frequently asked questions: Growing
what do i do with my products packaging waste
how do i mix my uBuntu Cannabis nutrients
Depending on your plants growth stage, each part must be mixed grams per 10lt of water.
how often do i feed/ water my plants
your plants will quickly indicate if they need water.
can i use tap water with uBuntu Cannabis nutrients
you can use tap water, but its best to use reverse osmosis water / dechlorinated tap water / spring water / rain water
can i use my uGrow kit with uBuntu Cannabis hydroponic nutrients outdoors
hydroponics has a myth attached that it can only be used indoors. you can grow with hydroponic nutrients outdoors but must be aware of the following:
environmental conditions like heat and wind can dry your grow medium out quicker, so be sure to mulch
Environmental conditions like rain can dilute your feed mix in the root zone, but all you have to do to correct this is to feed your plant uBuntu cannabis nutrients after the rain has passed
do i need an EC and pH meter?
it is advisable to use a pH and EC meter to meaure EC and pH but our nutes are rather forgiving and adjust most water to the correct range. Remember the ideal pH for hydro growing is 5.5 to 6.5.
do i need a grow light to grow Cannabis
Only if you are growing indoors. If so, please see our range of LED lights in our shop.
do i need to conceal my Cannabis plant in a tent or closet?
only if you have something to hide. the Concourt Judge ruled that adults in South Africa have a constitutional right to cultivate and consume Cannabis in private, so if you have nothing to hide, grow your ladies off within your home / private space without the need to hide them away.
do i get a free seed with my uGrow kit
Yes, you recive a free seed. we gift you one feminized seed to grow in your kit. we stronly recommend you watch our Speakeasy Potcast episode 1 to verse yourself with the benefits of CBD (cannabidol) in the recreational space. this knowledge and having a CBD plant ready to consume could help you and end the terrible feeling of consuming too much THC.
How big a sample do I need?
Your sample should be a flower no less than roughly 150-200 mg. As the technology is non-destructive, you can analyze your fully intact bud with complete confidence. Bliss testing also offers the option to analyze ground flowers / trim and oil extracts (again, a 150-200 mg sample is required).
What products can we analyze
Bliss testing can measure a full intact bud, ground flowers / trim, and cannabis extract (RSO)
How does this form of testing compare to a lab
Our results are within ±10 % of the HPLC (High Performance Liquid Chromatography) reading. Our reference database contains detailed readings from thousands of flowers that have been analyzed using HPLC in the ISO 17025 lab in Israel, as well as other leading labs in Europe and the US. Repeatability also stands at ±10%.
What if i still have questions
No problem! Reach out to our support team at firstname.lastname@example.org and a representative will provide you with all the answers you need.
What technology do we use?
Which cannabinoids do we report?
The reports total THC and total CBD, which are calculated from 4 different cannabinoids. (Total THC = 0.877 x THCA + THC. Total CBD = 0.877 x CBDA + CBD.)
Note that the technology results are percentages of total weight whereas HPLC results are percentages of dry weight.
GemmaCert repeatability for:
• Ground is up to 0.6%
• Flower is up to 1.5%
Therefore, if you are eager to find accurately the composition of a particular flower, we recommend averaging results across several analyses.
How long does it take to analyse a sample
It takes just 3-4 minutes to run each sample.
What if i want my sample back?
No problem, the analysis does not harm your flower, the cannabinoids or terpenes. You are more than welcome to take your sample back, just arrange a courier to collect and return.
Protocol for Wet (Fresh) Flower Potency Testing
By: Dr. Raya Liberman-Aloni
Sending samples to an external lab is costly and can take a few days before you get results. By then, your crop’s THC levels are higher.
The technologies Protocol for Wet (Fresh) Flower Potency Testing is a practical solution for analyzing crop potency within 24 hours at a fraction of the cost of an external lab.
If you are medical or recreational cannabis grower, then you may also seek to time your harvest just right to achieve a desired potency level. The same protocol below will also be useful for you.
Wet (Fresh) Flower Protocol for Potency Testing
This protocol is recommended for using the technology to estimate Total THC and Total CBD levels in wet flower in the weeks prior to harvest to assist in scheduling the optimal harvest date. *
First, we urge you not to dry flowers under direct sunshine or by using a microwave/oven.
The optimal drying process should be gradual and extended over a 24-hour period.
A whole plant dries within 24 hours to reach about 15% moisture when spread evenly to a depth of approximately 6 inches (15 cm) at 105˚F (40˚C). If hung to dry, in 36 hours at 86˚F (30˚C), 15% moisture is achieved. Fresh flowers, stored in paper bags at 70˚F (21˚C) and 40% humidity, will reach about 11% moisture in 5 days.
Therefore, we recommend a semi-air-drying protocol for reliable and quick results:
1. Flower buds should be cut into a few chunks (not shredded) and placed or wrapped in a paper bag.
2. Then place the paper bag in a relatively warm place with a temperature of about 86˚F
(about 30˚C). If an incubator is unavailable, then just place it next to a heater on low temperature or even on top of an appliance like a TV.
3. The buds should be dry in 24 hours and ready for potency analysis
Make sure that you are not exposing the flowers during the drying process to temperatures which exceed 150F° degrees (65°C) as it may cause the decarboxylation of cannabinoid acids and lead to an inaccurate measurement. Also, the humidity of the surrounding area should not exceed 50% as it may harm the drying process.
* This protocol does not replace a proper curing process and testing of the final dry product.
Does the technology analyse by Non-Destructive Means?
Yes, the technology is the only device on the market which can analyse cannabis by 100% Non-Destructive Means. There is no need for samples be homogenized via grinding to reduce potential measurement errors.
What are the minimum and maximum detection thresholds?
Minimum detection threshold 0.2% (THC, CBD) for Essential and Pro and 1.0% (THC, CBD) for Lite.
Maximum detection threshold 30% THC, 20% CBD.
How does NIR Spectroscopy compare to HPLC?
Both analytical methods provide results based on estimation. The HPLC does so by using chemical reference standards. NIR spectroscopy applies a reference database.
Variance between HPLC results is also common. Results are subject to the analytical method applied, device calibration, sample preparation, operator skills and results interpretation. Consequently, HPLC performance is exposed to human error.
