Frequently asked questions

What plants can you grow hydroponically in Australia?

Almost any leafy green, herb, salad crop, fruiting vegetable, brassica, cucurbit or edible flower can be grown hydroponically in Australia. The easiest and fastest are leafy greens and herbs, like lettuce, spinach, kale, basil and coriander, which can be ready in a few weeks. Fruiting crops like tomatoes, capsicum and strawberries take longer, but they grow well indoors too.

What are the easiest plants to grow hydroponically for beginners?

Leafy greens and herbs are the easiest hydroponic plants for beginners. Lettuce, spinach, rocket, bok choy, basil and mint grow quickly and need very little fuss, so they are a forgiving place to start before you move on to fruiting crops like tomatoes or cucumbers.

Can you grow tomatoes and other fruiting vegetables hydroponically in Australia?

Yes. Tomatoes, capsicum, chillies, eggplant, cucumbers and strawberries all grow well hydroponically in Australia. They take longer than leafy greens and need good light and a bit of support as they grow, but indoors you can grow them right through the year, whatever the weather is doing outside.

Do hydroponic plants need special seeds?

No. Hydroponic plants use the same standard seeds you would plant in soil, so there is no such thing as a special hydroponic seed. You start the seeds in a soil-free medium like a germination mat or grow plug, then move them into the system once they sprout.

How long do hydroponic plants take to grow?

It depends on the crop. Fast leafy greens and herbs like lettuce, rocket and basil can be ready to harvest in roughly three to five weeks. Fruiting crops like tomatoes, capsicum and cucumbers take longer, usually a few months from seed to first harvest. Each LaNiTex grow guide lists the expected timeline for that specific plant.

Which plants are hard to grow hydroponically?

Large root crops and tubers like potatoes and carrots are harder to grow hydroponically, because they need room to develop underground. Very large or sprawling plants can be impractical indoors too. Most leafy, herb, salad and fruiting crops, though, are well suited to it.
