What’s the best high pressure hose nozzle for vegetable gardens? It’s actually a “horses for courses”…
Choosing the best lettuce for hydroponics comes down to personal choice in the end. I can tell you my favorite lettuce for hydroponics is Buttercrunch.
I know many will agree with that choice. Romaine is another variety that lends itself to being perfect for hydroponic growing.
In fact, according to a study done by the University of Arizona, the best lettuce for hydroponics is romaine.
The study found that romaine lettuce had the highest yield and was the most disease resistant out of all the lettuces tested. The study also found that romaine lettuce had a higher nutrient content than other lettuces.
I agree with the choice of Romaine as well. But I prefer Butterscotch. As I said, it will come down to personal choice and which you prefer to eat.
Lettuce is a staple in many diets and are perfect to be grown year-round in hydroponic systems.
There are many, many varieties of lettuce, too many to name here and each with their own flavor and texture.
While we have isolated the Buttercrunch and Romaine varieties here as the best lettuce for hydroponics, you need to understand that there are several factors to consider when choosing a lettuce variety for hydroponics.
The three main factors are taste, texture, and nutrient needs. Buttercrunch and Romaine rank high in the taste factor no doubt. They also rate highly in the “texture stakes”. Nutrient need is something you’ll take care of during the growing phase.
This article could easily get out of hand as a guide on how to grow lettuce hydroponically. But let’s not get carried away. It’s about isolating the best lettuce variety to grow hydroponically.
I say Buttercrunch first with Romaine a close second. Personal choice right?
Best Lettuce For Hydroponics: Buttercrunch And Romaine?
So let’s have a closer look at Buttercrunch lettuce and why it’s a good choice for hydroponics. Buttercrunch is a variety of the Butterhead “clan”. It is one of the most popular varieties of lettuce grown today because it combines crispness with tender leaves.
Buttercrunch is a hybridized form of romaine lettuce developed by George Raleigh at Cornell University. He crossed a head of romaine with a butterhead variety.
The resulting plant produces large heads of crisp, dark green leaves that are good for salads. Buttercrunch is hardy and tolerant of heat and drought. It is resistant to downy mildew, mosaic virus, and aphids.
On the other hand, Romaine lettuce gets the vote as the best tasting lettuce. In a salad, you can always taste the Romaine. And it’s a great choice behind Buttercrunch to grow hydroponically too.
One of the main reasons Romaine grows so well hydroponically is its ability to adapt to its environment. Many vegetables, not just lettuce aren’t as adaptable in micro-climates in a hydroponic scenario. Romaine does it with ease.
So when you are wondering what lettuce you should choose to grow in a hydroponics set up, Buttercrunch, a Butterhead variety and Romaine should be close to the top of your list.
Is Hydroponic Lettuce Better Tasting?
Hydroponic lettuce is growing in popularity because it requires less water and produces more food per square foot. But does it really taste better?
There is no clear answer about the difference in flavor between hydroponic and traditional methods of growing lettuce. Some people say there is a slight difference, while others claim there isn’t one.
To be honest, I can never really taste the difference. Admittedly, I’m older now and my taste buds are as good as they used to be.
Meanwhile, the reason why some people think hydroponically-grown lettuce produces better tasting produce is because the plants are closer together, which allows them to receive more sunlight. This makes the leaves look healthier and gives off a sweeter aroma. I’m not sure I buy that.
However, I’ve seen several studies that show hydroponically produced lettuce doesn’t actually taste better.
One study found that the nutrients in hydroponic lettuce aren’t absorbed into the plant like they are in soil. Another study showed that the roots of hydroponic lettuce grow slower than those of soil-grown lettuce.
Soil contains minerals that help keep the root system healthy. These minerals provide the plants with vitamins and other nutrients that allow them to thrive.
In addition, the roots of hydroponically grown lettuce tend to be smaller than those of soil-based lettuce. Smaller roots mean the plant needs fewer nutrients. Soil provides the nutrients needed for growth.
Personally, I don’t think there is much difference. One study I found interesting was published by Research Gate. Click here to read it.
The pH Level Factor
Maybe this is getting a little too scientific but I think understanding the pH levels is important to gardeners wanting to maximize their best chance of producing quality produce.
So what is pH and how is it important to growing lettuce.
The pH scale measures how acidic or basic a substance is. Most plants prefer a neutral environment, with a pH of about 7.0.
However, some plants thrive better in slightly acidic environments, while others do well in alkaline conditions. If you’re growing hydroponic crops indoors, it’s essential to find out what your indoor soil’s ideal pH is.
To determine the ideal pH for your plants, use one of the following methods:
Add a litmus paper or color change indicator strip to the water reservoir.
Use a digital pH meter.
Test your soil pH directly.
What Is pH Levels And Why It’s Important For Growing Lettuce With Hydroponics
Plants require certain minerals to thrive. These include calcium, magnesium, phosphorus, potassium, sodium, sulfur, chlorine, bromine and nitrogen.
Some plants like tomatoes prefer a slightly acidic pH while others like peppers prefer alkaline conditions.
The pH scale measures acidity or alkalinity. Water with a neutral pH is neither acidic nor alkaline. When we talk about pH, it refers to how much hydrogen ions are present in water.
If there are more hydrogen ions, the solution is considered basic; if less, it is called acidic.
In nature, plant roots absorb nutrients dissolved in water which originates from organic and inorganic compounds in the soil and underlying rock.
Without the benefit of the nutrient cycle and interaction that take place within soil, hydroponic growers are altogether responsible for creating the ideal environment that encourages plant roots absorb vital nutrition.
Monitoring and adjusting pH levels is important for hydroponic growing because plants grow better if the pH level is between 5.0 and 7.0.
A plant’s roots will absorb nutrients faster if the soil or water pH level is lower.
Plants grow better if the pH level is between 5.5 and 7.0.
Most gardeners will skip this section. Many will be experienced enough to know their hydroponic set-up’s pH levels or their soil. That’s fine. For “newbies”, it might pay in the long run if you do a little further research on this topic. I guarantee it will make you a better gardener in the long run.
Conclusion: Best Lettuce For Hydroponics
Hydroponic gardening is becoming increasingly popular because it allows you to grow plants indoors without having to use soil.
This method uses nutrient-rich water to nourish the plant roots. There are many different types of hydroponic gardens available today, including vertical farms and hanging planters.
Lettuce works really well in hydroponic gardens. You can harvest lettuce all year round without needing soil! It’s almost an exact science. I would be very surprised to hear anyone “messing up” a lettuce crop using hydroponics.
I’d love to hear your thoughts on things such as taste with lettuce grown hydroponically vs in soil and of course, in your opinion, the best lettuce for hydroponics.
I’m saying Buttercrunch and Romaine. By the way, if you like Buttercrunch, check out some of the other Butterhead varieties and maybe give them a try.
