HOMESTEAD HARVEST • THE INDOOR GROWING GUIDE
No soil.
Big possibilities.
The weather can turn cold. Your growing season can keep going.
Picture a little green corner of your home: fresh leaves, a soft glow, and something you grew yourself. Indoor hydroponics brings that idea within reach—even when the backyard garden is resting.
You don’t need to turn your house into a greenhouse to get started. Begin with one manageable setup, a crop you actually want to eat, and a routine you can keep. That first little garden is a place to learn, experiment, and enjoy bringing a bit of the homestead indoors.

01 / What is indoor hydroponics?
Hydroponics grows plants without soil, using a nutrient solution. Growing media can support the roots.
Water alone is not a complete feeding plan. Roots need oxygen, too; follow your system’s feeding and aeration instructions.
02 / Start with something you’ll love harvesting
Lettuce
Choose a variety suited to hydroponics and your available space.
Basil & herbs
Grow flavors you cook with. Check each herb’s light and temperature needs.
Leafy greens
Try kale, mustard greens, or Swiss chard. Leave room for mature leaves.
Fruiting crops need more light and space. Save tomatoes and peppers for a setup designed to support them.

03 / Build your green corner
Pick a setup you can maintain. Deep-water culture uses aeration, often an air pump. Passive Kratky growing uses an air gap; follow its water-level instructions.
Give your plants useful light. A bright window may help, but winter growing often needs supplemental lighting. For established hydroponic lettuce and herbs, University of Minnesota Extension recommends 12–14 total light hours per day as a starting point. Seedlings may need a different schedule. Follow your crop and equipment instructions.
Check coverage, not just brightness. A lamp that looks bright to your eyes may not deliver enough usable light across the plants. The fixture’s output, distance, and coverage all matter. Set the height using its instructions and adjust as your plants grow.

04 / Keep the routine simple—and measured
Choose a hydroponic nutrient formula compatible with your crop and system. Measure the recommended dose; extra fertilizer is not a shortcut. Add multi-part nutrients to water in the sequence specified on the label, keeping concentrates separate.
Two readings worth knowing
pH: Measures acidity. A common target for many hydroponic crops is 5.5–6.5, with exceptions. Use the range recommended for your plants.
EC: Indicates the amount of dissolved ions in the water. It helps track solution strength, but it cannot confirm that every nutrient is balanced. Follow a crop-specific target.
Record readings regularly, especially after mixing or changing the solution. Follow system instructions for topping up, solution changes, and cleaning. If growth stalls, check conditions before adding fertilizer.

05 / Make it part of your home
A growing corner can be beautiful as well as useful. Pair warm wood with green leaves, keep supplies neatly stored nearby, and leave enough room to reach the reservoir. Choose a location that works for daily life—not just a photo.
Before buying, write down your available space, the crop you want, and your budget. Compare what each kit includes, then account for ongoing supplies and electricity. Your first goal is a garden you enjoy tending.
Your first garden starts with one decision
Choose your space. Choose your crop. Make room for a little green. Whether it becomes a few fresh leaves for dinner or the beginning of a bigger growing habit, it starts right at home.
