One channel of greens
A leafy crop from seedling to canteen in a single channel, with the solution logged twice a week and topped up to a rule the class writes.
Skills · Hydroponics
Grow it without soil.
A channel, net pots, roots in water, and a reading taken often enough to act on. For schools with a corridor and no field. Classes 6 to 12.

Why hydroponics
The plant tells you nothing. The reading does.
In soil, a plant sits in a buffer that forgives a week of inattention. In water there is no buffer: the strength of the solution and how sour it is decide everything, and both drift. That is a hard lesson in an unusually honest form, because a class that stops measuring watches the result within days.
It is also the version of growing that fits a school with a corridor and no ground, which is most of the urban schools we talk to.
The work
What students actually build
Example briefs, not student work.
The drift log
Strength and sourness read every other day for a fortnight, charted, and the pattern explained. When did it move, and what had the class done that day?
Water against soil
The same crop, half in the channel and half in a tray of soil. Growth measured weekly, and water used measured too. The answer is rarely the expected one.
Classes 6 to 12
Class by class.
Fit before ambition.
Classes 6 to 8
a channel, a reading twice a week, one crop to harvest. Kaushal Bodh projects under work with life forms (Circular Skill-81/2025, 28.10.2025), assessed on viva, activity book, portfolio and teacher observation.
Classes 9 to 10
controlled comparisons, nutrient mixing done by the class, water use costed against a soil bed.
Classes 11 to 12
a system designed and built to a brief, and the chemistry and economics behind it argued in the portfolio.
Classes 6 to 12
This is the most equipment-dependent of the growing skills and the least demanding to teach, because the system enforces the routine: miss the readings and the class can see what happened.
We train the mixing and the meter first, since those are the two places a teacher feels exposed, and the crop calendar is planned against the school year so a harvest does not land in the middle of exams.
Equipment
Equipment is bought. Capability is built.
A channel or a set of buckets, net pots, a small pump, nutrients and a meter. It is the one growing skill with a real shopping list, so we scope it against what the school will actually keep running. CBSE's CSL equipment list is explicitly "suggestive", adoptable per readiness (Circular Skill-13/2026, 20.03.2026).

Questions
Honest answers.
Does it need power all day?
A small pump on a timer, and in the simplest builds none at all. We size it so a power cut is an inconvenience rather than a lost crop.
What happens in the holidays?
It is planned for in April. Crops and start dates are chosen against the school calendar, and the simplest systems tolerate a fortnight unattended.
Isn't this expensive?
It is our most equipment-dependent growing skill and we say so before you commit. We will tell you if a tray of soil would teach the same thing at your school.
Book a workshop
Half a day at your school. Here is what happens.
How a school and Hankernest find out whether Hydroponics fits before anyone commits to a year. Inside your timetable, with your teachers and your students, on what you already own.

Your class builds
One channel set up and seeded, with the first reading of the solution taken and written on the log by the class.
And learns. What the two readings mean, and what the class will do the day one of them moves.
