Frequently Asked Questions:

What variety of plants can be cultivated in the Stack & Sprout?

The Stack & Sprout is versatile, accommodating a vast selection of herbs, vegetables, and fruits. While the thrill of experimenting with new plants adds to its allure, we've already had success with the following:

  • Herbs: Basil, chamomile, chives, dill, lavender, lemon grass, mint, oregano, parsley, rosemary, sage, thyme (including common, lemon, caraway, wooly, elfin, silver, orange, lavender, broadleaf, among others) and more.

  • Vegetables: Arugula, beans (such as snap beans, green/string beans, lima beans, bush beans, fava beans, blay-eyed peas, among others), bok choy, broccoli, cabbage, cauliflower, cucumbers, dandelion, eggplant, kale, all varieties of lettuce, okra, bell peppers, hot peppers, chili peppers, squashes, rhubarb, spinach, sprouts, and more.

  • Fruits: Strawberries, tomatoes, tomatillos, etc.

  • Others: Flowers and leafy greens.

How tall are the Stack & Sprout units with 2 modules, and what is the height of each add-on module?

  • The starter package, which includes two modules, stands at approximately 30 inches in height and occupies a 1x1 square foot area. Each additional module measures slightly under 9 inches in height. The Base and water tank is approximately 7 inches tall. 

Regarding soil options, do you need to exclusively use the smart soil capsules, or can regular garden soil be used?

  • While technically feasible to use any growing material that fits inside the pods, we do not recommend traditional garden soil due to its potential for messiness or pump clogs. It's important to note that Stack & Sprout's smart soil capsules are specifically engineered to optimize the growth of herbs and vegetables. For the best results, we highly recommend using them.

How do I plant seeds in the Stack & Sprout system and care for them?

  • When planting seeds in the Stack & Sprout system, follow these steps:

    • While we'll provide guidance on recommended seeds and quantities, seed packs typically have specific instructions. For most plants, you'll need between 1 to 3 seeds.

    • After placing the seeds, cover them with the Stack & Sprout greenhouse cap. This helps in seed germination. Once the sprouting plant touches the cap's interior, it's time to remove it and allow the plant to grow freely.

    • Enhancing the water with nutrients can promote better growth. However, ensure you follow specific instructions provided with your nutrient solution to avoid over-concentration. If you see your plants wilting, it might mean that you’ve added too much nutrients. Simply empty the water using the valve at the bottom of the base, and then add fresh water. This will help to refresh the water concentration.

    • If you notice your plants starting to wilt, use the water release valve located at the bottom. Let out about 3/4 of the water, then refill your Stack & Sprout with fresh water. This can help rejuvenate your plants and ensure they get the nutrients they need.

How does the water pump work?

  • Stack & Sprout features a built-in water basin at the bottom with an automatic pump and timer. Once plugged in, the system waters your plants for you. The pump sends water to the top stack, which then trickles down to each pod like rain, ensuring even hydration.

How long does the water pump run for?

  • The water pump has an automatic timer that runs on and off in 20-minute intervals. This cannot be changed.

How do I access the water tank and what about a top cover?

  • You can easily access the water tank by removing one of the lower plant pods to test pH, add nutrients, and make adjustments. There’s also a drain valve at the bottom for easy water changes if you need to replace a larger amount. 

  • The unit includes a lid/cover for the top that can also be removed to fill with water. The lid also helps prevent debris from entering and maintain a clean growing environment. 

How large do the plants grow with this system?

  • Due to our efficient watering system, plants tend to grow larger and healthier. For taller plants, we are introducing a Support Ring to provide additional stability.

Does the spinning motion of the tower have any negative effects on the plant roots?

  • No, the spinning motion doesn't negatively impact the roots. The tower is designed to swivel smoothly at the base, ensuring no disturbance to either the roots or the integrated pump and plug. This feature is part of our innovative design.

Can Stack & Sprout be utilized indoors during the winter season?

  • While Stack & Sprout is primarily designed for outdoor gardening, it is possible to cultivate your garden indoors using our unit. In such cases, it's essential to install indoor UV plant lights above or around the Stack & Sprout to ensure your garden thrives and remains healthy throughout the winter.

  • Stack & Sprout does not currently sell grow lights, but you can find great affordable options online.

How do I maximize growth of healthy plants?

  • To help your plants thrive, keep the water tank topped up, use high-quality seeds, and ensure your system gets plenty of natural or artificial light.

  • The smart soil capsules are made with nutrients, so your plants stay lush and vibrant with minimal effort on your part.

  • However we do recommend the following to ensure healthy plant growth:

    Every time you re-fill a fresh tank of water on your Stack & Sprout, add to the water tank the following

    - 2 cap fulls of both the A & B HydraGrow's A/B Nutrients.

    - 30ml of a 3% FOOD-GRADE Hydrogen Peroxide to avoid algae growth in your unit
