Growing Hydroponic Fairy Tale Eggplants are a great use of pod space, and are super…
Growing Radishes in hydroponic or aeroponic systems is actually possible! It may seem a little odd at first, but I am here to walk you through the full process. Radishes are one of the fastest growing vegetables.
Let’s get started!
- Optimal PH: 6.0 – 7.0
- 840-1540 PPM
- Temp: 50 – 65 degrees

Surprising, these do great in hydroponic systems! The one thing to keep in mind is they are heavy water drinkers. When you plan to plant these in your system, attempt not to plant these with other plants that are also heavy water drinkers. A common problem with these, is having too much of a certain element, which usually ends up being nitrogen.
- Ready to eat in about 25 – 30 days.
This plant tends to be somewhat a challenge but many growers end up with great results. The key to growing this plant is that there will be different nutrient solutions throughout the growing stages. When starting radish, you will need a basic grow nutrient. This encourages the green top growth. After the tops are developed, usually around the second week, switch to a nutrient for the root.
Before we get into all the details, I need to mention that IT IS possible to grow these in Hydroponics, and the Iharvest. Just keep in mind that it is 1 radish per pod, and you will need to harvest them before they get too big to get them out of the hole. If this does happen, you may need to tear apart your Net Cup to remove the vegatable.
The light requirement is about 8 – 10
Hydroponic Radish – Will it Kratky?
Aeroponic Radishes are actually quite simple, just like when growing them hydroponically. Follow the same regulations, and you will have Aeroponic radishes in no time.
Pruning will allow the plant to focus most of its energy on the new fruits and stems. Prune the stems and leaves that don’t look as healthy as the others. You can simply eyeball it, and pick and choose which ones you want to keep growing. Remember, the green leaf’s are edible, so after you clean them, you can place them in a nice green salad! These are the Microgreens of the plant!
Even though Radishes are easier to grow, there are still a few pests you will need to keep an eye out for. If you do see any, you can use a Neem Oil to get rid of them quickly.
Keep in mind, it is less likely to attract diseases in the Hydroponic and aeroponic growing systems, just like the pest.
However, you may come across a few diseases. Such as Clubroot, Downy Mildew, White Rust, Black Root, and Scab. Keep an eye on your plants as they are growing to prevent these.
Tips & Tricks
- The green leaves are edible! Place them in a salad, or a sandwich
