Airborne G13 S1 by Brothers Grimm Seeds
Airborne G13 S1 by Brothers Grimm Seeds is a feminized S1 line based on a selected Airborne G13 clone. Within the catalog, it represents a compact, indica-leaning cultivar with a focus on uniform growth and controlled plant structure.
As an S1 release, this line is created through selfing a stable mother plant. The goal of this method is to transfer the core characteristics of the original clone into seed form as directly as possible. At the same time, some variation can still occur, as individual traits may express differently across plants.
In growth, Airborne G13 S1 tends to stay relatively compact, with tight internodal spacing and solid lateral branching. This makes it well suited for controlled indoor setups as well as uniform canopy systems such as SOG. Outdoors, it remains manageable but can develop more mass when given enough light and space.
Flowering time is listed at around 55 to 60 days. Indoors, yields of up to 500 g/m² are possible under stable conditions. As usual, final performance depends heavily on light intensity, substrate, container size, and overall crop management.
The profile is generally described in a classic hash-forward direction, supported by earthy and slightly spicy notes. Overall, the line stays clearly within a traditional indica-oriented aromatic range.
As a feminized S1 release, Airborne G13 S1 is primarily suited for growers looking to work with a compact, manageable line that maintains a close connection to an established clone.
