A grow-your-own STEM lab for schools & preschools
Children seed, grow, harvest and eat their own greens in 4–5 weeks, right in the classroom.
Seed to plate within a term.
The full cycle fits inside a school term, so one class sees the whole story, from a tiny seed to a salad they grew.
- Plant about 2 seeds in each sponge cup
- Check water and nutrient levels each week (about 10 minutes)
- Compare crops: pak choy in 4 weeks, lettuce in 5, herbs in 7
- Weigh, harvest and taste what they grew
- Clean, reset and start the next cycle

Plant science
Seeds, roots, light and nutrients, seen through the clear logic of soil-free hydroponics.
Food & health
Where vegetables come from, and how fresh greens taste when picked the same day.
Sustainability
Growing food indoors, in a small space, and harvesting only what is needed.
Measuring & maths
Count cups, time the cycles, weigh the harvest and compare crops.
Two languages
Our crop list carries English and Chinese names, from 生菜 to 香港菜心.
Teamwork
Weekly duty rosters for checking water, and a shared harvest day.
