Jumpstart Your Fall Garden Indoors with LED Grow Lights
Fresh Harvests Don’t Have to End When Summer Does.
Seattle, WA – 08/12/25 – As summer winds down, many growers think the season is over — but it doesn’t have to be. With the right indoor setup, you can start your fall crops early, get healthier transplants, and enjoy harvests long after the first frost.
Here’s how to set up your space, choose the right crops, and use Active Grow LED lighting for maximum results.
Choose the Right Fall Crops
Cool-weather vegetables and greens are your best bet for fall planting. They thrive in shorter days and cooler conditions, making them perfect candidates for starting indoors.
Top crops for fall starts:
-Kale, spinach, and Swiss chard Lettuce and salad mixes
-Radishes, carrots, and beets Broccoli and cauliflower
-Peas Garlic (start cloves indoors for an early root boost)
Create a Productive Indoor Grow Space
Your plants need consistent light, temperature, and humidity to thrive indoors. Here’s what we recommend:
💡 Lighting: Active Grow Integrated T5 or T8 LED Grow Lights – Energy-efficient, low-heat, and spectrum-optimized for strong, compact growth.
🌱 Shelving/Tent: 3-Tier Walden White LED Grow Tent – Keeps conditions stable, maximizes light efficiency, and fits multiple trays on each shelf.
💪 Trays: Heavy-Duty 1020 Trays + Humidity Domes – Keep seedlings organized and maintain moisture levels.
Light Your Crops for Success
Seedlings need plenty of bright, consistent light. Without it, they’ll stretch and weaken.
Seedlings: 16–18 hours of light per day
Near windows: 14 hours supplemented with LEDs
-Keep lights 3–6 inches above seedlings
-Use a timer to maintain consistent schedules
Seedling products we recommend:
Integrated Dual T5 or T8 LED Grow Lights (1–2 per shelf). For kits either the the Seeds & Starts or Microgreens & Herbs 3-Tier Walden White LED Grow Tent.
Products we recommend for larger transplants:
T5 HO 2.0 4FT LED Grow Light (high output for robust pre-transplant growth). For kits either the Veggies & Greens or the Flowers & Fruits 3-Tier Walden White Grow Tent.
Know Your Plant’s DLI (Daily Light Integral)
DLI measures the total amount of light a plant receives each day. Matching your lighting setup to your plant’s DLI needs can dramatically improve growth.
Examples:
Kale/Spinach seedlings → 6–10 mol/m²/d
Carrots/Radishes seedlings → 4–8 mol/m²/d
💡 Use our DLI Calculator to set the perfect light levels.
Keep Conditions Stable
Temperature: Most fall crops germinate best at 65–75°F
Humidity: Maintain moderate levels to prevent drying out
Water: Keep soil evenly moist, not soggy
Fertilizer: Begin feeding after first true leaves appear
Timing is Everything
Start seeds indoors 6–8 weeks before your first frost. This gives them a head start so they’re ready to transplant when outdoor conditions are right.
When transplanting, harden off your plants by introducing them to outdoor light and wind gradually over 7–10 days.
By starting your fall crops indoors now, you set yourself up for fresh, healthy harvests well into the cooler months. With the right lighting, controlled environment, and a little planning, you can enjoy homegrown greens, herbs, and veggies year-round. The future of growing is here—bring it into your home and taste the difference.
