Can seeds germinate in a dark cupboard?
We learned that the answer was a qualified yes. It appears that seeds begin to sprout regardless of whether they are exposed to light or not. But seeds need light in order to form leaves.
Do tomato seeds need light while germinating?
Tomato seeds should be started indoors 6-8 weeks before your last frost date in spring, which is the average date of last frosts in your area. Seeds don’t need light to germinate, although after germination, you should ideally give the seedlings 14 or more hours of light a day.
Do tomatoes germinate in light or dark?
Germination Conditions Tomato seeds do not need light to germinate, but they do need proper warmth and moisture. Temperatures around 70 degrees are ideal. Temperatures between 50 and 75 also work.
Is it better to germinate seeds in the dark or light?
Most seeds germinate best when they’re placed in the dark. The presence of light, which is crucial to seedling development, may actually stunt the process of germination.
Which seeds require darkness to germinate?
Some other popular types which prefer darkness for germination are:
- Calendula.
- Centaurea.
- Delphinium.
- Gazania.
- Nemesia.
- Primula sinensis.
- Schizanthus.
At what temperature do tomato seeds germinate?
65° to 85°F
For example, the optimum temperature range for tomatoes is 65° to 85°F (see previous chart). Within that range, it takes approximately 6 to 8 days before seeds germinate. Tomato seeds may still germinate at 50°F, but it will take over 40 days, and there will probably be no germination if the soil temperature is 104°F.
How quickly do tomato seeds germinate?
7 to 14 days
At a temperature of 21 degrees celsius, tomato seeds usually germinate in 7 to 14 days. After germination remove the smaller plant. Pot on the tomato seedlings as soon as they’re big enough to handle. Hold the plants by the leaves, taking care not to touch the stems, and transplant them into 7.5cm (3in) pots.
How many days it takes for tomato seeds to germinate?
The ideal temperature required for germination of tomatoes seeds ranges between 21 to 27℃ (70 to 80℉). For best germination results, keep the pots in a warm and dark place. The seedlings should appear in 10 to 14 days.
Do tomato seeds need to be dried before planting?
Tomato seeds retain highest germination rates when dried to between 6 – 9% moisture content. Fermentation of the seeds for about 48 hours, along with the tomato pulp produces higher germination rates. However, fresh tomato seeds can be dried on paper towels for 2-3 days before planting.
What seeds require darkness to germinate?
Do tomato seeds germinate better in the dark?
Do tomato seeds germinate better in the dark? Since seeds don’t need light to germinate, you can germinate them anywhere, even inside a dark cabinet if you like. Drop in one seed per hole and cover with enough soil so it’s level. Add enough water to moisten the seed and added soil, and replace the tray’s plastic cover to prevent moisture loss.

How long does it take for tomato seeds to germinate?
If temperature is kept consistently and sufficiently warm, your tomato seeds will usually germinate within 5 to 10 days. Best to keep temperature range 70 to 80F (21 to 27C). The lower the temperature the slower the germination. However, temperatures below 50F (10C) or above 95F (35C) are poor for germination.
Can You germinate tomato seeds on a paper towel?
To germinate tomato seeds on a paper towel, wet the paper towel until it is damp (not soaking wet). Then, lay out the tomato seeds so that they are separated (not touching). Be sure to keep the paper towel and seeds in a warm place, to encourage faster germination and higher germination rates.
