Grow tent size, how many plants to grow, and what to expect for yield

Yield depends on canopy area, plant density, cultivar, light and growing conditions. A 4 by 4 foot tent may be filled by a few large plants or several smaller ones. Similar canopy coverage doesn’t guarantee the same yield, so treat this comparison as space planning.

Starting point for plant count

These are common starting points. More plants means less time to fill the space, but more watering and more humidity.

What to expect for yield

Match the light to the canopy instead of assuming extra plants alone will raise yield. Research on indoor cannabis found yield and flower density rise as light intensity rises. More light also costs more and can cause stress. Exact amounts depend on genetics, light, skill and tent. Many first grows land well below the best numbers people post, so plan on learning, not setting records.

Wet weight isn’t final weight

Fresh buds are mostly water, and a large share of fresh weight is lost during drying. The exact proportion depends on starting moisture, trimming and final moisture, so don’t use a fixed wet-to-dry conversion as a yield guarantee.

Tent height

Pots, hanging gear and the gap between light and plant eat up a lot of height. Buy the tallest tent your space allows, and plan to train plants wide, not tall.
