How to grow GG #4 using grow lights

It’s a great strain to grow indoors, producing large central stems that grow bigger than most of its branches. It grows super-fast, so you’ll need to take care with how long you let it grow for before flipping the lights to the flowering period. You shouldn’t grow it for any longer than 20 days before switching to 12/12h; if you let it go for too long it may grow over 1.4m tall, which can be awkward to control indoors. In order to obtain the best possible results, we recommend growing 12 to 16 strains per square meter, which can produce over 400g of potent weed. It takes around 60-70 days to fully flower.

How to grow GG #4 outdoors

Outdoors it produces compact buds from top to bottom, and they tend to end up covered in a thick layer of THC-rich resin. It has an open structure that allows light and air to get in to the center of the plant, which is great if you live somewhere where it tends to rain a bit more than usual. It can reach up to 2.5m easily when grown in the ground, which can be an issue so you may want to train it using stakes or a trellis if possible. You’ll need to wait until the start of October to harvest this strain, and some plants may even take until the end of the month.
