Watermelon ZkittlezVelvet Moon
Productive and potent hybrid with slight indica-dominance. High resin production.
AlienZ is the result of crossing Watermelon Zkittlez, from Dying Breed, with Greenhouse Seeds' own Velvet Moon strain. This 60% indica hybrid produces high yields with plenty of resin and a complex palate.
AlienZ plants grow with a typical Christmas tree shape and can develop into seeds_plant_height=seeds_plant_height=Tall plants outdoors where they can reach anywhere between 150 - 250 cm. Indoors, flowering will last for 8 - 9 weeks and production is high in this environment. Outdoors, plants will be ready to harvest by the end of September in the northern hemisphere with each plant capable of yielding up to 1400 gr. Growers can expect to see some nice colours towards the end of flowering especially when cultivated outdoors.
The effects are potent and long-lasting.

I didn't purchase Alien Z I purchased velvet moon x watermelon zkittle. I purchased 3 seeds and upon review only 2 seeds were mature and viable. You could easily see one seed was no good! Please replace one seed!
