Og Kush Strain
Experience the classic vibe with our premium Og Kush strain.
OG Kush indoor yield, the short answer
Plan for roughly 1.2 to 1.6 ounces per square foot of canopy, which is about 350 to 500 grams per square meter. Per plant, that usually means 3 to 4 ounces from a 3 to 5 gallon pot with four to six weeks of veg. Growers running strong LEDs, a full SCROG and a longer veg cycle can reach 5 to 6 ounces per plant, but OG Kush is not a bulk strain. She is a quality strain. Anyone promising a pound per plant indoors from seed is selling something.
What actually moves the number
Light and canopy footprint
Yield scales with the light you deliver per square foot, not with the wattage printed on the box. A 4x4 tent under 480 to 600 watts of quality LED is the sweet spot for this cut. Stretch the same light over a 5x5 and the grams per square foot drop fast. OG Kush rewards even coverage because her lowers are notoriously larfy when light does not reach them.
Veg time and training
This is where most of your extra weight comes from. A seed grown for three weeks and flipped will give you a single cola and maybe 1.5 ounces. The same plant topped once above the fifth node, trained flat under a net, and vegged for six weeks will fill a 2x2 footprint on its own and roughly double that. Expect about a 2x stretch during the first three weeks of flower, sometimes a little more on the stretchier phenos.
Pot size and root space
A 3 gallon pot is the practical floor for decent indoor numbers. Five gallons is better if you veg past five weeks. Roots that hit the wall early will stall the plant right as flowers start stacking.
Feeding
OG Kush is a picky eater, not a heavy one. She wants steady calcium and magnesium and she burns easily when the EC climbs. Feed at moderate strength, watch the leaf tips, and back off the moment they start to claw. Overfeeding does not add yield. It adds crisp leaves and a stalled finish.
Realistic yields by setup
- 2x2 tent, one plant, 3 gallon pot, 4 weeks veg: 1.5 to 2.5 oz
- 2x4 tent, two plants, 5 gallon pots, 5 to 6 weeks veg: 5 to 8 oz total
- 4x4 tent, four plants in a SCROG, 6 weeks veg: 10 to 16 oz total
- 4x4 tent, one large trained plant, 8 weeks veg: 8 to 12 oz
Flowering runs 8 to 10 weeks indoors depending on pheno, with most finishing around 9. Dense, rock hard buds are part of the appeal and part of the risk, because tight colas trap moisture.
What kills OG Kush yield
- Heat above 85F in late flower, which foxtails tops and thins them out
- Humidity above 55% with dense colas, which invites bud rot
- Pulling at day 56 with clear trichomes, which wastes the final swell
- No defoliation, so the bottom third stays pale and airy
- High EC from week 3 onward, which locks out calcium and stalls stretch
How I would push it
- Top once above node five, then keep the canopy flat with LST.
- Install a net at 8 to 10 inches and tuck for the first two weeks of flower.
- Strip the bottom third of each plant before flip so energy goes to the tops.
- Defoliate lightly at day 21 and again at day 42 if airflow is tight.
- Hold VPD in range, keep late flower humidity near 45%, and check trichomes with a loupe, not the calendar.
- Dry slowly at 60F and 60% RH for 10 to 14 days, then cure. Weight shrinks either way, but a proper dry keeps the terpenes that make this strain worth growing.
The honest bottom line
OG Kush will not out-yield a modern commercial hybrid, and chasing grams with this strain usually costs you the gas, pine and lemon notes people actually want. Treat 3 to 4 ounces per plant as a good indoor run, 5 to 6 as an excellent one, and put the effort into canopy management instead of bottle additives. Check your local laws before you start, and buy genetics from a source that names the cut, since OG Kush has more knockoffs than almost any strain on the market.
