In a crisis, food security isn’t just survival — it’s freedom. Start growing now.
When disaster strikes or systems fail, having the ability to grow food indoors can be the key to long-term survival. Whether you’re stuck in an apartment, a bunker, or a fortified homestead, indoor gardening allows you to produce fresh food, herbs, and even medicine year-round — without relying on the grid or outdoor conditions.
This guide will teach you everything you need to know to get started with a self-reliant indoor survival garden.
🧱 Indoor Gardening Methods
🌱 1. Soil-Based Gardening
Pros: Low cost, simple setup
Cons: Slower growth, soil pests
Recommended DIY Soil Mix:
- 1 part compost
- 1 part peat moss or coconut coir
- 1 part perlite or coarse sand
Container Ideas:
- Recycled buckets, plastic bins, or milk jugs
- Must have drainage holes and a catch tray
💧 2. Hydroponics (Water-Based Growing)
Grow plants without soil, using nutrient-rich water.
Pros: Fast growth, efficient
Cons: Requires nutrient and power management
Easy Method: Kratky System
- Passive hydroponics
- No pump or electricity
- Great for leafy greens (lettuce, basil, etc.)
🐟 3. Aquaponics (Fish + Plants)
Combine hydroponics with fish farming for a dual-purpose system.
Ideal Fish: Tilapia (tolerates poor conditions, fast-growing)
Grow Bed: Gravel or clay pellets
Power: Low-watt pump for circulation
DIY Tip: Use old IBC totes or barrels.
🔆 Lighting for Indoor Plants
Plants need full-spectrum light (400–700nm PAR range). In survival scenarios, energy efficiency is key.
Lighting Options:
- LED Grow Lights – low energy, effective
- T5/T8 Fluorescents – great for leafy greens
- DIY Reflectors – use foil, Mylar, or shiny surfaces
Light Duration:
- Greens: 12–14 hrs/day
- Fruiting plants: 14–18 hrs/day
🧪 Fertilizers & Nutrients
Essential Nutrients:
- N (Nitrogen): leaf growth
- P (Phosphorus): roots and flowers
- K (Potassium): plant immunity
DIY Organic Sources:
- Compost tea
- Crushed eggshells (calcium)
- Coffee grounds (acid-loving plants)
- Banana peels (potassium boost)
- Wood ash (potassium + pH buffer)
💦 Watering and Irrigation
Best Water: Rainwater or dechlorinated tap
Avoid: Overwatering = root rot
Low-Tech Irrigation:
- Wicking beds (cloth or rope system)
- Gravity drip (jug + tubing)
- Buried bottles near roots
🥬 Top Survival Crops for Indoors
| Plant | Days to Harvest | Notes |
|---|---|---|
| Lettuce | 30 | Fast, nutrient-dense |
| Spinach | 40–50 | Iron-rich |
| Kale | 60 | Cold-tolerant, highly nutritious |
| Radishes | 30 | Very fast-growing |
| Green Onions | 20–30 | Can regrow from scraps |
| Beans/Peas | 50–70 | Protein source |
| Tomatoes | 75–90 | Fruiting, sauces |
| Sweet Potatoes | 90–120 | High-calorie, can grow in bins |
🌿 Medicinal Plants to Grow Indoors
| Herb | Uses |
|---|---|
| Aloe Vera | Skin healing, burns |
| Mint | Nausea, digestion |
| Chamomile | Sleep, calming |
| Lemon Balm | Antiviral, stress relief |
| Basil | Anti-inflammatory, culinary |
| Thyme | Antiseptic, immune support |
🔌 Power & Backup Options
Grow lights and pumps require power. During an emergency, plan ahead.
Power Solutions:
- Solar generator + battery bank
- Deep-cycle batteries + inverter
- Manual wicking systems as backup
- Thermal mass (barrels of water) to regulate temperature
🌾 Seed Selection & Storage
Choose:
- Heirloom or open-pollinated seeds
- Non-GMO varieties
- Compact or fast-growing cultivars
Storage Tips:
- Cool, dark, airtight containers
- Add desiccants (like rice or silica gel)
- Use vacuum sealing if possible

🛠 Reclaimed Survival Supplies
Look in:
- 🧴 Dumpsters/landfills: bins, buckets, PVC pipe, aquarium gear
- 🧊 Old coolers or washing machine drums: great planters!
- 🔋 Batteries, inverters, light fixtures (if tested safe)
Nature offers:
- 🪵 Wood ash (potassium)
- 🍂 Fallen leaves (mulch/compost)
- 🪨 River rocks (grow media)
🐛 Natural Pest Control
- Neem oil (fungus and pests)
- Sticky traps (flies, gnats)
- Diatomaceous earth (crawlers)
- Companion planting (mint repels aphids)
- Manual removal + isolation
✅ Final Tips
- Label and date all plantings
- Practice indoor crop rotation
- Use vertical space (shelves, hanging pots)
- Journal your observations
- Always store backup seeds and tools
