Frequently Asked Questions

The towers are vertical: water and nutrients are fed from a sprinkler head at the top and trickle down past every site, so roots take up nutrients as the water passes and get oxygen when the cycle stops.

The Pro Shelf flows nutrients through trays, so roots stay in contact with water except during the oxygen cycle. It is gentler on plants and generally produces a faster harvest, and it adds an 85-site germination bed and a lighting control panel.

Towers need about 24″ of floor diameter and 3′4″–5′6″ of height. The Pro Shelf needs a 3′ × 18″ footprint and about 5′6″ of height. Both are designed for indoor rooms, classrooms, and greenhouses.

Capacities across the range run from 48 to 96 planting sites. The Pro Tower Garden is offered in 48, 64, 80 and 96-site builds; the Pro Shelf has 72 planting sites plus an 85-site seeding bed; the NutraTower has 72 sites plus a 76-cell seedling tray; the Pro AeroTower has 48 sites.

Towers are offered as 6, 8 and 10-layer builds, and that limit is set by the water pump. Extra layers beyond those would need a larger pump and a higher-capacity reservoir, so we do not sell add-on layers separately — pick the capacity you want up front.

The 72-site Pro Shelf and the 80-pot tower with LED grow lights are each usually enough for a family of four to five, provided you keep planting cycles running rather than waiting for a full harvest before replanting. Lettuce and most herbs take about three to four weeks.

The nutrient chamber holds about 7 gallons, which typically lasts around two weeks before it needs topping up. The system does not need to be connected to a water supply.

Root vegetables. Carrots, onions and potatoes will not work in the towers. The shelf system does have limited room for a small selection of bulb-shaped crops such as turnips and baby potatoes.

If your system sits outdoors or beside a window that gets about eight hours of daylight, you do not need supplemental lighting at all. Indoors, the LED builds carry their own grow lights, and the Pro Shelf adds a control panel for lighting levels and timing.

Lettuce and most herbs take roughly three to four weeks. Keeping staggered planting cycles running — rather than replanting only after a full harvest — is what keeps a system producing continuously.

All products are covered by a 1-year warranty against product defects from the date of sale. During that period Nutraponics will repair or replace the product if such defects are present.

Yes. School purchasing is supported end to end — quotes and estimates, purchase orders, Net 30 terms, tax-exempt documentation and W-9 forms.

Yes. Tell us about your school and we will come back with custom pricing and an implementation plan. Request school pricing and consultation.

The Classroom Bundle pairs either the Pro Shelf — best for whole-class visibility and demonstrations — or the Pro Tower 80 LED, which suits labs and rooms with limited floor space. Multi-classroom bundles are available too.

Yes. Bundles include NGSS-aligned lessons written for Nutraponics systems, a teacher implementation guide, a student workbook, a crop handbook, posters and printables, plus startup supplies and onboarding support.
