🥬 Grow Fresh. Grow Clean. Grow with Confidence.

Take control of what's on your plate by growing your own lettuce and leafy greens at home with hydroponics.

When you grow your own, you know exactly:
🌱 What nutrients are being used
💧 What water your plants receive
🚫 Which pesticides are not being applied
🥗 When your lettuce was harvested—just minutes before you eat it

Hydroponic growing keeps your plants off the ground, reducing exposure to many soil-borne pests and diseases while producing crisp, clean greens year-round. With the right equipment and good growing practices, you can enjoy healthy, vigorous lettuce in as little as 30–45 days.

Growing your own food also gives you peace of mind. Whether you're feeding your family or simply love fresh salads, there's nothing quite like harvesting lettuce from your own home.

Is Heat stress causing grief for your plants?
In July, the peak summer heat dramatically accelerates moisture loss and induces plant dormancy. To protect your garden from severe heat stress, prioritize deep, early-morning watering, apply a 2- to 3-inch layer of organic mulch, and avoid applying heavy fertilizers or pruning, which can burn and stress delicate vegetation. Some natural products can help. Consider using seaweed or kelp to improve stress resistance. Silicon can be beneficial as it acts like armour to reduce water loss through transpiration. Natural fermented soil inoculants such as Terra Biosa can improve soil's ability to hold moisture and fortify the root microbiome.

BTK is highly selective, targeting only caterpillar pests. Because many common July hosts (like boxwoods) rarely host beneficial butterflies, you can safely spray without harming bees, humans, or pets.
July marks the emergence of the second generation of caterpillar pests (like the box tree moth) when larvae begin actively feeding. Spraying interrupts their life cycle before they can cause severe, rapid defoliation in late summer

🌱 Sprout Day is almost here!

On July 23rd we’re celebrating the tiny food with a huge nutritional punch.

You’re invited to join our 30 Day by adding a handful of fresh sprouts to your meals each day.

Sprouts are one of the most nutrient dense foods you can eat. They’re easy to grow at home, and they’re one of the simplest ways to add more fresh nutrition to your plate.

Over the next few weeks, we’ll be sharing why sprouts are so powerful, simple ways to eat them, and how you can join the challenge.

Get ready to sprout with us! 🌱
