Grow Info

This strain is actually very easy to grow and one of the more beginner-friendly plants. It has a very good yield and harvest and the only thing the plant requires in abundance is water and sunlight while it’s protected from rain and humidity. The only problem which isn’t much of a problem because it’s easily solved is that the buds can get so heavy that you’ll need to either harvest them or build some sort of support, so the branches don’t break. It’s definitely worth growing as the demand is high and it’s very easy to maintain and keep happy.

Critical Mass grows quite tall but it can be grown both indoors and outside and in both situations, it gives a generous harvest. When grown indoors, the plant flowering time is around 8-9 weeks, which is an average length and the yield it will give is about 27 ounces per square meter. When grown outside, you’ll need to make sure that you’re in a Mediterranean climate for the plant to flourish and the yield it will have will be about 21 ounces per one plant. The flowering time outside is usually somewhere in the middle of September.
