MM Genetics' Master Hemp Description

Master Hemp CBD was created following a rigorous selection process over a period of three years of multiple crosses and field trials. Master Hemp is an 70% sativa and 30% indica plant.

The wait is over – Master Hemp high CBD strain is finally here with CBD:THC ratios of 32:1!

Three different lines were utilised in its creation including MMG’s high-CBD CD-1 strain, known for its excellent CBD concentrations as well as its strong and sturdy structure. Another component was an old Swiss line which brought greater compactness to both plant and bud.

This new strain brings some exotic terpenes to the table and some not normally associated with cannabis. In this way the “entourage effect” is delivered to consumers adding terpenes to the wide range of cannabinoids which include CBC, and THCV alongside the expected CBD and THC, although very low amounts of the latter.

In order to maximise the true potential of this plant it is recommended to grow either outdoors or in a greenhouse environment where it can reach a height of 300 cm. yielding 450 gr/plant with harvest time being either at the end of August or the first week of September at the very latest in northern latitudes.

Approximately 30% of plants will turn purple towards the end of florescence. Indoors can also see growers produce successful crops with the following recommendations; first, it is grown in a 12/12 light/dark scenario throughout its cycle not just during the flowering phase.

Secondly, it only requires a light feeding schedule and excessive nutrients will cause lock-out of the same to the plant’s detriment. Indoors yields of 400 gr/m 2 can be obtained in a 55 – 60 day flowering time.

Terpene production is excellent and is responsible for the intense scents and flavours of incense, lemon and bitter-sweet notes. CBD levels are very high at 12 – 16% while THC production remains extremely low at just 0.3 – 0.5%!

This strain will appeal to the therapeutic user or simply to those who wish to enjoy a richly-flavoured smoke or vape without the usual psychoactive response.
