Growing Tips for Grandpa Larry OG
Grandpa Larry OG is an easy-to-grow strain if you have prior cultivation experience. Grandpa Larry OG marijuana plants will thrive indoors and outdoors, but have an easier time growing indoors because of the ability to completely control the climate. If you choose to grow indoors, you will need to replicate a steady environment similar to a warm, Mediterranean-style climate. Grandpa Larry OG cannabis seeds grow into vibrant green and orange plants with smaller, potent buds that give off a skunky scent.
If you choose to grow outdoors, you will need consistent temperature and humidity to bring these plants to completion. Doing so will ensure that you grow healthy buds from the top of the plants to the buds closest to the soil. Having access to a greenhouse is the best way to give these plants the ideal outdoor climate without having to contend with unexpected outdoor variables — particularly important in Canada's variable growing seasons. These plants grow from short to medium and can reach around 75–180 centimetres tall. Because the plants reach a maximum indoor and outdoor height of around 180 centimetres, they are easy to grow in several smaller grow setups.
The ideal temperature for these plants is around 20–27°C and slightly cooler at night. Humidity levels should be kept around 40–60% during the vegetative growth stage and the flowering stage, but gradually lowering the humidity each week will help this plant thrive. Growing indoors will ensure that moderate humidity levels and moderate temperatures are consistent and maintained every day that the plants are in the growing stages.
Topping and Low-Stress Training (LST) methods are the best training techniques for this particular strain of cannabis. If performed correctly and at the right time, these techniques will promote bud production and increase final yields. LST helps manipulate the plants by tying down the branches to increase the size and density of the buds while allowing them to grow almost naturally. Topping will help keep the plants manageable by trimming the tops so the canopies don't overgrow. The Grandpa Larry OG strain requires an 18–20 hour light cycle to reach the vegetative growth stage. Changing the light cycle to a 12/12 cycle will induce the flowering stage of growth.
