About Blackwater Og

Blackwater Og is an indica-dominant hybrid offering dense, resinous buds and a pronounced earthy-diesel aroma. It suits intermediate growers prepared to manage humidity and timing, performs well indoors and can be grown outdoors in cooler UK regions with planning to avoid a short outdoor growing season.

Grow Difficulty:

Blackwater Og suits intermediate growers who can manage humidity and precise feeding. In a short outdoor growing season you will need to start early and monitor trichome development closely.

Flowering Time:

Flowering usually completes in 8 to 10 weeks under controlled conditions. Outdoor growers should plan harvest timing carefully to avoid autumn weather delays.

Yield:

Yield is moderate with dense, sticky buds rather than huge bulk. Careful canopy management and humidity control can improve bud weight.

Height:

Plants develop a medium, compact structure with sturdy branches that support heavy colas. They are manageable in smaller gardens and well-suited to training techniques.

Environment:

Indoors Blackwater Og thrives under controlled humidity and regular training and benefits from SCRoG or topping. Outdoors in Lincolnshire plants can reach a useful size but will need protection from autumn rains in Lincolnshire to avoid mould.

Climate:

Growing Blackwater Og in Lincolnshire requires strict timing because of the short outdoor growing season. Start under cover, harden off early and aim to finish flowering before autumn rains arrive in a short outdoor growing season.

Q
Any tips for trimming to reduce mould?
A
Verified answer
Remove inner fan leaves and open up the canopy early to improve airflow, but do it gradually to avoid shocking the plants.

What training worked best for yield?
A
Verified answer
A combo of topping and low-stress training produced even colas and better light distribution indoors.
Common question Posted by Urbanseedbank Answered
Q
Did you see much terpene loss from wet weather?
A
Verified answer
Somewhat yes; prolonged damp reduced the diesel top notes, so dry and cure quickly after harvest to preserve aroma.
Common question Posted by Urbanseedbank Answered
Q
Would you grow it again in Lincolnshire?
A
Verified answer
