About Sour Larry Cross

Sour Larry Cross blends the pungent diesel of Sour Diesel with the dense structure of Larry OG to deliver an uplifted, focused high and a zesty flavour profile. Bred for vigour and resin production, it favours a managed canopy, timely mould prevention and benefits from organic soil practices in temperate British climates.

Grow Difficulty:

Growing Sour Larry Cross is intermediate in difficulty and benefits from steady humidity control in a wet Welsh valley climate. Vigilant mould prevention and good air circulation make the difference between success and loss.

Flowering Time:

Flowering finishes in about 8 to 10 weeks under proper light cycles. Expect the plant to fatten buds in the final three weeks when nutrients are dialled in.

Yield:

Yield is medium to high with attentive feeding and bloom-phase care. Outdoors in Dorset it can produce solid crops when given space and sunlight.

Height:

Plants develop a medium-tall structure with long colas and side branching. Training like topping or low-stress techniques helps manage height for indoor grows.

Environment:

Indoors Sour Larry Cross responds well to SCROG and careful height control for its sativa stretch in Dorset. Outdoors it benefits from a sheltered southern aspect and late-summer sunshine when grown in Dorset gardens.

Climate:

Growing Sour Larry Cross in Dorset with a wet Welsh valley climate demands proactive mould defence and canopy management. Rain and humid evenings make shelters, raised beds and timely harvesting essential in Dorset.

Do you feed during flush?

Q
Which pruning method works best here?
A
Verified answer
Selective defoliation and early topping followed by LST keeps the canopy even and reduces mould risk in humid seasons.

What indoor humidity do you aim for?

Keep relative humidity around 40-50% in flower and lower if possible during late bloom to deter botrytis.

Any Dorset-specific tips?
