How to get rid of spider mites during flowering

How to get rid of spider mites during flowering, once and for all!

We’ll walk you through exactly what you need to do to get rid of spider mites during flowering, but the most important thing is that you act FAST.

If this is a familiar sight to you, then you’re no stranger to Spider mites and the havoc they wreck, these nasty little buggers can cover an entire grow overnight, seemingly from nowhere, and if you’re afraid of spiders – a real-life nightmare.

But don’t panic, If acted upon quick enough, you can eliminate them and their eggs and save your crop.

What are spider mites?

Spider mites are typically less than 1mm (0.04 in) in size and often vary in color. They spread rapidly by laying tiny, initially transparent eggs and most species spin silk webbing as a form of predatory protection.

This is where the name spider mites comes from. They are actually part of the Acari (mite) subclass and are not the “Spiders” we know of.

Spider mites thrive in hot and dry conditions, much like a flowering room or tent. Under perfect conditions (around 27c or 80f), the spider mites can hatch in as little as 3 days from being laid and some species can become sexually mature in as little as 5-7 days!

A single female mite can lay up to 30 eggs per day, for approximately 30-60 days until the day they die, that’s around 900 – 1800 eggs per mite, hence the explosive overnight infestation that often occurs.

How to get rid of spider mites during flowering:

So your plants have reached the flowering stage of their life cycle, you have likely invested your time and money to get them where they are today, only to be struck with an infestation seemingly from nowhere.

When your plants are in the flowering stage, the last thing you want to do is use any harmful chemicals, fungicides or insecticides, typically the traditional spider mite removal methods aren’t suitable for the flowering stage as chemicals tend to leave residue and alter the taste of your buds, even more so if applied during the late stage of flowering.

Using CO2 as an effective chemical-free, organic solution:

Whilst CO2 is non-poisonous, you can use it to replace the oxygen in the air, this will deprive the mites of essential oxygen, effectively suffocating them, leaving no residues on your plants or equipment.

This won’t cause any harm for your plants, in fact, a boost of CO2 might help them deal with the stress of damage caused by the mites.

What you’ll need:

  • CO2 Cylinder(s) as well as a Regulator to control the flow
  • Vacuum Cleaner
  • a CO2 Meter to measure the PPM
  • Clean Brushes

How to get rid of spider mites during flowering:

    Make sure that your grow area is sealed as well as you can, tape any cracks in the windows and doors

Any cracks in the doors & windows will allow oxygen in and defeat the objective, so this is essential.

Set your CO2 meter for 12,000 ppm

If you’re using a grow tent, set the ppm to 15,000 – this will allow for any leaks, If your CO2 meter doesn’t go this high, you can use a calculator.

Calculate the amount of CO2 you will need for your grow space, switch off any exhaust fans.

For example, a 1000 cubic feet grow tent will require 12 cubic feet of CO2, use this calculator for an accurate calculation.

Switch your CO2 generator on and leave the room

Uhm, if you don’t leave the room at this stage – you’re gonna suffocate and die… so this is pretty important

After your generator has finished pumping in CO2 turn the exhaust fans on before entering the room.

Let the exhaust fans run for at least an hour before entering the room, otherwise, you run the risk of carbon dioxide poisoning.

You can now enter the room, begin cleaning the webs and dead mites with a vacuum cleaner, you may need to get a clean painters brush and brush upwards to make sure that you get all the webs off your plants.

You will want to repeat this entire process in 5 days to kill any dormant eggs that have now hatched to permanently eliminate the mites.

Spider mites can appear from nowhere practically overnight, luckily we have a chemical free, organic method of getting rid of spider mites during flowering.

How to Get Rid of Red Spider Mites on Cannabis Plants

Inicio » Crop articles » How to Get Rid of Red Spider Mites on Cannabis Plants

How to Get Rid of Red Spider Mites – Red spider mites are one of the most common insect infestations when it comes to growing cannabis. While they may be called spiders, they’re actually mites (Tetranychus Urticae) that spin webs around your plants. This type of mite tends to appear on plants in dry environments, disappearing once the cold arrives. These mites are especially dangerous when growing cannabis indoors.

These annoying pests lay eggs all over your plants’ leaves and it feeds off of their cells. One simple mite doesn’t look like it can do much, but they are incredibly fast at reproducing. A red spider mite infestation can cause irreparable damage to your cannabis plants. They usually start with the weakest plant in the group, causing almost imperceptible damage and moving to the next plant.

If your cannabis plants have become infested with spider mites, you’re going to need to work hard to get rid of them and keep control of your plants. However, outdoors there are other insects that actually feed on mites, and they can be used to keep them at bay while also keeping your plants healthy.

If you don’t keep careful control over the infestation it may never leave your growing area. Make sure to follow any and all indications given by any products used – if you miss any doses or don’t follow instructions, you may end up creating accidental immunity in the mites and you’ll be stuck with them for quite a while.

Preventing Spider Mites

The smart thing to do is to take preventive measures as soon as you can, especially when growing indoors which is where these pests are more likely to set up shop.

We highly recommend using Spider Boom as a natural insecticide during the growth period until your plants begin to flower. You’ll need to dilute 2ml per liter of water, and spray every 10 days. If you’re growing clones, dilute 3ml per liter of water and dip clones for 2 -3 seconds.

This product can also be used in outdoor grows in order to prevent red spider mites.

How to Get Rid of Red Spider Mites

If it’s too late to take any preventive measures and you need to get rid of red spider mites you’ll need to be cautious when it comes to getting rid of them; they reproduce at an amazing rate, especially in warm temperatures. At temperatures over 30°C it can produce an entirely new generation after just a week, whereas at less than 23°C it takes around two weeks. You’ll need to keep this in mind if spraying insecticide.

Spider Boom is one of the best ways to get rid of red spider mites when growing cannabis. It contains extracts from various different types of nettle as well as chia seed, which decreases the mites’ ability to feed and reproduce, which slowly stops the infestation.

Before starting to use insecticide, we recommend using insecticidal soap, which is also known as potassium soap, which is used to remove any possible fungi or bacteria from the plant. Plus, it also helps Spider Boom to stick to the plant for longer. It also helps to soften the exoskeleton of the mites, which allows the insecticide to do its job much faster and fight off the infestation quicker.

As we mentioned before, spraying times will depend on the temperature of your grow room or set up. In order to guarantee maximum efficiency, you’ll need to increase intervals when it’s colder and decrease time between doses when it’s warmer. Here’s a small guide regarding how often you should be spraying depending on the temperature:

  • 23°C: apply every 14 days
  • 24°C: apply every 13 days
  • 25°C: apply every 12 days
  • 26°C: apply every 11 days
  • 27°C: apply every 10 days
  • 28°C: apply every 9 days
  • 29°C: apply every 8 days
  • 30°C: apply every 7 days

When spraying, make sure to also moisten underneath all of the leaves and on top of them; if you see spider webs, make sure to remove them all as the mites sometimes hide in them,

Make sure not to use the same product more than 4 times in a row; mites can actually develop immunity over time. We recommend switching it up if the infestation is persistent.

In order to avoid any nasty flavors or aromas in your flowers, make sure to stop spraying 15 days before harvesting. We recommend spraying during the growth period and until the second flowering week, once the buds start to appear. Once your plant is advanced enough, mites shouldn’t have time to expand enough before harvesting.

If you’re having an issue with mother plants that are in constant veg phase, the best way to deal with infestations is by using a sulfur burner. This will protect your plants from insects and well as fungi.

Other Ways to Get Rid of Red Spider Mites

Like with any other insect, red spider mites also have natural predators, known as Californicus mites. These mites feed on red spider mite eggs and young larva. This might not be as affordable as the other options; it’s definitely the safest and most environmentally-friendly way to get rid of them. Sometimes, if your entire grow has been infected but you want to preserve strains in a mother plant room, all you can do is sacrifice some plants for the greater good of the genetics.

If all of your cannabis plants have been infected with red spider mites but you want to save a mother, sometimes the smartest thing to do is pick your preferred mother plant and take a clone. Remove any remaining mother plants from the room, old pots and anything that was used during the infestation. Disinfect and sterilize everything using anti-fungi and anti-mite products.

Keep in mind how extremely important is to prevent infestations such as these; if you already have one, make sure to use the right products at the right times. If the infestation is too large and you can’t get rid of it, remove any large plants (where most of the insects are), leaving one of each, and repeat the insecticide process.

Learn how to get rid of red spider mites both outdoors and indoors, in the most efficient way possible, as well as preventive measures. ]]>
