Outdoors this strain does well with stressful issues such as bad weather and insect infestations, although you should still definitely take preventive measures. It’s rot-resistant, so if you live somewhere humid and cold you shouldn’t have any issues. You’ll need to wait until mid-October in order to harvest this beauty; just one of these plants can yield up to 1kg.
Toxic – Sativa Hybrid Cannabis
Toxic by Ripper Seeds is a strain that tends to grow quite tall, although if you manage to keep it under control you can grow long, thick colas of buds full of resin and intense physical and mental effects; highly recommended.
When grown indoors, we recommend growing using a SCRoG system; this allows you to easily control how tall these plants grow and create larger colas. We highly recommend this strain because we know that it will not disappoint in as far as yield, but make sure to follow SCRoG instructions strictly. After 65-70 flowering days you can harvest up to 500g per square meter under a 600w light when done perfectly.
Toxic by Ripper Seeds is a 60% sativa strain that comes from a Ripper Haze x Criminal+ combination. This strain gives potent effects as well as large yields, and this plant does well with almost every climate.
1. Microwave extraction. Hemp seeds (1 g) were macerated in a mortar using a pestle, reweighed and then transferred into a vial, and suspended in ethanol (10 mL). The vial was sealed and the suspension was heated in a microwave to 150°C with stirring at 900 rpm for 20 min. The suspension was allowed to cool to room temperature and filtered on a pad of Celite ® (2 g) and activated carbon (0.25 g). Solids were washed with additional solvent, and all fractions were concentrated to dryness under reduced pressure at 25°C to obtain a sticky resin (yield: 27–38%).
In an earlier study, Ross et al. conducted an investigation to determine Δ 9 -THC content in drug- and fiber-type (hemp) cannabis seeds. 7 Hemp seeds in this study were found to contain 0–12 μg Δ 9 -THC per 1 g of seeds, but Δ 9 -THC in drug-type cannabis seeds was in much higher levels (35.6–124 μg/g). It was found that majority of Δ 9 -THC was located on the surface of the seeds, and a wash with chloroform removed upto 90% of Δ 9 -THC. It was suggested that fluctuations in the Δ 9 -THC content of different replicates of the same type of seeds could be the result of the degree of contamination on the outside of the seeds. In this study of consumer-grade hemp seeds acquired from the grocery stores, highly variable, but above the legal limit of, Δ 9 -THC may suggest either contamination by drug-type cannabis seeds or improper washing of the seeds.
The other major phytocannabinoid in hemp, CBD, is an antagonist of CB1 and CB2 with relatively weak binding affinities. 12 While CBD is not known to exhibit psychoactive properties, CBD can be cyclized into Δ 9 -THC when incubated with artificial gastric juice at 37°C. 25 Given that CBD was present in generally higher amounts than Δ 9 -THC, the conversion of CBD into Δ 9 -THC in the stomach after consumption may further contribute to the psychoactivity of hemp seeds.

4. Supercritical fluid extraction (SFE). Hemp seeds (1 or 2 g) were macerated with a mortar and pestle, reweighed, and transferred to an extraction vessel. The extraction was performed using supercritical CO2 as solvent A and ethanol as solvent B. The photodiode array detector was used to monitor the extract, with the range set to 200–600 nm. The back-pressure regulator was set to 12 MPa for the SFE, and other conditions include the following: flow rate=10 mL/min for both CO2 and slave pumps, and 1 mL/min for the make-up pump; temperature=40°C; and gradient: 0–25 min: solvent A, 100%→50%, and solvent B, 0%→50%; 25–26 min: solvent B, 100%; and 26–30 min: solvent A, 100%. The acquisition time was 30 min and the total run time was 30.2 min. All fractions were combined and concentrated to dryness under reduced pressure at 25°C to obtain the extract as a resin (yield: 31–37%).
Discussion: We discovered that Δ 9 -THC concentrations in these hemp seeds could be as high as 1250% of the legal limit, and the amount of phytocannabinoids depended on the extraction procedure employed, Soxhlet extraction being the most efficient across all three brands of seeds. Δ 9 -THC and CBD exhibited significant variations in their estimated concentrations even from the same brand, reflecting the inhomogeneous nature of seeds and variability due to the extraction method, but almost in all cases, Δ 9 -THC concentrations were higher than the legal limit. These quantities of total Δ 9 -THC may reach as high as 3.8 mg per gram of hemp seeds, if one were consuming a 30-g daily recommended amount of hemp seeds, and is a cause for concern for potential toxicity. It is not clear if these high quantities of Δ 9 -THC are due to contamination of the seeds, or any other reason.
Extraction methods employed in this investigation utilize somewhat different principles to extract the phytocannabinoids from the hemp seeds into the solvent. Microwave-based extraction method used ethanol as the solvent, but at temperatures up to 150°C with stirring; majority of the acid forms, Δ 9 -THCA and CBDA, would be converted into the corresponding neutral forms, Δ 9 -THC and CBD, due to exposure to high temperature. This extraction process is also expected to offer high solubility to the phytocannabinoids due to heating to higher temperatures. Sonication was conducted at an ambient temperature using ethanol as the solvent, and is expected to help release compounds from the plant materials. SFE was conducted using a mixture of supercritical CO2 and ethanol as solvent, at high pressures, but temperature was maintained at 40°C; thus, the extraction efficiency depended on the solubility of phytocannabinoids in supercritical CO2 and ethanol mixture. Most exhaustive extraction, due to high temperature and long extraction time, is likely to be Soxhlet extraction, which was performed at the reflux temperatures in ethanol and for up to 4 h. Among these four methods, one would anticipate the highest yield of phytocannabinoids from Soxhlet extraction. Since ethanol was used in all these extraction methods, differences in extracted quantities of phytocannabinoids can be attributed to the extraction methods themselves.
As for claims that hemp seeds can help with losing weight or improving cardiovascular health, Lagano cautions that seeds, on their own, will not solve health issues. To lose weight, she says, the seeds need to be “part of an appropriate food plan.”
The council’s view is that it is better to consume seeds derived from hemp as these crops have been optimized for food production.
Munching on these crunchy bits could be a new health trend, but before cracking open a pricey bag, consider if pot or hemp seeds are the best choice for you and what you’re hoping to achieve.
Seeds produced from hemp have been bred for specific purposes, including food or oil while cannabis seeds that consumers buy online for growing have been bred for cultivating drug-type marijuana plants, the Cannabis Council of Canada states. Marijuana seeds can be substituted for hemp seeds, but the council recommends eating hemp seeds because there is little information on the nutritional value of marijuana seeds.

Hemp seeds are sold in Canada for consumption and come at a much lower cost. For example, a 454-g bag of Hemp Hearts is $13.49 (free shipping on orders over $35) on Amazon.ca.
Two tablespoons of hemp seeds contain about two g of fibre, five g of protein and 300 mg of potassium, Keri Glassman, a registered dietitian and author of the The O2 Diet: The Cutting Edge, Antioxidant-Based Program That Will Make You Healthy, Thin and Beautiful, notes in a WebMD article. The fatty acids, along with gamma linoleic and stearidonic acids, can fight inflammation, help keep the heart healthy and improve the immune system, Glassman contends.
