Frequently Asked Questions

What is hydroponics?

Hydroponics is a soilless method of growing vegetables, fruits and flowers. Hydroponic plants’ roots are suspended in the liquid solution of all the nutrients plants need to thrive and supplied with oxygen and light. Often grown inside a greenhouse or grow tent, hydroponics can also be set up outdoors.

Is hydroponic gardening expensive?

Not necessarily. Setting up your hydroponics system at home is simple and inexpensive. All you need is a hydroponics kit, and with knowledge and perseverance, you can have a low-maintenance, cost-efficient and time-saving hydroponic garden. Imagine saving dollars on groceries by simply growing herbs at home! If you’re ready to start your hydroponic growing system, shop our kits today.

Can I grow different plants in one hydroponics system?

Yes. You can grow different crops in the same hydroponics system, but these plants must have similar nutrient requirements. Remember that some plants need high levels of nutrients, while others can thrive in a low-nutrient environment. Don’t hesitate to talk to our team if you need more guidance on picking hydroponic crops and supplies.

Can I use hydroponics outside?

Absolutely! Hydroponic systems are typically contained indoors in grow tents or greenhouses, but you can also create an outdoor hydroponic garden. You will likely need the same hydroponics supplies as an indoor setup, but your hydroponic garden will rely on natural sunlight instead of a controlled light source.

Do I need lights?

While not always necessary, grow lights can be a game-changer for most indoor hydroponic gardens. We stock a range of options here at Discount Hydro, from budget-friendly fluorescents to high-tech LEDs.

If you’d rather leave lighting up to the sun, go for an outdoor hydroponics setup. Still unsure which lighting source is right for your plants? Our team of hydroponic lighting experts is here to help! Browse our huge range of hydroponics lighting or reach out to our team to point you in the right direction.

Is hydroponics safe?

Yes. Hydroponics is perfectly safe. Hydroponically grown produce typically has the same nutritional value as traditional soil-grown produce. Hydroponic gardening also has the benefit of often requiring fewer pesticides, thanks to greenhouses, grow tents, and indoor hydroponic systems shielding plants away from pests and insects. Moreover, hydroponic plants don’t need traditional fertilisers as they’re suspended in water—not soil. That makes them safer and better for the environment.

Is hydroponics difficult for beginners?

Not at all! While it may seem complicated at first, hydroponics can be quite simple. We offer beginner-friendly kits and plenty of guidance to help you get growing.

Which plants can be grown hydroponically?

Hydroponic systems are perfect for growing a whole range of fruits, vegetables, herbs and plants, including lettuce, leafy greens, capsicum, tomatoes, basil, mint, strawberries—you name it! Some vegetables less suited to hydroponic gardening include carrots, turnips & onions, which all need a lot of space to spread their roots.

What hydroponics supplies do I need to get started?

Ready to get started on your hydroponics? You will need a hydroponic system, a grow medium (grow tent or greenhouse for indoor gardening) and hydroponic plants. You will also need liquid solutions, a light source & an EC and a pH meter.
Your hydroponic needs will largely depend on your goals, like how much and which crops you want to grow. Contact our friendly and knowledgeable team for personalised hydroponic advice. You can also read our helpful how-to guides.

How often do I need to change the nutrient solution?

The frequency depends on factors like your system type, plant size, and growth stage. The rule of thumb is to change your nutrient solution every one to two weeks. But don’t fret—your plants will usually let you know if they’re no longer happy with their ‘food.’ Plus, we’re always here to help you fine-tune your nutrient schedule.

Can I mix hydroponic nutrients?

Yes. While you can mix your nutrients, it requires careful calculation and a good understanding of plant nutrition. It’s usually easier and safer for beginners to use pre-mixed commercial hydroponic nutrients. As you gain experience, you can experiment with custom mixes.

Is it safe to use tap water for my hydroponic system?

While you can use tap water for your hydroponic garden, it’s best to test it first. Many municipal water sources contain chlorine and other additives that can harm plants. Let tap water sit out for 24 hours to ensure chlorine evaporates, or use a water filter. Feel free to chat with our team for more guidance about this topic.

Do I have to buy a grow tent?

We highly recommend adding a grow tent to your list of hydroponic supplies, especially if you want to garden under controlled lighting. A grow tent will give your crops and plants the best chance to thrive. It offers temperature control, making it suitable for locations that usually experience temperature fluctuations. It also keeps bugs and diseases at bay. More importantly, grow tents often have a reflective lining that helps ensure even light distribution. And let’s not forget that the small area created by a grow tent is much easier to manage. Simply put, a grow tent will help your plants thrive and save you from the problems often associated with traditional gardening.

How much space do I need for a hydroponic setup?

The beauty of hydroponics is its flexibility! You can start with something as small as a windowsill herb garden or go all out with a full-room setup. Feel free to shop systems to fit every space, from compact countertop units to larger multi-plant setups.

How often should I check the pH and nutrient levels?

It’s recommended to check pH and nutrient levels (EC/PPM) daily, especially when you’re starting. As you gain experience, you may check every few days. Maintaining proper pH (usually 5.5-6.5) and nutrient concentration is vital for plant health.

What are the benefits of growing hydroponically?

Whether building a personal herb garden or planning to grow and sell crops, a hydroponic setup will suit and benefit you. Hydroponic gardening also requires minimal labour—no weeding, digging or worrying about pests. It’s also space-saving, so it is perfect if you live in an apartment or a smaller home without ample backyard space.
