MAC 11994 Jack herer
Longer-flowering plant that thrives indoors. Very high cannabinoid production and monster yields.
Mac 'n' Jack R1 is a sativa-dominant hybrid cross of MAC 1 x 1994 Jack Herer. Highly-vigorous strain that can easily get out of control so not suitable for the novice grower. Needs the full season if grown outdoors. Very big yields and very high cannabinoid production.
Due to its stretch and potential size, Mac 'n' Jack benefits from being put into flowering early when grown indoors taking upwards of ten weeks or more to complete florescence. Experienced growers can expect monster yields.
The terps. produce scents of lemon, incense, pine with earthy and sandalwood notes. Total active cannabinoids are between 25 - 30% giving a highly potent, uplifting effect.

Mac 'n' Jack R1 Feminised Seeds
It says to put in flower early because of size. We put in flower 3 weeks after pre flower is one week to early.
