You can spend $300 on a countertop unit with an app. You can also spend $15 and grow the same basil. This page is the second option, itemised.
The $15 starter kit (one plant)
| Item | Typical price | Why you need it | Cheaper alternative |
|---|---|---|---|
| Wide-mouth 32 oz mason jar | $3 | The reservoir. Wide-mouth so a 3-inch net pot sits on the rim. | A jar you already own, or a 2-litre bottle for free |
| 3-inch net pots, 10-pack | $5 | Holds the plant and medium above the water. | A plastic cup with holes melted or cut in it |
| Clay pebbles, 2L bag | $5 | Inert root support. Reusable indefinitely after rinsing. | Rockwool cubes, or perlite in a fine-mesh pot |
| Hydroponic nutrient, small bottle | $8 to $12 | The plant food. Non-negotiable. | No real substitute. Do not use garden fertiliser. |
| Total | $15 to $25 | Enough for several jars, not just one |
The next $30 (four plants, active system)
| Item | Typical price | Why | Money-saving note |
|---|---|---|---|
| Food-grade 5-gallon bucket and lid | $0 to $8 | The DWC reservoir. | Restaurants and bakeries give these away. Just ask. |
| Aquarium air pump, tubing, air stone | $10 to $15 | Oxygenates the solution and roughly doubles growth rate over passive. | Buy from the pet aisle, not the hydroponics shop. Identical hardware, lower price. |
| pH test strips | $5 | The single most useful measurement you can take. | A liquid drop kit at $8 lasts far longer per dollar. |
| Mechanical outlet timer | $5 | For a grow light. Removes the most common lighting mistake permanently. | Only needed if you use a lamp. |
| Running total | $35 to $55 | A one-plant jar and a four-plant bucket |
Where spending more is genuinely worth it
- A digital pH pen ($15 to $25) over strips. Once you run several systems, reading colours against a chart every week gets old and imprecise. This is the first upgrade we would make.
- A better grow light, if you have no good window. Light is the usual limit on indoor growth. A $35 light in a dark room does more for your yields than any nutrient upgrade.
- More net pots and pebbles. Boring, but the cheapest way to multiply output is more containers, not better ones.
What to skip in your first year
| Item | Typical price | Why skip it for now |
|---|---|---|
| All-in-one countertop system | $150 to $300 | You pay a large premium for a pump, a light and proprietary pods. Build two DIY systems first and then decide whether you still want one. |
| Water chiller | $100+ | Solves a problem most home growers do not have. Move the reservoir out of the sun instead. |
| pH Up and pH Down bottles | $15 | White vinegar and baking soda do the same job at this scale for pennies. |
| Nutrient boosters and additives | $20 to $60 | A complete base nutrient already contains all seventeen elements. Additives optimise the last few percent, which is not where your yields are being lost. |
| CO2 equipment | $50+ | Only relevant in a sealed, high-intensity grow room. |
| EC/TDS meter | $15 to $25 | Useful eventually. For a first grow, mixing at the label rate and watching pH is enough. |
