    Abstract: An improved growing tray apparatus including means for moveable positioning the tray with respect to a support surface such that the tray and/or the surface may be transferred while the tray is in use. The apparatus incorporates a side wall configuration which permits the tray to be secured on a pallet or similar support structure and moved therewith, but does not interfere with plant care and nurture. Off-season storage is also facilitated by the side wall configuration. Choice of construction material enhances the benefits available through use of this apparatus.
