High Voltage Fast

Descrizione

High Voltage Fast by High Speed Buds

High Voltage Fast looks almost restrained indoors. Under lights, the plant stays low at around 80 to 90 cm, while outdoors it can reach roughly 180 to 220 cm. That contrast separates it clearly from the Auto version.

The line comes from Grape Stomper x High Voltage Auto and remains photoperiodic as a feminised Fast version. This gives more room for structure work before flowering. Topping, LST or a flat SCROG can make sense when the growth should be spread wider before the short bloom window starts.

With 45 to 55 days of flowering, High Voltage Fast moves quickly without following the usual autoflower logic. Once bloom is underway, the frame should not be changed much. An open canopy, stable branches and air between the flower sites matter more here than late reshaping.

Outdoors, the harvest window falls around 20 August to 10 September. For a plant that can build much more height outside, that is early. Under lights, production sits at about 550 to 600 g/m², carried by a 50/50 structure that is neither purely squat nor strongly stretched.

Grape Stomper shapes the fruity, grape-led direction, while the High Voltage Auto side brings the shorter ripening window and the more compact indoor frame. Under lights, the plant stays low and easy to guide; outdoors, it shows far more body without losing its early harvest window.
