Haxnicks Bell Boys 4" (3 Pack) Code: 210019 4" Bell Boys are designed to fit neatly onto the tops of ordinary 4” plastic flowerpots, transforming them into an intensive growing system for seedlings, plugs and cuttings. The adjustable vent on top helps create a controllable micro-climate for the perfect growing environment, without the need for a heated greenhouse or standard propagator. Using Bell Boys with pots is a very space-efficient alternative to the usual seed or cell trays. They fit easily onto a windowsill so you can raise seedlings, plugs and cuttings very successfully inside your house. Virtually all leafy and woody cuttings and some seedlings need the added depth of a pot as opposed to a shallow seed tray. Bell Boys provide the propagator lid that significantly increases the rate of successful seed germination and promotes strong, even growth of plugs and cuttings.
