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.
Set your  CO2 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.

On September 18th the constitutional court changed its laws around Cannabis in South Africa. In this seismic law shift it is now legal for adults to grow and use Marijuana, locally known as Dagga, in the country. 

So what now?

Well this means that you can legally consume Dagga, however here’s the catch: it is not legal to sell or buy weed, so it is only legal if you grow your own at home for recreational use. The bonus is; you can let your green thumbs go wild, it’s all guilt free growing from here on out.

How do I grow my own Marijuana supply?

Grow Guru* has taken the hard work out of keeping yourself in constant supply of Dagga for recreational use with its easy to use home set up systems. They take the think work out of growing and maintaining a crop, and ensure great yields that will easily keep you in constant supply.
There are two ways to grow Cannabis, outdoor (let nature run its course), or indoor in a hydroponic system (controlled with clear outcomes).

What do I need for a Hydroponics (indoor) system to thrive?

Set-up is relatively simple as Grow Guru has taken the hard work out for you. It is a
matter of assembling the system in a your home, and then maintaining the plant
nutrients with our step-by-step grow guidance.
Plus you can throw a few veggies in there too and fill the kitchen with your harvest.

For a basic set up to get you started: click here or visit our Hydroponics Startup Area

If you are a bit of a hobbyist, and enjoy immersing yourself in a project, you might opt for a more advanced set-up with more grow potential. We have plenty of options to upgrade, improve and enhance your system as you grow, and want to improve your yield. Our advanced range will impress you so take a look at some of the hydroponic components available.

Where do I get seeds from?


You can buy seeds locally or internationally. As the growing of Dagga has been legal overseas for longer, the seed banks are more accurate and the results more predictable.
Attitude Seed Bank is one of the more reliable cannabis seen banks in the world. We recommend you have a browse for yourself.
They are based in the UK and ship to South Africa the next day. Unfortunately once your parcel hits SAPO  the process slows down, and will take around 2-3weeks to get to your nearest Post Office branch. However eventually it will arrive.
We've found the best way to keep track of your parcel is to
visit: http://globaltracktrace.ptc.post/gtt.web/

You can buy dagga / cannabis seeds in South Africa from a number of local cannabis seed banks. Variety seems to be limited at this stage but the beauty of buying local is that you can opt for courier delivery to your door in some cases.

My hydroponic buds are growing, now what?


With Grow Guru’s proven grow systems you can bank on a great yield, so you can start planning for your first harvest. Here are some ways to process your plants, and get enjoying the fruits of your hydroponic system: Harvest

Grow Guru’s got your back


Throughout the process you can be sure we have advice, equipment and nutrients on hand to help you enjoy success with your hydroponic system. We have plenty of
guidance material to help you advance as you grow, and get the most of your system.
The best time to plant is yesterday, the second best time is today. So get those green thumbs to our grow shop and get started.

Grow Guru | Hydroponic by Grow Guru Horticulture (info) - 5M ago

Three part nutrient formulas, have in recent times become some of the most popular hydroponic plant feeding nutrients available, even though these rapid dissolving liquid formulas have been designed and produced with hydroponics in mind, they have seen great results in Coco Peat and soil based mediums as well.

Using 3 part nutrients does have its benefits and drawbacks though, so in this article we will discuss these to ensure that you achieve optimal results from your 3 part liquid nutrients.

Advantages

Three part nutrient concentrates give the grower absolute control over their plants nutrient requirements. With 3 parts to add seperately, experienced growers can fine tune their feeding for every stage of plant development/growth. This is the number one benefit to cultivating plants with 3 part nutrients, and there are a few different formulas to consider when mixing these together for your reservoir or watering.

Disadvantages

The main disadvantage of using a three part feeding program is that the separate solutions will need to be accurately mixed together to achieve the correct ratios required for healthy plant development. If the formulas are added in the incorrect order or ratios, there will be an imbalance within the solution. This will cause nutrient lockout which can lead to the plant showing deficiencies.

How to Mix

Before starting, make sure that your reservoir is clean without any debris or salts present, you don’t want unknown chemicals disrupting your process, affecting your solution.

  • Add clean water to your reservoir first, but remember to measure how much water is going in so that you know how much of each nutrient will need to be added later. The amount of each nutrient added to the mix will depend on plant variety and current stage of growth.
  • These nutrients will need to be added to the water in the correct order. Do not premix together before adding as this will cause nutrient lockout to occur.
  • The first nutrient that will be added to the fresh water is Micro. Grow and Bloom nutrients can be added in any order after Micro, as long as Micro is added first. The Micro will provide Nitrogen, Potassium, Calcium, Zinc, Copper, Molybdenum, Iron, Boron, and Manganese. Be sure to add the correct amount of Micro to the solution for the amount of water used.
  • After adding the Micro, mix the solution and let it stand for a few minutes.
  • The next nutrient to be added will be the Grow. This will provide the plants with Nitrogen, Phosphorus, Potassium, Sulfur and Magnesium. Grow will give plants everything that is needed for healthy vegetative growth and root development. As with Micro, be sure to add the exact dosage for plant variety and stage of growth and mix well. Let the solution stand for a few minutes before adding the Bloom.
  • The last nutrient to be added will be Bloom. This will supply plants with a Nitrogen, Potassium, Phosphorus and Magnesium. Bloom will give plants sufficient nutrients needed for healthy flower and fruit development, this formula is also know to increase the flavour, aroma and essential oil content of flowering plants.
  • Be sure to once again mix the exact dosages and to let the solution stand for a little while before moving on to the next step.
  • The final step will be to test and adjust the pH level of your nutrient solution, this can be measured with a Basic pH Meter and adjusted with plant specific pH Up or Down.
  • Optimal pH levels for hydroponics and Coco will be in the range of pH 5.5 – 6.2, for soil pH 6.2 – 6.8
Mixing Formulas

Most manufacturers supply tried and tested feeding charts with their 3 part liquid nutrients which you can use as a guide. There have been some experienced growers that have created their own formulas and have seen great success doing so. The most popular being the Lucas Formula, this was created by an experienced grower named Lucas and was originally shared through online growing forums, and quickly became one of the most well known formulas using liquid 3 part nutrients, however the Lucas formula uses only the Micro and Bloom concentrations.

Did you know? You can increase your yield by simply supplementing CO2 in your grow tent or grow room!

Some say that increasing the CO2 in your grow environment can increase your yield by 100% or more. While other studies show that CO2 injection into your environment can see a 40% increase. Either way, anything from 30% should make you smile. Growth in veg is prolific and yields in flowering are explosive.

The math is simple: If you would normally achieve 100 units in a grow cycle, you will now get between 130 and 200 units from the same square meterage of grow space. That's a great return!

Indoor gardening with CO2 can be tricky, as too much could kill your plants.

You may ask the question: How to increase your yields with CO2?

We have a range of tools and equipment to monitor, dose and maintain optimum CO2 levels.

Generally speaking, we have about 350-400ppm at sea level here in South Africa. (This increases gradually due to global warming)

Most popular plant varieties can tolerate and make use of CO2 levels from 1200-1500ppm max. This is also determined by the plant variety, strain, genetics and growing conditions. Best advice would be to go easy, monitor CO2 & potential stress. CO2 supplements can be used for plants in hydroponics or soil based grow mediums.

Types of CO2 dosing & enrichment methods:

CO2 Generators

CO2 burners or propane burners

They generate CO2 by burning up oxygen in the environment. These would normally be connected to a controller which would turn the device on and off when required.

TNB Naturals

We'd like to introduce you to TNB Naturals, an all natural CO2 product manufactured in Canada. 

TNB Natural's flagship product "The Enhancer" is a safe & easy to use CO2 product. It generates no heat as apposed to other methods. It's potency makes it a very popular solution for indoor grow tents and gardens as one canister can dose an area of 3.6 x 3.6m. It will produce CO2 for about two weeks, gently tapering off. The Enhancer refill pack is now available and so most growers grab one canister and 2-3 refill packs for their grow. Using The Enhancer is easy! Simply add 1 litre of warm water to the container, shake, peal back the label on the lid and enjoy the benefits.

Additionally, TNB Naturals offers a highly accurate CO2 Monitor for your grow environment which will be available to our customers soon.

We have brought the brand to South Africa and should be available in all leading grow shop nationwide.

If your local grow shop isn't stocking TNB Naturals yet, please ask them to reach out to us and we'll make it happen.

CO2 Canisters, CO2 Regulators & CO2 Controllers

To setup a long term CO2 solution, one would typically need three items.

  1. Canister of CO2 which would be connected to a CO2 Regulator.
  2. CO2 Regulator - Regulators have a built in solenoid valve which allows for accurate control and dosing when turned on and off. The flow rate can also be controlled on the regulator. Ideally you would want to connect your CO2 regulator to a CO2 Controller.
  3. CO2 Controller - CO2 controllers use infrared sensing technology to determine the amount of CO2 in your grow space. You set the required amounts of CO2 on the device initially. The Controller will turn the CO2 regulator on and off as required to achieve your desired CO2 levels. You would want the controller to function during the lights on period. If the controller does not allow for setting or sensing to do so automatically you would need to connect it to a timer or a Gavita Master Controller & ECM Module.

Lastly, 

There's always the home method of yeast and sugar however we don't recommend it as it is not a sustainable solution, attracts pests, stinks, and is not effective comparing to any of the other methods which are available to increase the CO2 in your grow room or grow tent. 

CO2 TIPS:

**IMPORTANT: Be careful of freezing your tank. Too much flow can freeze up your regulator and potentially cause an explosion.

**Increased CO2 allows for increased nutrient uptake.

Maximize your yields this season - Supplement CO2!
