One dome lid - This lid ensures maximum light incidence and provides useful surface area for the collection of condensed water. The unique lid opening allows seeds to be watered from above. It also ensures optimum flow of oxygen and release of metabolic gases. Three seed trays - Large, transparent seed trays enable you to cultivate up to three different types of seeds as the same time. Or, if you prefer, you may harvest continually by staggering the sowing of seeds. The trays are specially developed to ensure that sufficient moisture is always present. Unique ventilation slits - 3 ventilation slits in each seed tray and in the lid ensure that metabolic gases and heat are completely released. One water tray (base) - After seeds have been watered, all surplus water is collected in the water tray at the base of the sprouter. The tray is the same colour as the earth, thus ensuring that the water in the Greenhouse is neither exposed to light or heat.
