About Jack The Ripper

Jack The Ripper delivers a fast, uplifting head high with a bright citrus terpene profile. It favours growers who can manage vertical growth and provide steady nutrition, and it performs best indoors or in sheltered outdoor sites where the season and humidity are controlled.

Grow Difficulty:

Growing Jack The Ripper in a short outdoor growing season can be moderately demanding because it stretches and needs time to bulk. It benefits from training and careful nutrient management to finish before cold or wet weather arrives.

Flowering Time:

Indoor flowering commonly completes in eight to ten weeks. Outdoors it needs the longest possible warm season to reach its full resinous potential.

Yield:

Yield potential is medium to high when plants get strong light and timely feeding. Proper screen-of-green or topping can significantly improve harvest size.

Height:

Plants tend to grow tall with extended internodes and long colas. They often require staking or pruning to avoid shading and to keep a manageable canopy.

Environment:

Indoors Jack The Ripper responds well to sea of green or training under high-intensity lights in Devon. Outdoors in Devon it rewards growers who give it a sheltered, sunny spot and an early start to the season.

Climate:

Growing Jack The Ripper in Devon requires careful timing because of the short outdoor growing season. Consider protected sites, early transplanting and the possibility of moving plants undercover to avoid autumn rains in Devon and secure a full finish in the short outdoor growing season.

Q
Did you top or scrog for better yields?
A
Verified answer
I topped twice and used a small SCROG net; it flattened the canopy and doubled the usable colas.

What feed schedule worked for you?

I ran a standard veg mix until week four of flower then switched to a bloom formula with a slightly increased PK boost.

Any advice on preventing mould in a humid Devon summer?

Keep lower branches trimmed, increase spacing and harvest any late flowers early rather than risk a soggy autumn.

Q
Which phenotype produced the best terpene profile?
