How to grow White Critical Express
Seb's take
Kalashnikov Seeds bred this from White Widow, Critical Mass and an undisclosed 'secret hybrid' — the Soviet naming is the only thing here that isn't understated. Fast-finishing and field-tested from Ukraine to Spain, she rewards a SCROG frame with heavy, well-balanced buds. The high sits evenly between Sativa lift and Indica calm, tested at 21% THC.
Growing White Critical Express: what to expect
Feminized photoperiod stock. You control when she flowers, which is a responsibility as much as a convenience; the light schedule guide keeps you on the right side of it.
Flowering is done in roughly 7 weeks. The calendar will suit the impatient; the flowering notes will suit everyone.
Expect roughly 120 cm of plant. Manageable, though she'll appreciate a little training if your headroom is tight.
Expect 450 – 600 g/m² — a working grower's yield, reliable rather than theatrical. The harvest guide will see it in safely.
Listed at 21% THC — potent, verifiably. The figure comes from the breeder's testing, not from our enthusiasm.
