Goldmine by Heavyweight Seeds

With Goldmine, the first thing worth noticing is the difference between indoor and outdoor expression. Under lights, the plant stays fairly compact at around 80 to 120 cm; outside, it can reach roughly 200 to 300 cm. That is not a minor detail, but the centre of the variety.

The base of Mazar x AK49 explains this split well. Mazar keeps the plant closer to a heavier, indica shaped body, while AK49 brings more drive into the build. Goldmine is therefore not a low compact line, but a strain that behaves quite differently depending on where it is grown.

Indoors, the growth direction should be chosen early. Topping, LST or a calm SCROG setup can help when the plant needs to be kept flatter and more even. Outdoors, stability matters more: with a larger body and heavier flower zones, Goldmine needs air inside the frame and enough support as it moves toward the finish.

Flowering takes around 9 to 10 weeks, with outdoor harvest usually around early October. The yield follows the same size logic: about 500 to 600 g/m² indoors, and under suitable outdoor conditions well above 1 kg per plant.

Berry, honey and earthy depth give Goldmine a warmer direction than the Diesel or citrus lines in the range. The variety carries enough identity through the contrast between compact indoor behaviour and a much larger outdoor body.
