Well it’s not stable, out of ten seeds. Only three came up. The two of them was identical with white dwarf and just stopped growing after week two during to high temperatures (32 degrees). The last one, a very hashish smelling lady clearly an Morocco phenotype, she loves the heat!! So one keeper out of ten seeds. But sadly it doesn’t auto flower.
At week 6 from seed, I had to treat her like an photosensitive and switch to 12/12.
First and only time I’m buying autos at greenhouse seeds. this comment

Good beginner choice, I use these in the summer as a bumper crop when temps are too high to grow indoors. Smell ultra sweet with a pretty decent smoke for the short time investment and seeds are priced low. this comment

Not too bad, it fits the breeder's description. Don't waste time, money and effort to grow it professionally indoor. You don't get much in return. It's well suited for low level balcony or window grows. Stays lower then 0.5m and it really doesnt take longer then 8 weeks from sprouting. The earth should be well aeriated and the temps not under 23°C. No fertilizers, special techniques or whatever needed. You could call it idiot-proof :) this comment

GREEN-O-MATIC by Greenhouse Seeds Review by Blain

A lovely strain for beginners. She is reasonably tolerant to environmental stresses such as low humidity and higher heat, as well as over-feeding. She has a very low odor profile, especially when grown organically, which compliments her small stature and makes for an ideal stealth operation. A distinctively sweet and yet very subtle indica scent begins from around day 30 from seed, on through flowering which ends around day 54-57 from seed. There is a nice and relaxing and yet very functional stone.

*Beginner friendly

*Tolerant to stress

*Low odor and height profile


*Average to below average yield this comment

gute keimrate und blühen sehr schnell. autoflowering funktion hat auch super funktioniert, allerdings auch schon nach 2-2 1/2 wochen, weshalb die kleinen gerademal 10-15 cm groß wurden und entsprechend wenig auf die waage brachten. durch den geringen preis und den starken indica/ruderialis eigenschaften dennoch gut brauchbar und das an bubblegum haze erinnernde aroma ist es allemal wert green-o-matic anzubauen ;) this comment
