The Complete Beginner's Shopping List

Everything you need for your first hydroponic build. Start growing fresh herbs and greens for under $50. No experience needed.

Why This List?

Most "starter kit" lists online include 30+ items and cost $200+. You do not need all that. We built this list around the Kratky method -- the simplest hydroponic technique that uses no pumps, no electricity, and no timers. Just nutrient solution, a container, and sunlight.

Setup time: ~15 minutes  |  First harvest: 3-4 weeks  |  Total cost: under $50

Your First System

Mason Jar Hydroponic Herb Garden Kit

6 self-watering mason jars, 6 planting baskets, 6 pre-sown growth plugs, 6 absorbent cores

Tip: I keep a set of these on my kitchen counter year-round. Zero maintenance, no pump, no timer. Just top off the water when it gets low.

Budget alt: Any wide-mouth mason jar works. Wrap it in foil to block light, cut a hole in the lid for the net cup, and you are in business for under $5.

Wide-Mouth Mason Jars (Quart)

32 oz wide-mouth mason jars with lids, 12-pack, perfect for Kratky method

Tip: Check your kitchen before buying. Most people already have mason jars sitting in a cabinet. Any wide-mouth jar works for Kratky.

3-inch Net Cups

VIVOSUN 3-inch heavy-duty net cups with plant labels, 25-pack

Budget alt: You can make DIY net cups from plastic drinking cups by poking holes in the sides and bottom with a soldering iron.

Nutrients & Media

Hydroponic Nutrients (Flora Series)

General Hydroponics Flora Series 3-part liquid nutrient kit, 1 quart each

Tip: I have tried a dozen nutrient brands over the years. The Flora Series keeps winning because the three-part system lets you adjust ratios for any crop without buying separate formulas.

Budget alt: Masterblend 4-18-38 is a great dry nutrient option at a fraction of the cost per gallon. Our Nutrient Calculator supports both brands.

Seed-Starting Plugs

General Hydroponics Rapid Rooter seed-starting plugs, 50-pack

Tip: Rapid Rooters have the best germination rate of anything I have tested. Seeds sprout in 2-3 days and the roots grow right out the bottom into your net cup.

Budget alt: Rockwool cubes or even a damp paper towel will germinate seeds. Rapid Rooters are a convenience, not a necessity.

Expanded Clay Pebbles (Hydroton)

Hydroton original expanded clay pebbles, 4 liters, lightweight, pH neutral

Tip: I rinse and reuse the same clay pebbles across multiple grows. They last practically forever and keep roots perfectly aerated.

Monitoring

pH & TDS Meter Kit

VIVOSUN digital pH meter + TDS/EC meter combo kit, 0.01 pH accuracy

Tip: If I could only buy one tool, this would be it. Most problems I diagnose in the Plant Doctor come down to pH being off. Checking takes 10 seconds and saves weeks of frustration.

Lighting

Full-Spectrum LED Grow Lights (2 ft)

24W full-spectrum LED grow light, 2 ft, linkable, 6500K daylight, 4-pack

Tip: These are what I use on my shelf rack builds. They link end-to-end so you only need one outlet per shelf. I have had sets running 16 hours a day for over a year with no issues.

Budget alt: A sunny south-facing window provides enough light for lettuce and herbs from spring through fall. Grow lights are only essential for indoor setups without natural light.

Programmable Outlet Timer

BN-LINK 24-hour mechanical outlet timer, 15A, grounded, ETL listed

Tip: Consistent light schedules matter more than most beginners realize. Set it once and your plants get the same photoperiod every day without you remembering to flip a switch.

Seeds

Culinary Herb Seeds Variety Pack

12-pack heirloom herb seeds — basil, cilantro, mint, parsley, dill, chives & more

Tip: Start with basil and mint. They are nearly impossible to kill and you will have fresh herbs within 3 weeks. Once you are hooked, try the rest of the pack.

Frequently Asked Questions

You can start a basic Kratky (passive) hydroponic system for under $50 using mason jars, net cups, nutrients, and seeds. A more complete setup with grow lights runs $50-$100.

The items on this page are everything you need. Skip the expensive kits until you know you enjoy it.

The Kratky method is the easiest hydroponic system. It requires no pumps, no electricity, and no timers. You simply fill a jar with nutrient solution, place your plant in a net cup, and let it grow.

It is ideal for herbs (basil, cilantro, mint) and leafy greens (lettuce, spinach). Take our quiz to find the best system for your goals.

It depends on your space. A sunny south-facing window (6+ hours of direct light) works for herbs and lettuce. For consistent year-round growing, or if you lack window space, a basic 2-foot LED grow light ($25-40) makes a big difference.

We included a grow light recommendation in the list above for growers who want the best results.
