Pinhole Photography

Pinholes are small openings that allow light to enter a medium. They are formed when atoms or molecules in the material collapse under their own weight.

Pinholes can be created artificially with a camera lens, but they are very common in nature. For example, water droplets form inside clouds and snowflakes appear in the sky. Some animals use them to communicate and hunt prey (e.g., bats). In fact, some insects have special eyes that see through tiny pinholes!

Cucumber With Holes: What Causes Holes In Cucumbers?

In the image above, you can see a cucumber. You will notice that there are two holes in it. These holes were caused by the pinhole camera. There are many different kinds of pinholes in nature. One kind is called “fisheye”. A fisheye pinhole allows light rays to pass through from one side of the hole to another. Another type is called “macro”. A macropinhole lets light rays pass through from one end of the pinhole to another.

How Do Pinholes Cause Holes In Cucumbers?

The reason why cucumbers have holes in them is because they contain tiny seeds which are too big for the pinhole camera. Other objects in the background also get focused when the camera lens is placed on top of them. The lens of the camera focuses the light onto a sensor which records the amount of light entering the camera. When an object passes in front of the light source, it blocks some of the light. By looking at this, we can tell how big or small that object is by looking at how much light it blocks.

How Do I Get A Holes Out Of Cucumbers?

The best thing to do is to put the holes in a dark place where light cannot get into it. If you have a flashlight, shine the light onto the holes. You will find that they begin to close up and will eventually disappear.

How Do You Get Rotten Water Moulds Out Of Cucumbers?

Some people claim that rotten water moulds are invisible creatures that like to live on cucumbers. These invisible creatures do not like to be in the sunlight, so you should go out during the day and leave your cucumbers outside. The sunlight will scare the invisible creatures away!

What Is Eating My Cucumbers?

There are many different kinds of cucumber eaters, but just because something is eating your cucumbers does not mean it is pickleworm. Pickleworm eggs look like tiny hairs (see image). They are laid on the vine. Pickleworm is a white worm that looks like the letter “S”. They like to eat leaves and can grow up to 5 inches (12.5 cms) long. Pickleworm cannot survive in the sunlight, so you should pick them off one by one and throw them away.

What Is A Pickleworm?

The Pickleworm is a type of caterpillar. They are green in color and have brown stripes. They like to eat cucumbers, but they do not burrow into it as many people think. If you see a hole in your cucumber, it probably has some other problem, such as scab or blight. Pickleworms grow up to be the moth of the family.

Cucumbers And Pests

Cucumbers are prone to attack by a number of pests, especially aphids and whiteflies. If you live in a humid place, especially one that is very warm, you might find cucumbers infected with fungi.

There are three major fungal diseases that attack them: scab, anthracnose and downy mildew.

Scab begins as small, brownish spots that appear on the leaves of the vine. They grow and multiply until large parts of the leaves are covered in scabs.

The fruit is also attacked by the fungus, which causes small scabs to form on its skin. When these scabs are knocked off the skin beneath is rotten.

Anthracnose begins as small, black spots on the undersides of cucumber leaves, which then grow and multiply until the leaf is severely affected. The fruit is also attacked, which causes small black spots to appear all over its skin.

When the fruit’s skin is broken, the inside is rotten.

Downy mildew begins as a white, downy mold that grows on the surface of the plant’s leaves. As this spreads, the affected leaves become covered in a fine, white powder and turn yellow before dying.

The fungus can also affect the growing tips of cucumber vines and prevent them from growing. The fruit fails to develop properly and is therefore small and deformed.

The best way to prevent your cucumbers from getting infected by these diseases is to make sure that they are kept free of insects and fungi. If these creatures are detected early, it is easy to remove them before they can infect the cucumber vines or their fruit.

If you do not have the time to maintain a clean garden, you can always hire an expert, such as one from FCS Enterprises, to do it for you.

Harvesting Your Cucumbers

It does not really matter when you harvest your cucumbers, but they are usually ready between 50 and 60 days after planting the seeds. The fruit is usually around 12 inches (30 cms) long and 1 inch (2.5 cms) thick.

You can pick them whenever you want, but make sure that you do not take all of the fruit so that the plant knows it should keep growing more.

If you want to keep the cucumbers for eating, pick them when they are small and less than six inches (15 cms) long. If you want to grow them into larger ones, pick them when they are larger than this.

If you want to store your cucumbers to eat later, wait until they are medium sized and cut them in half lengthwise. Place them in a jar of water like you would celery.

They should last several weeks and still taste fresh when you eat them.

If you can’t bear to give your cucumbers away or eat them all yourself, you can always give them to your friends (and their friends, and their friends…) or sell them to neighbors or even grocery stores.

Selling your excess produce is a great way to make a little bit of money, especially if you have quite a large vegetable garden!


If you live in an apartment, or even a house where you have to share a yard with your neighbors, you might not have the space to grow a vegetable garden. Fortunately, there are alternatives.

City Farms allow people to rent plots and grow their own food. You can also try joining Project EAT, which allows you to exchange excess produce with others in your community.

Gardening takes time and dedication, but the benefits are worth it. You get fresh food, a sense of accomplishment and plenty of memories!


Make sure that you always wash your hands before touching any of the plants in your garden, even if you are sure that they are not infected. Diseases and pests can quickly spread from one plant to another, so it is very important for your own health that you keep them all healthy.

Make sure that you get a soil test done on your garden area before you start planting anything. Your soil might not be good for growing anything at all, and you certainly don’t want to spend your time and money on something that is just not going to work!

Pests and diseases are probably going to attack your garden at some point. It is important that you do not get discouraged and that you keep up the fight.

Make sure you use all the tools at your disposal, like pesticides, natural predators to the pests, etc.

As with any job, make sure that you are clean every time you leave your garden. Otherwise, the pests and diseases will follow you inside and could affect your whole family!

Make sure that you check your plants every single day. If you see a pest, or the signs of one (like spots on the leaves), take care of it immediately.

The longer you wait, the worse it will get and the more work it will be to remedy the problem.

Make sure that you water your plants often. If you are growing your own food, you need to make sure that everything goes as planned.

A dry, hot summer or an unusually cold winter could destroy your garden.

It is important to get your kids involved in the gardening process. Not only will it teach them where their food comes from and how good healthy food can taste, it also helps them develop a sense of accomplishment and pride.

Plus, they can quickly become your little helpers, allowing you to take on more tasks.
