These high impact trays can also be used by themselves for the small-scale grower or for the pro that just needs a little extra production area, as growing trays with built-in drainage.  They can be placed on any rack or table suitable for cultivation. This dual-level channeled  design, engineered for proper drainage, will make sure that your plants do not stay too wet  so that they do not invite any number of unwanted pathogens that can come around in  poorly drained or standing water areas. The commercial mobile rack tray can be used in  systems withoverhead irrigation or in growing systems with bottom watering like ebb and  flood configurations without fear of overwatering.  Made of BPA-free, ABS plastic, so you do not have to be concerned about growing consumable  plants on them and each tray has rounded edges for ease of cleaning. The Commercial Mobile  Rack Tray is designed by the folks at Wachsen Professional, who know all about commercial  growing systems for high volume producers, so you can be assured of its quality and performance.
