All about Geist OG Fast
The variety Geist OG Fast is the result of a thorough cross between Geist OG and OG Auto by Humboldt Seed Organization. After two years of intense dedication, this strain has been stabilized to reach a faster flowering and to offer a unique gas-like flavor that distinguishes it among other varieties. Besides, it also stands out for being an excellent choice to perform extractions due to its impressive resin production.

The effects of Geist OG Fast are highly relaxing, becoming an ideal choice to put an end to a stressful day or to enjoy a relaxed friend’s gathering where interesting conversations flow naturally. The THC levels of this strain are impressively able to reach up to 26%, which means that it is not recommended for beginners or users with low tolerance.
Geist OG Fast flavors and aromas
The flavors and aromas of the Geist OG Fast are absolutely exceptional. This variety offers an unparalleled gas-like flavor profile, with subtle citrus notes that provide some freshness to the experience. One can also note some earthy nuances that add deepness to the taste, as well as metallic reminiscences that provide an intriguing singularity.

How to grow Geist OG Fast indoors
Growing Geist OG Fast indoors requires some specific care. It is recommended to perform regular prunings and control the size of the plants to avoid problems with growing lights. This strain is able to grow up to 180 cm (6 ft), that’s why a relatively short growing period is recommended to keep their size under control.

Under optimal conditions, it is possible to get yields of more than 1000 grams per plant, becoming an exceptional choice for outdoor growlers looking for abundant performances.

This strain is a showstopper! Harvest in record time, and the bud quality is impressive. They end up rock-hard, super resinous. The taste is very good, and even though I used a pretty potent PK, it didn't affect it at all. I recommend defoliating the lower parts to optimize the light. One of the best I've ever grown, without a doubt.
Translated from Portuguese
Essa strain é um espetáculo! Colheita em tempo recorde, e a qualidade dos buds é impressionante. Eles ficam duros como pedras, super resinosos. O sabor é muito bom, embora eu tenha usado um PK potentinho, não afetou em nada. Recomendo fazer uma desfoliação nas partes baixas para otimizar a luz. Uma das melhores que já cultivei, sem dúvida.
