G1 Grain masters are created directly from the mother plate ensuring that the culture is as genetically similar to the original culture with its vigor, performance, and expected results. G1 Grain Masters can be used to inoculate end substrates for fruiting or expanded into G2 Grain or other mycelial carriers depending on grower needs. G1 Grain Masters should be used in clean areas and with knowledge of contamination risks and variables that impact culture performance. This is the only form of grain spawn that we warrant and request any problems with the next or subsequent transfer in your lab to be photo documented and you have contacted us within two weeks of that transfer. G1 Grain Masters are produced on four pounds of hydrated and sterilized rye grain in type 14A gusseted bags with 0.5micron filter patch. G1 Grain Masters are made to order (please allow 2-6 weeks for delivery).
Note of purchase: Before the final placement of your order, you will be asked to read and agree to our Culture Purchase Terms and Conditions as a final step prior to shipment. This will help ensure success of clean and vigorous propagation in your own lab.
