Companion plants

Is there a resource for companion planting in hydroponics that anyone can share with me? I would love to hear ideas about grouping plants together that have similar growth requirements or benefit by being grown together.


Hi @Sassy!

Great topic, thanks!

In general, in Smart Gardens and Wall Farms- all plants should do fine growing side by side, as long as they are planted into the garden in a way that they all get the much-needed light from the lamp.

Some users like to rearrange and move around plant cups while growing- also just to make the overall look more pleasing to the eye. You can do it too if you use normal plant cups. Using pro cups- rearranging plants with roots might be a bit tricky- but still feasible.

So, there are no specific rules for plant groups. Except in Click and Grow 25- it works great with greens in a 5 weeks growing cycle.

If you are a beginner, you may try using one group of plants at a time, e.g. greens and some fast-growing herbs, or flowers.

Happy experimenting! :four_leaf_clover:

@Mirjam, thank you for your reply. I wasn’t thinking so much about aesthetics as I was about grouping plants by similar growth requirements (space, light, height, temperature, air circulation, etc.) and symbiotic relationships (such as which plants help deter pests that other nearby plants may be prone to, or which plants might excrete beneficial substances that enhance the growth of neighboring plants etc.). I read somewhere not to plant peppers and tomatoes together, although I can’t remember the reason for that recommendation. A handy chart of those things would be beneficial to many, I would think. I wonder if the rules of soil companion planting apply to the Click & Grow system? Any thoughts?

Hi @Sassy

That is a great discussion point and now I’m curious about what other users have to say.

I guess the most common way to group plants is by their growth habit e.g. greens, herbs, or fruiting plants, though smart gardens allow growing very different plants at the same time.

Tomatoes and peppers grow well side by side and there is no reason to avoid planting them in the same device. As the plants don’t share root space they will do their own thing, even being planted side by side.

Regarding pests, unfortunately, I have never experienced that any plant would deter any pests in indoor conditions. Companion planting works so well in my outdoor garden, but I guess indoors the pests are soo angry and they destroy whatever they can.

@Mirjam Thank you for your reply. What about growing peppers (especially hot peppers) and tomatoes (and other fruiting plants) side-by-side using the pro plant cups or mesh pots? I’ve read not to do this at least a couple of times on the Facebook Click & Growers page.

Hearing about other users’ experiences regarding companion planting would be most helpful!
