It is astonishing, how well the combination of Lechuza Pon mineral substrate and the Narcos Seed genetic works. Strawberry Merengue shows explosive growth. However, one leaves got brown edges, so I watered a little more. Anyway, I am still not sure when the watering from the reservoir at the bottom of the pot starts working; until now, the lady does not seem to draw from there, but is not using too much water anyway. The manual says you should wait 12 weeks for the roots reaching the reservoir, but I doubt the this vigorous girl takes so long.
