Q
How do you handle humidity in late flowering?
A
I drop RH to around 45–50% and increase airflow, plus pick off any large fan leaves that trap moisture around bud sites.

About Gp20
Gp20 is a balanced hybrid bred from Gp10 x Gp11 that offers a clear, uplifting high followed by mellow relaxation. It performs reliably under indoor LED setups and can be grown outdoors in sheltered UK gardens with attention to wind and rain.
Grow Difficulty:
Growing Gp20 is intermediate and benefits from standard training like topping and LST. The variable British weather means extra vigilance for humidity and pests when moving plants outdoors.
Flowering Time:
Flowering completes in about 8 to 9 weeks indoors under stable conditions. Outdoor growers can expect a late-summer to early-autumn finish depending on the season.
Yield:
Indoor yield is medium to high with proper LED setups and training, often reaching around 400–500 g/m². Outdoor yields vary considerably and depend on seasonal conditions and shelter.
Height:
Plants are medium in stature with a bushy structure that suits SCROG or SOG methods. Canopy management keeps heights manageable for standard grow tents.
Environment:
Gp20 performs very predictably under indoor LED lighting and controlled environments in York. Outside in York it will fruit well in a sheltered spot but needs rain and wind protection.
Climate:
Growing Gp20 in York requires planning around the variable British weather to reduce mould and wind damage. Use covers during heavy rain and aim to harvest before persistent autumn storms.
