But suppose nothing bad has happened. How will outdoor and indoor nugs compare then? There are still other risks in an outdoor grow operation.
These numbers are what you can hope to achieve under most favorable conditions and using powerful enough lights. Most of the time, this means a 600W HPS per each square meter. However, there’s no universal convention here. So, when you see numbers like 800 g/m², it probably means that you have to use a 1000W HPS per square meter to achieve such results.
Other Aspects of Bud Quality in Outdoor vs Indoor Plants
Grow lights, especially weaker ones, have a notoriously limited effective range. Here’s the inverse-square law in action: if you double the distance from light, its intensity reduces 4 times! This means that buds in the upper portion of an indoor plant can be huge and solid. At the same time, the lowers that are just a dozen inches down the branch are smaller and spongier, less mature and with fewer trichomes. It’s a good practice to trim away those popcorn buds in the earlier stages of flowering (a technique called lollipopping).
Or you can use a greenhouse the other way around: create an enclosed and sealed-off space, like a full-fledged indoor grow with all its bells and whistles, but with the sun serving as the source of light (either sole, or primary).
Outdoor vs Indoor Yield

Some growers begin germinating their cannabis plants indoors before transplanting them to a greenhouse when they start to grow and stretch during the vegetative stage. Naturally, the larger growing area of a greenhouse allows growers to cultivate a bigger crop and make significant savings on energy costs.
If you’re growing autoflowering strains, then the cannabis plants will automatically transition to the flowering stage as they mature without adjusting the lighting schedule. However, indoor growers will need to change to a 12/12 (12 hours of light/12 hours of darkness) lighting schedule for standard photoperiod strains.
Indoor growing is a relatively new practice of cannabis cultivation that only became popular during the time of prohibition. This method is a discreet way of producing quality marijuana that can thrive and produce sizable yields, even in the most inhospitable conditions. For this reason, indoor cultivation has become the go-to for many, especially those in regions where the climate is far from ideal.
Greenhouse Cultivation – A Bright Alternative
Strains like Tahoe OG and Northern Lights seem to be strong and capable of withstanding even sudden changes in the environment.
This is particularly true when considering where some of the most famous marijuana strains arise from; the Netherlands. This Dutch environment is in many ways almost inhospitable for the often warmth-loving cannabis crop. In California and Oregon, there is a region that is often termed “The Emerald Triangle”. This spot reaches extensively throughout Humboldt county, a region of California where the summer weather is usually sunny and dry, much like the Mediterranean, which is ideal for cultivating many different strains of marijuana.
Greenhouse vs. Indoor
One advantage greenhouse growing has over outdoor-grown cannabis is you can use light deprivation techniques to force plants into flowering earlier. By simply using blackout covers, you can control the amount of light your cannabis plants are exposed to.
By planting seeds outdoors, crops can photosynthesize utilizing purely the sunlight, a source of nourishment that is unmatched by any attempts in recreation, even by the greatest indoor light technologies currently being released. On some occasions, the presence of growth through natural sunlight is said to actually improve the flavor profile of the marijuana itself because terpene development is stimulated.
