MR NICE G13 Haze Regular Seeds This is a hybrid that has had to be inbred since the G13 was only available as a female clone. In fact all the G13 hybrids offered at MNS are IBL as that was the only way to retain the strain in a form to produce seed for distribution. Strength and effect are two od the principal attributes found in this strain and it can be combined well to make new poly hybrids.
