Let’s get started!

Grows Well With
Hydroponic Green Beans
Green Beans do great in Hydroponic systems! If you have experience with growing plants in hydroponics, then this will be simple. The first thing you need to do is germinate your seed. Green Bean Seeds are larger than most other plant seeds. Many people like to germinate these in a wet paper towel.
After a few days, the seed will begin to sprout up. You will know it is time to transfer to your unit once the true leaves appear. After transporting it to your AeroGarden, keep an eye on the water. Green Beans are a heavy water drinker. After you have watered it, and given it the nutrients. All there is left to do is keep an eye out for it, raising the light as it grows taller. For Green Beans, you will need some type of support system. Whether that is a trellis, or some type of twine. I have listed my favorites from Amazon at the bottom of this page.

How did I grow the biggest beans in Hydroponic system:
Aeroponic Green Beans
The same rules apply to aeroponic systems. If you have growing towers, the green beans will do fine but be sure to get plants that like the same nutrients. Just keep in mind the size of the plant before starting to plant!
Indoor Green Beans
Indoor Green Beans are quite simple. You are able to grow them inside using an of these systems – hydroponics, aeroponics or even soil! Green Beans grow faster in the systems rather than soil.
To prune your green bean plants, it’s just like any other plant. If you are growing these in a smaller system , then you will need to prune more often to ensure that all the leaves are getting the correct amount of sunlight. There is such a thing as a sucker on the Green Bean plant, these look tiny leaves sprouting from in-between two stems. You will want to cut these off as they are useless to the plant, and just ends up sucking all the nutrients and water.
The great thing about growing inside is that you have to worry way less about pests getting into your plants. Pests that normally attack Hydroponic Green Beans are: Fungus Gnats, Aphids, Mites, and White Flied. To avoid these, keep all doors and windows closed, and wash your hands! You can also change your clothes (If you went outside with these on) to ensure that no pests will invade your plants.
Most diseases come from root rot which is not a problem with aeroponic and hydroponic systems.
However, indoor plants are still captative of getting a disease. The most common are: Powdery Mildew, Downy Mildew, Gray Mold, Iron Deficiency. To avoid these, make sure your water and nutrients is right, and the temperature in your room/grow room.
Tips & Tricks
- Slice the seed a bit for better and faster growth rate. Soak for about 8 – 12 hours, if you soak them for too long, then they could become mesh.
- You can also place the seed in water for a day to allow the seed shell to soften for make the germination process faster
- It is not required to self pollinate the Green Bean plants, but many growers like to shake the plant a bit just to make sure
- Check your water daily, as Green Beans are a heavy water drinker
Green Beans grow fast, a growers just uses the same nutrients of a tomato and are heavy feeders.
A lot of Green Bean Growers prefer to germinate their seed in a wet paper towel. They sprouted almost overnight, and the plants grew super fast. Rockwool isn’t a hit with Green Beans, just use a paper towel and a plastic bag
Try not to give the Green Beans too much nutrients, as they will not produce any beans.
If growing this plant in a smaller system, get a smaller bush type. This will help with space and lighting.
If your Green Beans are looking rather sad, add in a fan to allow more air flow and pollination.
Green Beans are a dark green leaf color, if you notice they are slowly becoming stressed, this is a lack of magnesium. To fix this, add in a little bit of Epsom Salt to the water.
Keep in mind when purchasing seeds, that you look at whether the seed is a Bush Bean, or a Pole Bean. These two grow two different sizes and will make a huge difference in your AeroGarden System. You may need some type of small trellis with the Bush Beans, as the plant will start to get heavy as it produces beans.
