The One-Plant Wonder: Maximizing a Single Cannabis Plant in Rhode Island
In Rhode Island, adults 21+ are allowed to grow up to 6 cannabis plants, but only 3 can be mature at one time and many home growers opt to keep it simple with just one robust indoor plant.
Think one plant can’t give you a big return? Think again.
With the right techniques, a single cannabis plant can produce over a half-pound of top-shelf bud and it all starts with smart planning, the right tools, and a little creative TLC.
Why Grow Just One Plant?
Whether you’re short on space, working with a tight budget, or just want to stay within the legal minimum, growing a single plant can be:- Easier to manage
- Less expensive
- Discreet and low-odor
- A perfect learning experience
Step 1: Choose the Right Strain
For a one-plant setup, pick a strain that:- Responds well to training
- Produces dense colas
- Has strong genetics and mold resistance
- Grows well indoors
Great Options for RI Indoor Grows:
- Blue Dream – Easy to train, high yield
- Gorilla Glue #4 – Potent and bushy
- Granddaddy Purple – Compact with heavy buds
- White Widow – Great for smaller spaces and forgiving of mistakes
Step 2: Maximize Your Grow Space
Even if you’re growing in a closet or tent, you can optimize the space.- Ideal tent size: 2'x2' or 2'x4' for one plant
- Lights: 150W–300W LED full spectrum grow light
- Container: 5-gallon fabric pot with saucer
Make sure you have:
- A carbon filter to control odor
- An oscillating fan to keep air moving
- A humidifier or dehumidifier depending on the season
- A timer for your lights (18/6 for veg, 12/12 for flower)
Step 3: Train Your Plant Like a Pro
Training is the secret to massive yields from a single plant. These methods help shape your plant into a wide, even canopy of buds.Low Stress Training (LST)
- Use twist ties to gently bend the main stem sideways
- Keep tying down new tops to promote horizontal growth
- Helps light reach all bud sites
Topping
- Cut off the tip of the main stem after the 4th–6th node
- Forces the plant to grow two main colas instead of one
SCROG (Screen of Green)
- Place a net above your plant and weave branches through as they grow
- Creates a flat, even canopy perfect for maximizing light
Step 4: Feed for Success
Use a balanced nutrient schedule appropriate for each growth stage:- Vegetative stage: High nitrogen (N), moderate phosphorus (P), and potassium (K)
- Flowering stage: Low nitrogen, high phosphorus and potassium
Step 5: Patience During Flower
Your one plant will really bulk up in the final 4–6 weeks of flower. Don’t harvest early!- Watch trichomes with a jeweler’s loupe
- Look for mostly cloudy with some amber for a strong effect
- Let the buds ripen fully for best flavor and potency
Step 6: Dry & Cure Like It Matters (Because It Does)
Don’t let all your work go to waste - proper drying and curing brings out the flavor, aroma, and potency.- Dry in a dark room at 60–65°F and 50–60% humidity
- Hang branches or lay buds on a rack with air circulation
- Once stems snap (not bend), trim and move buds to glass jars
- Cure for at least 2–3 weeks, burping jars daily to release moisture
Final Yield: What You Can Expect
With good genetics, proper training, and the right indoor setup, your one plant can yield:- 4 to 10 ounces of dried, usable bud
- Trim for edibles or extracts
- Stems for compost or teas
