A small cannabis grow typically costs $300 to $1,200 to set up indoors for two to four plants, plus about $40 to $120 per month for electricity and consumables while plants are growing. A simple outdoor grow in pots often runs $150 to $550 for the season. The range is wide because lighting, ventilation, and whether you start from seed or clone move the total more than anything else.

What drives the cost of a small grow
- Grow space. A 2x2 tent for one or two plants costs less to light and ventilate than a 4x4 tent for four to six plants.
- Indoor or outdoor. Outdoor grows skip lights, tents, and fans, but you give up control over weather and daylight hours.
- Light type. LED fixtures cost more up front and less to run. Older HID setups are cheaper to buy and heavier on the power bill.
- Seed or clone. Feminized seeds usually run a few dollars to about $15 each. Clones often cost more per plant but save weeks of vegetative time.
- Medium and nutrients. Bagged soil with dry amendments is the cheapest route. Bottled nutrient lines and coco coir cost more.
- Odor control. A carbon filter and inline fan add cost, and they matter if roommates, neighbors, or shared walls are a factor.

Complete Budget Cannabis Grow Setup Guide
- Grow tent (2x4 or 3x3): $80 to $250
- LED grow light: $120 to $500
- Inline fan and carbon filter: $80 to $220
- Fabric pots, saucers, trellis: $25 to $60
- Soil or coco plus nutrients: $60 to $200
- Timer, hygrometer, pH or EC meter: $40 to $120
- Seeds or clones: $40 to $150
- Small extras (jars, scissors, clip fan, gloves): $30 to $80
Added up, a first indoor setup lands somewhere between $475 and $1,580. A bare-bones build with a basic light sits near the low end, while a mid-range setup with a stronger fixture and better fan tends to land closer to $800 to $1,000.

Outdoor small grow costs
- Seeds or clones: $40 to $150
- Pots and potting soil or a raised bed: $40 to $150
- Compost, amendments, and nutrients: $50 to $150
- Stakes, netting, pest control, and watering gear: $30 to $100
That puts a small outdoor season at roughly $160 to $550. Electricity is not a line item, and sunlight does the work that an indoor light would.
Recurring costs per cycle
Power is the main ongoing expense indoors. A 200 to 400 watt LED running 18 hours a day draws about 4 to 7 kilowatt hours daily during vegetative growth, and slightly less during flowering at 12 hours. At common residential rates that comes out near $20 to $50 per month, with the inline fan adding a few dollars more. Nutrients add another $20 to $60 per cycle, and a replacement carbon filter every few rounds runs $30 to $70.
Ways to lower the cost of a small cannabis grow
- Start with a 2x2 or 2x4 tent and one quality light rather than a large kit you cannot fill.
- Compare complete kits against buying parts separately, since bundles sometimes beat piece-by-piece pricing.
- Grow in amended soil for the first cycle to skip bottled nutrient lines.
- Take clones from a plant you already own instead of buying seeds every round.
- Run lights overnight in summer to reduce cooling demand.
- Reuse pots, trays, and trellis netting across cycles.
Does it pay off?
After the first cycle, the equipment is already paid for, so each additional run costs mostly power and nutrients. That is where the math shifts, and a modest indoor harvest can bring the effective cost per gram down well below dispensary shelf prices, though yield depends on genetics, light intensity, and growing experience. Whether it pays off for you depends on local flower prices and how many cycles per year you actually run.
Before you buy equipment
Check your state's home cultivation rules, including plant count limits, whether a medical card is required, and any landlord or HOA restrictions. Costs are easy to estimate. Legal limits are not, so confirm them first, then build the budget around the plant count you are allowed to keep.
