Few things go together better than hydroponics and greenhouses. But just because two things mesh well doesn’t mean things can’t ever go wrong! Preventing risks to your greenhouse, growing setup, or production-based business is called for no matter what (or how) you grow. With hydroponics, some of the risks may surprise you.
But even when you grow hydroponically— a production method famous for convenience, cleanliness, and more-or-less easy growing— you still need to look out for the little details that can make everything go wrong, and that goes for greenhouse growing too. Here are 8 of these risks to be aware of and reduce while growing hydroponics in a greenhouse. These are common and apply to almost every hydroponics or greenhouse situation— look out for them!

Fire hazards
How could a water-based system pose a fire hazard? It may seem counter-intuitive, but professional hydroponic growers know all about this risk. Hydroponics (and especially in greenhouses, no less) require tons of electrical hookups, lighting, and other appliances. If not installed, wired, or run correctly, any one of these (or all) could bring the whole thing down in a blaze if you’re not careful.
Some quick tips for avoiding this nightmare scenario: if you can, have everything installed by a certified electrician. Even if it seems convenient in the moment, avoid using extension cords as much as possible (be sure to check out manufacturer guidelines for proper hookup). Use surge protectors around your structure which can help prevent short circuiting or overloading. Keep flammable things like media, row covers, plastic, etc. away from heaters, outlets, cables, or appliances.
Food safety hazards
Plants love water. This is just one part of what makes hydroponics so amazing. However, there’s just one unfortunate detail you shouldn’t forget though: pathogens absolutely love water, too.
It’s tempting to think of hydroponics in a greenhouse as a way “safer” setup because it uses no dirt or soil. This couldn’t be further from the truth. If you don’t keep your hydroponics system well cleaned, sanitized, and maintained, pathogens like bacteria and even viruses can enter and get on your plants. If these get on your plants and aren’t washed off or cleaned during the harvesting and packing process, it’s not just a threat to the health of your customers. There could also be some liability issues waiting for you, too, thus making it a threat to your business overall.
Plant disease hazards

Diseases that get from plant to human are only one set to worry about. Other pathogens of bacterial, fungal, and viral nature love areas with water and moisture, and can directly affect your crops, too— making them sick, impact their sell-ability, or even cause complete crop loss.
While hydroponics has tons of advantages, spreading of disease is certainly a risk with the system and it should be considered and prevented. Compared to soil or other hard media, once a pathogen dangerous to plants enters the system, it doesn’t just make one of them sick, low quality, or possibly die— it can actually affect all of them. Any contamination in the water will carry the disease directly to all of your plants. More reason to check on, clean, and sanitize systems regularly.
Power outage hazards
Another risk to hydroponics and greenhouse growing: your plants are all dependent on the grid. Unlike outdoor growing where sunshine and air movement are a given— giving plants their photosynthesis and disease reduction needs— if there is even a short-term power outage, this means your plants will lose light, air flow, humidity controls, temperature controls, and nutrients during that time. This can be devastating to any degree.
No matter what you do to prevent risk, power outages can and do happen to even the most fastidious and cautious of growers. You can prevent this potentially by putting your hydroponics or greenhouse system on a completely different circuit (such as off the grid with hydroelectric, wind, or solar) or you can be vigilant and have a backup generator handy to get your plants through power outages of any length of time.
Freezing hazards
If heating components are humming along perfectly in your greenhouse (and you regularly check that they do), then you really don’t need to worry about your hydroponics system. That said, it’s not the worst thing in the world to check on these and your hydroponics system often, especially during freezing weather.
Obviously a freeze even in one area of the system could jam up and affect the entire growing operation. Not to mention: cold water running at the roots of some of your plants may be less than ideal, even if there isn’t freezing happening there necessarily.

Preventing cold and freezing hazards in your hydroponics in a greenhouse requires a full-scale check. And just of your hydroponics and heating appliances, but also of your entire greenhouse. Things like cold leaks and drafts in especially cold regions could lead to unsuspecting freezes— and it’s much better to check than to deal with the fallout.
Lack of oversight
In some ways hydroponics makes growing in a greenhouse a smooth experience. One tradeoff however is that they need to be monitored and checked almost constantly: either by the operator themselves, or at the very least a paid employee.
You might be able to walk away from something like a small vegetable garden or farm, but you really can’t walk away from a hydroponic system! Even the smallest lapse or error in hydroponics that doesn’t get immediately fine-tuned can threaten the entire operation. To prevent this, make sure you are always checking your system (or have a means to at a distance, such as with an app or smart greenhouse technology); or, make sure you have employees that are highly trained to be attentive and watchful to even the most minute detail of your hydroponic greenhouse system.
Don’t let the idea of risks to your growing operation get you down. All growing operations, even hydroponics in a greenhouse, have some level of risks.
Even very advanced growers face risks they cannot control. For both amateur and senior growers, however, one of the most comprehensive ways to financially protect any greenhouse business from the widest range of risks is through greenhouse insurance.
