Genetics & Origin of Auto Royal Runtz
For Auto Royal Runtz, Royal Queen Seeds crossed the photoperiod Royal Runtz with a Ruderalis. According to the breeder, the original quickly became popular because of its THC content of 27% and its sweet flavour; the autoflowering variant was meant to allow a faster harvest and more inconspicuous growth. The genetics are made up of 50% Sativa, 45% Indica and 5% Ruderalis. At 19% THC, the autoflower stays below the value of the original strain, and the manufacturer gives the CBD content as low. Royal Queen Seeds calls it an all-rounder that combines yield, effect and flavour. The seeds are feminised and need no switch of the light cycle to go into flower. You will also find the photoperiod Royal Runtz in our range.

Growing Auto Royal Runtz: Indoor & Outdoor
Indoor Growing
In the grow box, according to Royal Queen Seeds, Auto Royal Runtz needs 10 to 11 weeks from sowing to harvest; the flowering phase itself lasts 7 to 8 weeks. There are two figures for the height: in the data sheet the breeder states 60 to 120 cm, elsewhere 70 to 100 cm. The yield is 350 to 450 g/m². According to the manufacturer, with a little training the strain can be kept inconspicuous even in cabinets – with autoflowers, gentle methods such as tying down the shoots lend themselves to this. You do not have to switch the light cycle. There is more on training and climate in the Growpedia.
Outdoor Growing
Outdoors, according to the data sheet, Auto Royal Runtz grows 70 to 120 cm tall and produces 70 to 100 g per plant. Here too, the figure of 10 to 11 weeks after germination applies. Royal Queen Seeds names long summers as the climate zone; a spot in full sun and sowing in the warm season therefore make sense.

At 19% THC it is weaker than the photoperiod Royal Runtz, for which the breeder states 27%, but in its words quite strong for an autoflower. The CBD content is low.
