Hydroponic Seedlings Station
Fresh and healthy seeds shall sprout for 2 to 15 days with the correct temperature 16°C to 24°C (60°F to 75°F), the humidity, and lights.
Leaves need lights for photosynthesis.
Transplant the seedlings 30 days after sowing the seeds.
keep 10 cm apart if they are transplanted in the soil.
It is natural that some of them will survive some will not.
It is natural that some of them will survive some will not.
Harvest 4 to 6 weeks after transplant.
Some sooner some later.
Trim the fresh leaves and allow them to continue growing.

Putting the seeds into the groove of the sponges.
you can also squeeze the seed in between the gaps.
When the seeds are fresh and healthy, all of them start sprouting on the 2nd day.
They will appear like this way in 2 weeks' time:
Wait for another 3 more weeks, check the water daily do not let them dry out,
let them further develop their root system before being moved to the hydroponic systems.
They will have a much higher survival rate with a stronger foundation.

Your can easily buy the fresh seeds from online stores, gardens, farms, or even supermarkets.
read the buyers' comments on the online stores should be able to know who's seeds are reliable.

Sprouting on the day 2.
Yes, we still can recycle and use the healthy sponges after one or two rounds of harvesting, if they are not rotten. Wash them well and a good sun bath before re-use again..

Press and soak the sponges in the water.
Press out all the air from the sponges.
Keep half-height of the sponges with water.
Drop one to three seeds in each cell.
Check water daily.
Wait for three weeks.

How Long Do Lettuce Seeds Take To Germinate?
" Lettuce seeds take 2 to 15 days to germinate. Lettuce seeds germinate faster with optimal soil temperature, humidity, and air circulation. "
"The University of California suggests that it will take lettuce seeds around 2 days to germinate at a soil temperature of 77 degrees Fahrenheit (25 degrees Celsius).
On the other hand, lettuce seeds will take around 15 days to germinate at a soil temperature of 41 degrees Fahrenheit (5 degrees Celsius).
It will also depend on various other factors that affect time to seed germination – let’s get into some of those now!"
Temperature to germinate Lettuce Seeds:
No of Days Seed Sprouts Temperature Temperature
(degrees Fahrenheit) (degrees Celcius)
Min 15 days 32°F 0 to 5 °C
Ideal 2 days 60 °F to 75 °F 16°C to 24 °C
Max 85 °F 29.4°C
Above this temperature,
they will not Germinate
" Lettuce seed will germinate at 35°F ( 2°C) but optimum germination is 70 to 75°F ( 21°C to 24°C) ). If the plants are sufficiently hardened, they will withstand freezing. "
"lettuce seed can germinate when the soil temperature is 35 to 80 degrees Fahrenheit ( 2°C to 26°C) ). The ideal soil temperature for germination though is 70°F to 75°F ( 21°C to 24°C). In cooler temperatures, germination takes longer. When temperatures are warmer than 70 to 75 F ( 21°C to 24°C), lettuce seed may not germinate."
"Lettuce is adaptable to many growing conditions but likes it cool - around 60°F to 65°F ( 15°C to 18°C). "
" Lettuce seeds need light to germinate, which is why they are planted in shallow soil. If you start lettuce seeds indoors, give the seedlings bright overhead lights such as LED during germination."
