OG Ghost Train haze
Sativa dominant productive Auto
Fantasmo Express a.k.a Auto OG Ghost Train Haze, is a project now complete that Mephisto Genetics company and customers have been waiting for.
It is the most sativa dominant Mephisto strain available for purchase.
They grew and evaluated a number of variants in the OG Ghost Train Haze series of strains from Rare Dankness, and from #1 seeds they found a stellar male to work with, pollinating a lovely hybrid indica/sativa auto that they'd previously bred to be very easy to grow, nice plant size and resin profile.
Fantasmo Express is an easy and interesting plant to grow, she starts small looking indica and OG dominant in appearance, there's then two onsets of growth. During the pre-flowering period she gains a lot of size, then as flowering sets in, every shoot and bud site grows extremely quickly and efficiently.
Yield is excellent, 90g plus is easily achievable with a kind hand and environment.

It's been a while, but I remember how much I enjoyed Ghost Train. Grown in organic soil and used Nectar for the Gods

Fantasmo Express Auto Feminised Seeds
Two of these worked well outdoors. Grown very simply direct from seed in 12l containers with a quality potting mix, a little BioBizz grow and bloom given here and there but was not a high demand feeder. Plants themselves were similar in growth but showed a bit of difference in flowering, one more to the Haze and the other OG; the two sides of the Ghost Train Haze parent I believe. Flowers were extremely resinous once finished, hazy, earthy notes in the taste. A very good quality hybrid uppish high from these autos, the yield potential perhaps a bit low with these but headstash that everyone will want to sample ;)

Grew alongside auto mazars - 2 very different plants. First grow so probably made mistakes - only germinated 2 out of 5 unlike 5/5 mazars. Both were LST but remained small plants. They were not dense buds at all unlike the mazars and yield was much lower - approx 30g off one & a bit more on the other. However, I bought these after the mazars as I often prefer a high than a stone and the smoke is exactly what I wanted - a great smoke.
So, very happy overall under toughish conditions this summer with high humidity - would grow again and look at othe Mephisto strains.
Seedsman you were great to purchase from x

Very impressed with the speed of growth and size of buds! The aroma and flavor were fantastic. 4 of 4 seeds sprouted and grew to maturity within 80 days. Never have I felt such wonderful sticky buds.

Easy to grow and have me a great yield, considering its small stature. Flowers were more indica like: thick and dense. This is a good morning and daytime bud since the high is very mild. My plant was grown hydroponically with Botanicare nutes, and under a LED panel, one that has UV and IR diodes.

Fantasmo Express is the favorite among all of my friends and my introduction to Mephisto Genetics. A great breeder, a great plant - vigorous growth, easy to train, fat yielder, and a smooth, yummy smoke with a lot of sativa zing. A GREAT introduction to autoflowers.
