SCROG vs SOG: Choosing the Right Canopy Method

ScrOG (Screen of Green) trains a few plants under a horizontal net to spread one wide, even canopy, maximizing yield per plant over a longer veg. SoG (Sea of Green) packs many small plants close together and flowers them early, maximizing yield per square foot with faster turns. ScrOG suits few plants; SoG suits many.

The core difference between ScrOG and SoG

We run a Colorado nursery, and these two methods answer the same question in opposite ways: how do you fill a canopy? ScrOG uses plant count of one or a few and stretches each one across a screen so every bud site sits at the same height in strong light. SoG uses many plants, each grown small and flipped early, so the sheer number of tops fills the space.

Both aim for an even, light-filled canopy. ScrOG gets there through training and time. SoG gets there through numbers and speed. Your legal plant count, space, and patience decide which fits.

ScrOG versus SoG compared

Factor	ScrOG	SoG
Plant count	Few, 1 to 4 per light	Many, 9 to 16+ per light
Veg time	Longer, 4 to 8 weeks	Short, 1 to 2 weeks
Training effort	High, weaving a screen	Low, minimal training
Yield per plant	High	Low per plant, high per area
Best for	Low plant-count limits	High plant-count allowance
Turnaround	Slower	Faster cycles

How to run a ScrOG

1. Set a horizontal net 8 to 12 inches above the pots.
2. Veg 1 to 4 plants until they reach the screen, topping and using low-stress training to encourage lateral growth.
3. As branches poke through, tuck and weave them horizontally to fill open squares evenly.
4. Keep weaving until the screen is roughly 70 to 80 percent full, then flip to flower.
5. Tuck for the first 1 to 2 weeks of stretch, then let the colas grow up through the net.
6. Lollipop everything below the screen so energy goes to the canopy.

How to run a SoG

1. Start many uniform plants, ideally clones so they grow at the same rate.
2. Grow them in small pots and veg just 1 to 2 weeks.
3. Space them close, roughly 1 plant per square foot.
4. Flip to flower early so each plant makes one dominant central cola.
5. Do minimal training. The canopy fills from plant count, not from spreading each one.

Which one should you choose?

Pick ScrOG when your plant count is limited, when you want to squeeze maximum yield from a handful of plants, and when you have veg time to spare. Pick SoG when you can run many plants, want faster harvests, and prefer minimal per-plant training. SoG's biggest advantage is uniformity, which is why clones shine here. Identical genetics grow at the same pace and finish together.

ScrOG rewards patience and a steady hand at the screen. SoG rewards good logistics and a reliable clone supply. Many growers start with SoG for simplicity, then graduate to ScrOG once they want more control. For strain choices, browse our strain directory.

Frequently asked questions

Does ScrOG or SoG yield more?

Per square foot, they land close when done well. ScrOG concentrates yield in fewer plants over longer veg, while SoG spreads it across many plants with faster turns. Over a year, SoG can produce more total harvests because cycles are shorter. Your plant-count limit and available time usually decide which is more practical.

Which method is better for beginners?

SoG is simpler because it needs little training, just many uniform plants flipped early. ScrOG demands consistent weaving and canopy management over several weeks. Even so, ScrOG teaches you a lot about plant training. Beginners with a low plant count often learn ScrOG out of necessity and do fine with patience.

Do I need clones for SoG?

Clones are strongly preferred. SoG depends on uniformity, and clones from one mother grow at the same rate and finish together, giving you an even canopy. Seed plants vary in size and timing, which breaks the sea-of-green effect. Freshly rooted clones are the reliable way to fill a SoG evenly.

Can I combine ScrOG and SoG?

Loosely, yes. Some growers run several plants under one screen with tighter spacing, borrowing from both. Purists keep them separate, but the methods share a goal of an even, well-lit canopy. If your plant count sits in the middle, a hybrid approach can work with some experimentation.

Both methods start with strong, uniform genetics. Browse our cannabis clones for sale to fill your screen or your sea with freshly rooted plants.
