Mephisto Genetics – Double Grape

SKU: mephisto_genetics_double_grape Categories: , Tags: , ,


In September of 2016 we released ‘Double Grape’ as part of our second illuminautos drop. Here’s what we said about it then: ‘Another clash of the Artisanal titans in the form of the two strains of grape heritage. From the offset of our F3 artisanal run last winter we had this cross pegged and written on our project board as a MUST DO! Insanely frosty and busting with flavour, ideal strain for extraction!’

Double Grape was the fastest illuminauto strain to sell out in Mephisto history, and a community grow-off soon ensued, so we knew immediately it was a strain we should pick to advance and bring back to the people for those who missed out on a taste of her. We have progressed the Double Grape another two generations, continually selecting the finest examples to work from and now can finally offer her as a F3 limited edition.

Strain behaviour:

Double Grape is an all-round pleasure to grow. She’s easy to grow and manicure and all too easy to consume! One of our frostiest, oiliest varieties we’ve ever produced and it’s not all show, the Double Grape packs a mean punch too. Both parents bring insane amount of trichomes to the table, and their distinctive individual grape based tastes combine amazingly to make something truly unique.

Double Grape has very nice vigour and grows with a relatively open structure, she will bush naturally, and with just a touch of leaf tucking even better. She will also adapt very nicely to LST and other forms of training when performed correctly. The cycle time is medium at 65-70 days to bring her to fruition in ideal conditions and is definitely one of the most pleasurable strains to grow from any of our collections. She has also tested as one of the most potent at a resounding 27% THC.
