Differences between TDS, EC and PPM – Find Medical Cannabis Website Brampton Canada

TDS, EC, PPM … Do you hear these acronyms but do not know how they differ? Well today's article will interest you Today we will talk about the concentration of nutrients in our nutritional solution (irrigation water with nutrients).

It is essential to determine how many nutrients our plants are receiving.

How is TDS different from EC?

TDS

TDS (Total Dissolved Solids or Total Dissolved Solids) is the amount of salts in a particular solution.

PPM or Parts Per Million is the unit used to measure the TDS. Therefore, the TDS is measured in PPM, in the same way that the weight is measured in grams or kilograms, for example.

If when measuring the TDS and we obtain a figure of 400 ppm, it means that of every million parts of the solution there are 400 that are salts. For example, in a liter of solution we would have 400 milligrams dissolved (since one liter of water equals 1,000,000 milligrams of water).

To measure the TDS what is done is to evaporate a liter of water and weigh what has not evaporated, that is, the salts that were dissolved. One way to carry out this measurement, is by means of a balance that measures milligrams accurately. You also need a flask (glass container) to measure an exact liter and a special oven has the ability to evaporate the solution. Would these be too cumbersome, would not it? Fortunately, there are TDS meters for this.

EC

EC means electrical conductivity. Water to conduct electricity requires dissolved salts, and the more you have, the more the current will flow. If we measure the conductivity we can know how many dissolved salts there are. We obtain this value using an EC meter for Cannabis.

EC is measured in siemens per centimeter (S / cm) or millisiemens per centimeter (mS / cm). However, the meter will convert the conductivity to ppm using a conversion factor (ie, multiplying it by a specific number).

However, the small problem is that for this term to be correct, the value depends on the salts you have. However, since all the nutritional solutions are different, some factors are used that are not very exact, but give an approximate value of the ppm.

The meter measures the siemens per centimeter and transforms it to ppm, which is what appears on the screen.

These values ​​change according to the grower, for example in the US 1 ms / cm will be equivalent to 500 ppm, in Europe 1ms / cm is equivalent to 640 ppm and in Australia 1 ms / cm is equivalent to 700 ppm. It is therefore quite difficult to compare the ppm values ​​between one person and another.

However, there is a solution, if your meter gives you EC and PPM you can calculate the conversion factor:

Conversion factor = ppm / ec

[Es esencial que el EC debe estar en µs y no en ms. Para ello multiplica ms por 1000]
If you know this conversion factor you can share the TDS information so that others can convert it to your measurements.

Keep this: The EC or CE (in mS / cm) is the same in all the meters, so if you want to compare measurements it is better to use these values.

Here’s what you need to know before seeing your regional medical dispensary:You will need a doctor’s recommendation, medical cannabis certificate, and/or whatever proper documentation is required by your condition. Typically, you must be 18 or older to be eligible for a medical authorization, but exceptions could be made in some states for minors with particularly debilitating problems. You will often enroll with a medicinal dispensary. This is to keep your medical cannabis recommendation or certificate on file for regulatory and legal purposes. There’ll be a waiting room. This is to control the flow of patients and product, but a straightforward dividing wall gives patients solitude and direct one-on-one contact using a budtender to discuss medical issues. This procedure can help budtenders and patients track effective medicine in addition to possess a living record of producers and products for future reference and follow up. Medicinal dispensaries usually permit you to smell and analyze the buds before buy. This might vary from state-to-state.

DOES AN APPLICANT NEED MUNICIPAL APPROVAL BEFORE RECEIVING A RETAIL CANNABIS LICENSE? Yes, municipal approval is required prior to the AGLC will subject a retail cannabis license. Applicants should get in touch with their planned municipality to learn requirements concerning municipal retail cannabis laws, zoning requirements, land-use limitations, and location requirements concerning how close a retail store can be into a provincial medical care centre, school, or parcel of land designated as a school book.
Keep non-medical cannabis legal Adults that are 19 decades or older are able to:Have up to 30 gram of authorized dried cannabis or the equivalent in their own person. Share up to 30 gram of legal cannabis with other adults in Canada. Buy cannabis goods from a Yukon Liquor Corporation licensed retailer. Grow up to four crops per family. It is illegal to provide non invasive cannabis to anyone below the age of 19 and for anyone under the age of 19 to have any quantity of anti inflammatory cannabis in Yukon.It is illegal and dangerous to drive while under the influence of cannabis or other intoxicants.
