Here is a straightforward breakdown of the eight supplies every indoor grower needs, with specific product recommendations and realistic pricing.
Essential Supplies at a Glance

|---|---|---|
| Grow Light | Spider Farmer SF2000 | $200 - $350 |
| Grow Tent | AC Infinity Cloudlab 844 | $110 - $210 |
| Ventilation Fan | AC Infinity Cloudline T6 | $130 - $170 |

| Fabric Pots | VIVOSUN 5-Gallon 5-pack | $12 - $18 |
1. Grow Light
Your light is the single most important piece of equipment. LED panels have completely taken over because they run cooler, last longer, and use less electricity than older HPS setups. The Spider Farmer SF2000 draws about 200 watts and covers a 3x4 foot area during flower. It uses Samsung LM301B diodes, which are the current industry standard for efficiency.
Expect to spend $200 to $350 on a quality LED for a 4x4 tent. Cheaper options exist, but cutting corners on your light directly impacts your yield.
2. Grow Tent
A tent gives you a controlled environment that you can dial in for temperature, humidity, and light. The AC Infinity Cloudlab 844 is our top pick for 4x4 setups at $209. If you are on a budget, the Vivosun 4x4 at $109 works fine for your first couple of grows.
3. Ventilation
Plants need fresh air. An inline fan pulls stale air out of your tent while drawing fresh air in through passive intake vents. The AC Infinity Cloudline T6 is the quietest and most popular 6-inch fan on the market. It includes a built-in speed controller and can be automated with AC Infinity temperature and humidity controllers.
4. Carbon Filter
Cannabis plants smell. A lot. A carbon filter attached to your exhaust fan scrubs odor from outgoing air. The Phresh Filter 6x24 lasts about 18 months before the carbon needs replacing and handles the airflow from a T6 fan without restriction.
5. Growing Medium
Most beginners start in soil, and Fox Farm Ocean Forest is the go-to choice. It comes pre-loaded with enough nutrients to feed your plants for the first 3 to 4 weeks, which means less guesswork early on. A single 1.5 cubic foot bag fills two 5-gallon pots.
6. Nutrients
After your soil runs out of food, you need bottled nutrients. The General Hydroponics Flora Trio (FloraGro, FloraMicro, FloraBloom) is a three-part system that has been the standard for decades. Mix according to the feeding schedule on their website, and your plants will have everything they need from seedling to harvest.
7. pH Meter
Cannabis absorbs nutrients best when the water pH sits between 6.0 and 7.0 in soil. If your water is too acidic or too alkaline, plants will show deficiency symptoms even when nutrients are present. The Apera PH20 is accurate, reliable, and costs about $50. Calibrate it monthly with buffer solution and it will last for years.
8. Fabric Pots
Fabric pots promote air pruning of roots, which prevents root binding and encourages a healthier root structure than hard plastic pots. A 5-pack of Vivosun 5-gallon fabric pots costs under $18 and works perfectly for most grows.
Optional but Helpful
- Timer: A basic mechanical timer ($8 to $12) automates your light schedule
- Hygrometer: The Govee WiFi sensor ($15) tracks temperature and humidity from your phone
- Training clips: Low-stress training clips help shape your canopy for better light distribution
- Jewelers loupe: A 60x magnification loupe ($8) lets you inspect trichomes to time your harvest
Total Startup Cost
A complete indoor grow setup using the products listed above runs between $650 and $1,000 depending on which tier you choose for each item. The light and tent are where most of your budget goes. Do not cheap out on those two, and you can save on everything else without hurting your results.
