Cucumbers are the crops typically grown thanks to conventional cultivation techniques. Their producing peak is during the summers. The same concerns their growing demand among home gardeners who want to cultivate them instead of buying in grocery shops.
Can Cucumbers Be Grown Hydroponically?
Hydroponic crops are usually grown in nutrient-rich water or a soilless medium like Rockwool. Their cultivation is ongoing in designated hydroponic greenhouses. To achieve the yield of their fruits, you will need to think about allowances for prolific growth in advance. You can buy Hydroponic setups for any liking and preference.
Then, you have to consider whether to cultivate them indoors or outdoors. Growing them outdoors will cater to providing you with more fruits. While indoor cultivation may be ongoing vertically to save space. After that, the consideration should fall for structuring their growth. You can place them in patches, 2-6 feet apart. The bushes and containers, in turn, should be 3-4 feet apart. The preparation of the allowances helps you provide crops with much warmth, moisture and nutrients.

Finally, such crops can be grown hydroponically thanks to maintaining the right temperatures and moisture control. For example, you have to keep a night temperature of about 66 F for having fruits. If it’s lower, the whole growth may be slow for a couple of days. Moisture or humidity should be under control too. If it’s radically low during the winter, crops won’t grow properly.
What Cucumbers to Grow in a DWC Hydroponic System?
When it comes to varieties of crops to grow hydroponically, their genetics mean a lot. To yield the right fruits, you have to understand that greenhouse cucumbers differ from their field counterparts. But, it’s fair to say you can cultivate pretty any type by complying with their growth needs.
Hydroponic cucumbers have varying sizes, shapes, disease resistance characteristics as well as the duration of maturation. First off, special hydroponic types are seedless and have thin skin which doesn’t need you to peel it. Consider such varieties as Lemon, Apple, Lebanese, and Beit Alpha Cucumbers. Secondly, your pick should fall on the variety based on your purposes – whether you plan to have cucumbers or pickles. Thirdly, you can always grow hybrids such as Parthenocarpic. They don’t need pollination but have more hidden difficulties in their cultivation. For instance, you should isolate them from other varieties.
Another categorization of hydroponic crops is the following:
- Burpless – sweet with thin skin and with low amounts of cucurbitacin linked to causing stomach discomfort;
- Bitter-free – even if this variety is left to vine too long, it won’t develop any bitterness found with field counterparts;
- Spineless – a variety without prickly stubs.

How Do You Start a Hydroponic Cucumber?
Now, when you’re done selecting the right variety of cucumbers, learn how to approach the cultivation to have fruits.
How to Trellis Vertically Grown Hydroponic Beans and Cucumbers?
Everything will depend on the right choice of trellis for cultivating hydroponic beans and cucumbers. You can do one alone with DIY instructions found online, or buy it in designated stores. They come in such varieties as A-Frames, arches, chicken wireframes, grids as well as tomato cages. Once done, consider where your crops will grow – determine the proper space, and the approximate amount of fruits you expect to harvest. Then, it’s highly recommended to also consider the ways of further harvesting of crops. It means that you have to efficiently reach crops from any corner of your trellis structure.
When placing the trellis, you have to ensure there’s a balanced support for crops. The vines should be spread generously so that every cucumber has enough space to blossom. Another approach is to grow crops upside down on the trellis.
When the time comes, the vines will climb vertically naturally. Yet, you will need to help them through that journey. Some vines may stay on the ground, so you have to wrap them in the trellis. If they still fall, you have to tie the vines to the trellis with the help of twine, string, wire, zip ties among others. Place the chosen tie under a joint but ensure it won’t be choked on the tie when the stem grows wider. If your fruits are too heavy, you can also put them in fabric slings.

Hydroponic Cucumbers, How Long Till Cucumbers Grow?
There is a different timeline to harvest the hydroponic cucumbers. It all depends on the chosen variety. Most cucumbers are ideal for harvesting when they reach 12-14 inches long. Yet, some varieties which are themselves small vines may be prepared for harvesting when reaching 4-8 inches long. Note, cucumbers on the vine start growing differently. So, you can pick cucumbers from the plant at different times too.
Today, gardeners outline a 50 to 70 days average timeline for harvesting. It’s when crops are sprouted. To understand, it’s high time, fruit should be medium to dark green in colour, and firm. You have to pick it before it starts going yellow. To harvest it, you should snip one approximately a quarter-inch above its vine. Keep in mind, some fruits might turn out to be prickly (if you don’t have a non-prickle variety), so use gloves for your safety. After that, you can remove them upon washing. If needed, take a veggie brush and scrub it properly.
If your goal was to cultivate pickling cucumbers, they are ready for harvesting when reaching 2.9-3.1 length-to diameter size. They should be medium green, a little bit lighter compared to fresh cucumbers. For them, it takes 55 to 65 days from seeding to maturation.
BONUS: What Light Cycle Is Needed for Hydroponic Cucumbers?
Speaking of the light cycle for hydroponic crops, it all leads to the provision of moderate amounts of light only. For instance, 8-10 hours per day is the absolute minimum, while 12-14 hours and 10-12 of darkness is the golden mean. The right light cycle will dictate how many fruits you will have as the result.

Regarding artificial light, its levels of 5500 lux for at least 14 hours daily is pretty adequate. Additional carbon dioxide involvement from 800-1000 ppm will help the crops compensate for low amounts of natural sunlight conditions.
Note, if providing good sunlight to fruits, the plant may allot about 5 square feet of space. More space is perfect with low light in order to avoid overlapping of leaves and shading of the adjacent plants.
BONUS: What PH for Hydroponic Cucumbers?
The optimum pH for hydroponic crops should be between 5.5 and 6.0. It’s much lower when comparing with the cultivation of tomatoes. You have to equip yourself with a designated monitor to record the levels daily and a pH meter alongside indicator paper. To adjust the pH, you have to use an acid or base. Wear special gloves, and goggles, and add acid to the water for balancing the pH levels.
Now, you have a basic understanding of what stays behind hydroponic cucumbers and their demanding cultivation. Do you still think it is too complex for you? Probably not.

Is hydroponics cheaper than soil?
The hydroponic technology of producing crops is getting cheaper and cheaper day by day. Yet, it’s still expensive compared to soil cultivation. For instance, one high-end system can cost you approximately $500 alone.
How long does it take for hydroponic cucumbers to grow?
As per average calculations, a gardener might need 50 to 70 days to grow hydroponic cucumbers.
How many cucumber plants can I grow in a 5-gallon bucket?
Normally, you can grow 2-3 cucumber plants if you take a 5-gallon bucket.
How many cucumbers can you get from one plant?
Again, everything depends on the variety of the plant you cultivate. Taking into consideration average calculations, one plant may yield around 10 fruits. If a plant gets proper watering control, the number may be greater. If a plant produces less than 5 fruits, you’re most likely to violate the growing requirements.
How do you increase the yield of a cucumber?
It can be achieved by proper maintenance of the plants. For instance, you have to ensure cucumbers get enough watering to thrive. The more water they get, the more fruit they produce. Consider giving the plant at least 1 gallon of water per week. It especially concerns the period when the first flowers appear.
Should you pinch off cucumber flowers?
It all depends on the variety of cucumbers you plant. Some bush varieties will need some kind of pruning when they are getting too close to the nearby plants. The first flowers to appear on the plant are the male ones and after only - female ones. The male ones will fall off alone.
What fertilizer is best for cucumbers?
Normally, cucumbers don’t have much nitrogen requirements for growing; however, they need high levels of phosphorus and potassium. To help cucumber plants grow faster and yield fruits, you will need certain fertilizer formulas with those two chemicals. Yet, you have to also be careful not to overfeed the plant. So, go for formulas with packages that read 20-20-20 or 30-30-30.
Is Epsom salt good for cucumbers?
Epsom salt is known as Magnesium Sulfate. When the soil where you cultivate cucumbers lacks both Magnesium and Sulfur, the plant can be affected in growth. So, when you apply Epsom salt, your plant is more likely to give more yields and soil to produce greener vines. In simple terms, this salt just gives an extra boost to the cucumber plant and rejuvenates it.
