About Runtz Smalls

Runtz Smalls is a compact hybrid selected for dense, resinous buds and an unmistakable sweet terpene profile. It performs well in controlled greenhouse environments and rewards attentive growers with consistent potency and flavour.

Grow Difficulty:

Growing Runtz Smalls in a moist western coastal climate requires strict humidity control and strong airflow. In my Surrey greenhouse those measures are essential to prevent mould and keep plants vigorous.

Flowering Time:

Flowering usually completes in eight to ten weeks under stable conditions. Trichome production tends to peak toward the end of that window.

Yield:

Yield is moderate for a compact plant and responds well to training techniques. Under a well-managed greenhouse it can deliver respectable weights per square metre.

Height:

Plants remain short to medium with a bushy, branchy structure ideal for SCROG or LST. Colas form thick and resinous, keeping the canopy compact.

Environment:

In my Surrey greenhouse Runtz Smalls benefits from controlled light cycles and humidity management. Outdoors in Surrey it finishes reliably when sited in a sheltered, sunny spot away from prolonged rain.

Climate:

Growing Runtz Smalls in Surrey requires attentive moisture management because the moist western coastal climate increases fungal risk. A ventilated greenhouse with dehumidification keeps buds healthy and reduces crop loss.

Q
Do you use CO2 in your Surrey greenhouse?
A
Verified answer
I don't for small batches; CO2 helps large sealed rooms but isn't necessary for modest greenhouse grows with good light.

Q
When do you start training?
A
Verified answer
I begin LST after the third node and top once to encourage a bushy canopy and multiple main colas.

How do you feed during flowering?

What signs tell you harvest is near?
