds, germinate with normal plant soil. Sufficiently moist and warm, they only start to germinate and grow over time to a beautiful plant. A hard shell protects the soft core of the seed, which consists to a large extent of moisture and nutrients. Thus, the seed survives a prolonged cold spell without it being damaged. Here you will find out how you can germinate the valuable cannabis seeds:

��� What we do not recommend to you is germinating the cannabis seeds in the soil. The germination rate is here up to 40% lower than with the method shown by us.

We have observed that the seedlings grow slowly or not at all if there is too much water. Under no circumstances let the kitchen paper dry out completely. The germs could stick and tear off.

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.

Before you can be met with bountiful hauls of dank buds, there are several stages of cannabis growing that take precedence. Unless you can successfully germinate cannabis seeds, you won’t have a plant to harvest. Give your seeds the best possible start in life by reading our definitive guide to germination.

WHAT TO LOOK OUT FOR IN CANNABIS SEEDS

• 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

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.

To avoid disappointment, seeds that have a darker colouration stand a better chance of germinating, while pale green or white seeds are likely to fail. Even if dark seeds look slightly damaged, they should be planted anyway. There is a good chance they will still germinate, even if the outer shell is somewhat crushed.
