How To Treat Spider Mites During Flowering

Cannabis growers must know how to treat spider mites during flowering using five options. Spider mites are probably one of the most annoying and dreaded pests of growers because they don’t only appear when drying, but they can also happen during flowering. Knowing how to get rid of them during drying and flowering is a skill you should always have with this venture. 

The flowering stage where the buds are starting to form is crucial because you want to have a quality harvest and good yield. However, this stage can also get you to face to face with spider mites. It’s almost impressive how these tiny insects can have such a significant impact on the yield.

Comprehensive Guide On How To Treat Spider Mites During Flowering

 

Option#1. Pruning

The first option you can do to quickly get rid of this problem is pruning the leaves, especially when half of the surface is no longer functional. Once you see the signs such as specks and webbing, it’s best to clip the leaves and vacuum the mites out. During this time, the infestation may not be too severe, yet removing the infected plants and mites can eradicate them. 

You want to repeat pruning and manual removal for several days to ensure that you have removed all the insects. As you are removing and pruning, growers in the greenhouse have the advantage of dropping the temperature to slow the mites’ reproduction rate. This way, you won’t get overwhelmed by their numbers, and eradication will have a higher success rate. 

 

Option #2. Washing

Besides pruning and manual removal of mites, you can hose your plants as well. This is a standard method for eradicating spider mites with other plants, but note that washing does not kill them. If killing the mites is your priority, you can use a mixture of isopropyl alcohol and water. 

Use this solution with a garden sprayer, but be careful not to hit the buds. The mites that will come in contact with this mix will die, and you’ll also be flushing them and the webs off. Target the underside of the leaves as well to get the eggs.  

 

Option #3. Beneficial insects

Did you know that you can introduce predators or beneficial insects to deal with the spider mites? Growers can introduce ladybugs because they can take care of the mites but will not affect your plants. You can also check other insects that will feed on spider mites, including predatory mites and thrips. 

Those growing cannabis indoors can find this method useful because the insects will continue to feed on the spider mites as long as they exist. However, you can expect that the insects will leave if they are outdoors once the spider mite population is gone. More so, this method and the previous ones will only be effective if the infestation is still not heavy, preferably during the initial period. 

 

Option #4. Horticultural oils

The remaining two options for treating spider mites during flowering is the use of essential oils and pesticides. Experienced cannabis growers recommend an array of essential oils for a more natural approach to combating massive spider mite infestation. The horticultural oils that you can use are extracts from plants, including rosemary, eucalyptus, peppermint, and cinnamon, to name a few. 

Think of the oil as to how you’d apply the alcohol and water solution earlier. It’s best to dilute it first with water and apply with a sprayer on the leaves. Much like the solution, mites that will come in contact with the essential oil will die. 

However, do note that you don’t want to spray the buds with these oils. One example is the neem oil with a distinct smell, so be careful not to coat your buds when you’re about to harvest. Otherwise, it’s less likely to save your crops after getting exposed directly to these oils. 

 

Option #5. Pesticides

According to Colorado State University, using pesticides for eradicating spider mites is something that you must practice with great caution. This is because not all pesticides classify themselves as miticides or acaricides that are meant to control spider mites. More so, you risk developing spider mites that are resistant to the chemicals; thus, the control becomes more problematic. 

Be sure to check if the product you use is advisable for your plants, and it’s best to treat insecticides as a last resort. Remember that you are growing something that will be lit and inhaled, so some chemicals are best to avoid. Besides, if you’re at the stage where you’re close to harvest, it will be hard to protect the buds and flush them of these chemicals. 

 

Conclusion

Every cannabis grower can tell you one of the most dreaded pests to have, the spider mites. You can encounter them in various stages, so prepare yourself on how to treat spider mites during flowering. At this stage, you are close to harvesting, so you want to have a good yield amidst the presence of these tiny problems.

You have five options where pruning, washing, and introducing beneficial insects can address low mite populations. On the other hand, you can resort to essential oils and pesticides as your last options if the infestation is too heavy. Just be mindful of the application and choosing a product not to affect the buds.

How To Prevent Root Rot In Hydroponics: 3 Useful Tips

If you’re a newbie gardener who’s looking to find ways to hone your skills, you’d want to learn how to prevent root rot in hydroponics even before this problem affects your plants.

Hydroponics can be advantageous to crops in more ways than one. However, it also comes with risks of diseases, such as root rot, which can be destructive or even lethal to your plants.

Unfortunately, there are no effective methods to recover the wilted parts that were affected by the root rot once it hits your plants. The only thing you can do if you do not want this catastrophe to befall your crops is to prevent it before it happens. Read on to learn more about this subject.

 

What is Root Rot?

Root rot is a disease that attacks the plant roots and causes them to suffer decay. This usually happens when a lack of oxygen supply occurs in the substrate.

To give you an idea, think about plant roots that are submerged in water that only has a little oxygen in it. Over time, the plant suffocates and dies.

Aside from rot and decay, this disease also leads to the proliferation of fungi that are naturally present in the soil. These include Rhizoctonia, Alternaria, Pythium, Botrytis, Fusarium, or Phytophthora. As soon as fungi colonies start to grow, they tend to target the weakened roots and infect your precious plant babies.

Once the plant becomes infected, they won’t be able to take in what they need to grow – water, oxygen, and other nutrients. When this happens, it won’t be long before the plant dies.

 

What is Hydroponics?

In case you’re not aware, the term hydroponic is derived from a Latin word that means “working water”. To put it simply, hydroponics is an art that involves growing various types of plants without soil. If you’re like most people, the first thing that comes to mind when somebody talks about hydroponics would be a picture of plants with roots suspended into the water without using any type of growing medium.

 

Avoiding Root Rot in Hydroponic Systems

Detecting and identifying root rot can be tricky. When your plants get infected, their leaves and roots gradually wither until the whole crop itself dies from the lack of nutrients, which is a common symptom of many diseases.

 

What causes root rot in hydroponics?

One of the requirements in hydroponics systems is oxygen. Without it, your plants are basically on the road to death. On the other hand, lack of such is one of the major triggers for root rot, and it must be avoided at all costs.

Just like when planting in soil, you loosen up the ground so that your plants’ roots can have their required intake of oxygen. That is the case for crops grown in aqueous solutions as well. If they cannot breathe, they would not be able to grow.

Another agent for root rot is the temperature. The last thing you would want in your system are parasites that leech nutrients intended for your plants and infect the water during the process. In common terms, these fungi are called molds.

One of the best breeding grounds for these is warm and moist areas. For this reason, if the water temperature inside your reservoir is high, then you are susceptible to it. Something as minor as letting the solutions exposed to sunlight can already be a risk factor.

 

3 Useful Tips on How to prevent root rot in hydroponics

There is good news! Root rot in hydroponics can be prevented! Just follow these tips:

Tip#1: Use the right air pump

If you do not want root rot to affect your plants, you merely have to avoid its causes. If you need oxygen, keep the water bubbling by providing an air pump of appropriate size, and also give importance to proper ventilation in the room.

 

Tip #2: Maintain the temperature

The temperature should be maintained within the 70 to 80 degrees F range. Get rid of any materials that can make your system vulnerable to infections, and make sure not to disturb your crops while they are trying to grow.

 

Tip #3: Get rid of the rotten parts

However, if you failed in preventing the disease, then the rotten parts should be removed immediately. Cut them off as there is no chance of reviving them, and focus on the potential new growth instead. Fix your hydroponics system and eliminate the risks.

 

Why Give Greenhouse Gardening a Try?

Greenhouse gardening offers numerous benefits to greens aficionados who dare to take their gardening experience to the next level. Aside from acting as a shield against the effects of inclement weather, a mini, hobby, or semi-pro greenhouse can also serve as a protective layer that keeps harmful bugs and critters at bay.

What’s more, its enclosed structure allows you to control your plants’ growing conditions including the temperature, light, moisture, and ventilation of the greenhouse’s internal environment. With a controlled environment, you’ll be able to extend growing seasons and grow plants that aren’t native to your area.

 

Conclusion

No matter how well-informed you are about how to prevent root rot in hydroponics, you cannot completely eradicate the risks. Therefore, to avoid the worst-case scenario, you should be prepared to sacrifice the infected for the sake of others. While you’re at it, consider trying your hand at greenhouse gardening as well.
