How do I control the height of my cannabis plant?

    I plan on getting a 4 foot tall grow box and my worries is that my og kush or northern lights will grow beyond 4 feet tall when I use an OPTIC 2 GEN3 COB LED GROW LIGHT 205Watt. Is there a way I can control how high I want the flower to go and then stop to where it will produce buds? As much as I love getting pounds of bud, I can't afford to have a marijuana plant the size of an oak tree.

    A cob light isn’t a good choice when heightbis an issue. They usually need around 18-24” above plants. Another 10” for your pot and you have a 14” plant

    It’s more or less the intensity of the light.

    They make these great qd boards that will get the job done for you.. and when a dimmable driver is used controlling light intensity is a breeze..

    some can be placed up high against the tent maximizing growth space.. (but 4’ is pretty short)..
