Browse our collection of hydroponic gardening guides. Whether you are setting up your first indoor system or scaling up an outdoor operation, you will find practical instructions to help you grow healthy fruits and vegetables year-round.
Getting seeds off to a strong start is the foundation of every successful hydroponic grow. Unlike soil gardening, hydroponic seed starting uses inert media that give you full control over moisture and nutrients from day one. This guide walks through the process from soaking your media to transplanting healthy seedlings into your system.
What You Need
Rockwool cubes, rapid rooters, or similar starter plugs
A seedling tray with a humidity dome
Seeds of your choice (lettuce, herbs, tomatoes, and peppers are great starters)
pH-adjusted water (5.5–6.0)
A spray bottle
A heat mat (optional but helpful for warm-season crops)
A grow light or bright windowsill
Step 1: Prepare Your Growing Media
If using rockwool cubes, soak them in pH-adjusted water (5.5) for at least 30 minutes before use. Rockwool is naturally alkaline, so this pre-soak brings it into the right range for seed germination. Rapid rooters and sponge plugs can be used straight from the package with a quick soak in plain water.
Strawberries are one of the most satisfying fruits to grow hydroponically. By moving established crowns from your outdoor garden into an indoor system, you can extend the growing season and enjoy fresh berries year-round. This guide covers the full process from selecting crowns to harvesting ripe fruit.
What You Need
A hydroponic system (NFT channels or vertical towers work best for strawberries)
Net pots and growing medium (clay pebbles or perlite)
Hydroponic nutrient solution formulated for fruiting plants
Healthy strawberry crowns from your outdoor garden (day-neutral varieties are ideal)
A full-spectrum LED grow light
pH and EC meters
Clean scissors or pruning shears
Step 1: Select and Prepare Your Crowns
Choose healthy, disease-free crowns from your outdoor strawberry patch. Look for plants with strong root systems and no signs of rot or pest damage. Trim any dead or damaged leaves and gently wash the roots to remove all soil. Soak the roots in clean water for about an hour before transplanting.
Tomatoes are a rewarding crop for outdoor hydroponic growers. With the right setup, you can produce large yields of flavourful tomatoes throughout the Canadian summer. This guide covers everything from choosing a system to harvesting ripe fruit.
What You Need
A Dutch bucket or drip irrigation hydroponic system
Large net pots or grow bags
Hydroponic nutrient solution formulated for fruiting plants
Tomato seedlings or seeds (cherry and beefsteak varieties work well)
Support stakes or a trellis
pH and EC meters
Step 1: Choose Your Location
Pick a spot that receives at least six to eight hours of direct sunlight per day. Shelter from strong winds is helpful, as tomato plants can be top-heavy once they start fruiting.
Lettuce is one of the easiest vegetables to grow hydroponically indoors. It grows quickly, requires minimal space, and thrives under basic grow lights. This guide walks you through the entire process from seed to harvest.
What You Need
A small hydroponic system (deep water culture or Kratky method work well)
Net pots and growing medium (clay pebbles or rockwool cubes)
Hydroponic nutrient solution formulated for leafy greens
A grow light (full-spectrum LED recommended)
Lettuce seeds (butterhead and romaine varieties are great starters)
pH testing kit
Step 1: Set Up Your System
Fill your reservoir with water and add the nutrient solution according to the manufacturer’s instructions. Aim for an EC of 0.8–1.2 for lettuce. Adjust the pH to between 5.5 and 6.5.
