The Mac (aka Mac1, aka Miracle Alien Cookies)Green Crack

Longer-flowering, sativa-dominant hybrid with very big yields and extreme THC content.

Mack & Crack Feminised is a sativa-dominant hybrid strain bred by crossing The Mac (aka Mac1, aka Miracle Alien Cookies) with Green Crack. Growers can expect to harvest some very high yields of very resinous, colourful buds with extreme potency levels. Easy to grow, even for beginners.

Mack & Crack takes 10 - 11 weeks to complete its flowering phase when grown indoors. Yields are very good indeed, and growers employing hydroponic techniques will reap the largest yields in a slightly faster finishing time. These plants develop multiple side-branches and SCRoG allows growers to exploit this attribute to the max. Buds are large, dense and jam-packed with resin. With cooler temperatures near to the end of flowering some attractive autumnal shades will develop. Due to the size and density of the buds it is advised to lower humidity in the few final weeks, thus reducing the possibility of mould causing issues.

The terps. produce aromas of citrus, diesel with some herbal/floral notes. THC production can reach an amazing 30% makiing this a highly potent strain that is not recommended for the novice consumer. The effects are uplifting, euphoric and energetic.
