How to read these figures.Cannabinoid, yield and flowering values are ranges compiled from our own grow-outs and the source breeder's records for this lineage — not a lab certificate for the pack you receive, and not a result your room is guaranteed to hit. Phenotype, light, medium and feed all move them. The germination figure we do test per batch, and that method is published on the germination guarantee page.

Reported effects

Super Lemon Haze is the textbook "creative Sativa": fast-acting cerebral lift, sharp focus, sustained energy, and pleasant social euphoria lasting 2-3 hours. The high THC ceiling can push into racy territory if dosed heavily — beginners should start with a single hit.

These are consumption effects reported by growers and consumers for this cultivar. Nothing here is medical advice or a claim that this plant treats, prevents or relieves any condition.

Growing Super Lemon Haze

Super Lemon Haze stretches significantly (2-2.5x) in early flower — SCROG, mainlining, or topping is required indoors. The 9-10 week flowering window is on the longer side; plan light cycle accordingly. EC: 1.6-2.0 mid-flower. Indoor yields 500-600 g/m² with proper canopy management. Outdoors in Mediterranean climates, plants finish in mid-to-late October producing 600-900 g per plant. Mold resistance is good. Trichome production is heavy with the characteristic frosty white-yellow coloration.
