About Cleo

Cleo is a robust hybrid bred for balanced effects and practical growing in cooler, damper microclimates. It combines CLEO OG x NORTHERN LIGHTS parentage to deliver resinous buds, moderate to high THC and a citrus-pine flavour. Growers in Fermanagh will find it responds well to greenhouse protection and good airflow, and it rewards attentive mould prevention with consistent yields. The plant stays medium in height, flowers in eight to ten weeks, and is best cultivated by those familiar with humidity management.

Grow Difficulty:

Cleo is best suited to growers with some experience of humidity control. In humid greenhouse conditions it requires vigilant airflow and mould prevention to perform well.

Flowering Time:

Flowering normally completes in eight to ten weeks under stable conditions. Some phenotypes may need an extra week when allowed to bulk up.

Yield:

Yield potential is above average for a compact hybrid. Good canopy management and support can further increase bud weight.

Height:

Plants maintain a medium stature with dense lateral branching. They are manageable in both pots and ground beds without excessive stretching.

Environment:

Indoors Cleo does well in a controlled tent with steady environmental management. Outdoors in Fermanagh it benefits from greenhouse protection or a sheltered, sunny aspect to avoid prolonged damp.

Climate:

Growing Cleo in Fermanagh requires attention to persistent moisture and airflow when using humid greenhouse conditions. Provision for dehumidification, extraction and frequent disease checks is essential to protect developing buds.

Common question Posted by Urbanseedbank Answered
Q
My buds look slightly grey near the base, what now?
A
Verified answer
Check for early grey mould and increase extraction immediately, remove affected material and improve spacing to reduce humidity pockets.
Common question Posted by Urbanseedbank Answered
Q
Should I defoliate during stretch?
A
Verified answer
Remove only the largest fan leaves that block light and airflow; excessive defoliation can stress plants in a humid greenhouse environment.
Common question Posted by Urbanseedbank Answered
Q
What support do branches need?
A
Verified answer
Use stakes or netting to support heavy colas and prevent stem breakage as buds bulk up late in flowering.
Common question Posted by Urbanseedbank Answered
Q
How do I adapt flushing in a damp climate?
A
Verified answer
Flush with clean water but shorten the flush window slightly to avoid prolonged wet substrate; ensure pots drain freely and allow some dry-back between waterings.
Common question Posted by Urbanseedbank Answered
Q
When is the right time to introduce CO2 indoors?
A
Verified answer
Only consider CO2 once temperature, humidity and light are optimised and plants are in vigorous vegetative or early flowering stages for best benefit.
