About Mad Max

Mad Max is bred for energetic daytime use and commercial viability, combining sativa lift with stable resin production. It suits intermediate growers who can manage height and humidity and rewards careful training and timely harvests with robust terpene profiles and consistent potency.

Grow Difficulty:

Mad Max requires intermediate skills, especially for canopy control and timely pruning in a mild southern growing climate. Attention to feeding and pest checks will pay off with consistent resin production.

Flowering Time:

Flowering finishes in about 8 to 10 weeks indoors. Outdoors, it typically ripens by late September to early October in favourable areas.

Yield:

Yield potential is medium to high with proper light and nutrition. Indoor crops can reach up to 450 g/m² and outdoor plants can approach 400 g per plant under ideal conditions.

Height:

The plant grows tall with an open, airy structure and long internodes. Outdoor specimens commonly reach 120–180 cm if untrained.

Environment:

Indoors, Mad Max responds well to SCROG and low-stress training to maximise canopy efficiency in Fife. Outdoors in Fife it benefits from wind protection and good airflow to reduce the risk of bud rot.

Climate:

Growing Mad Max in Fife suits its preference when treated as a mild southern growing climate with careful humidity management. Occasional cool nights and wet spells mean greenhouse shelter or good ventilation is advisable to keep buds healthy.

Q
My buds showed some grey mould — what now?
A
Verified answer
Remove affected branches immediately, increase airflow, and inspect neighbouring plants; if widespread, harvest early and trim mouldy areas before curing.

Q
How did you train Mad Max indoors?
A
Verified answer
I used a combination of topping at the third node and a 60 cm SCROG net to create an even canopy and maximise usable light.
Common question Posted by Urbanseedbank Answered
Q
What light schedule worked best for flowering?
A
Verified answer
I switched to 12/12 for flowering and kept temperatures slightly cooler at night to encourage resin production and trichome density.

Q
Any tips for outdoor feeding in Fife?
A
Verified answer
Feed lightly but consistently, use a well-draining soil mix, and add seaweed or kelp teas to help plants cope with intermittent cool, damp weather.
Common question Posted by Urbanseedbank Answered
Q
Do you recommend drying indoors or in a shed?
A
Verified answer
Dry indoors in a cool, dark room with steady airflow and 50–60% relative humidity to preserve terpenes and avoid overdrying.
