How to deal with spider mites in late flowering stage?
When you are late into flowering the last thing you want to do is use any harmful chemicals or traditional spider mite removal methods in your grow room or tent. While we have found that neem oil
is an effective long term preventative solution, both of these options can leave residue as well as a bad taste on your buds if applied in the late stages of flower development.
Then how do you deal with spider mites successfully, organically & naturally? The answer, Carbon Dioxide (CO2).
As it is organic, and non-poisonous, it is normally considered by growers to be the holy grail of Spider mite control. To top it off, using CO2 to kill spider mites is extremely easy and inexpensive to use.
Why use CO2 to kill spider mites?
While it can be said that
CO2 is non-poisonous, it will kill. It does this by amount of oxygen in the air, as a percentage. This smothers the victim, leaving no lasting residue on your grow equipment or plants, like oil based pesticides and chemicals.
Additionally, your plants will LOVE the
CO2 rich environment.
How to kill spider mites with CO2 directions:
Ensure that your Room is sealed as well as possible. Any leaks will lead to wasted carbon dioxide.
ppm meter to 12,000 ppm, if you have a sealed room. If your meter does not have that large of a range, you can do the math with a calculator
If you do not have a sealed room ie a tent then calculate the CO2 required to 15,000 ppm. This will allow for air leaks in the room.
Switch on your
CO2 generator once you have done your calculations and switch off your exhaust fans.
When the 1 hour is up. Turn exhaust fans on BEFORE entering the grow room. Let these fans run for at least 1/2 hour.
You can now enter the room.
Repeat in 5 days. This should solve your spider mite problem permanently.
A note of advice about how to kill spider mites with
CO2 in flowering:
Please use caution when using
CO2 to kill spider mites. Carbon Dioxide will kill you if you are not careful. It is highly suggested that you have a friend help when doing this project. Make sure that only one person goes into the room at a time, just in case the
CO2 level is higher than expected.
This gas will make you tired and fall asleep. Then you will DIE. If you start to feel tired while using this method you should IMMEDIATELY go OUTSIDE. Breathe the fresh air.
This CO2 eradication method can also be used to cleanse and sanitise the environment before your next load of plants are set to grow and flower.
