Planting Instructions


All hemp clones will come ready to plant directly in the field or greenhouse. Plant at 4-6 feet on center with 6-8 feet between rows. If growing in containers, use containers 3 gallons or larger. This ensures proper plant development and maximum CBD or CBG yield. Industrial hemp likes soil with a pH between 6.0-7.0, which is well-drained, and will have 10-14 inches of rainfall (or irrigation) during the growing season.

Raised beds can boost rates of success in more clay-type soils to increase drainage and stave off any water sitting on the roots of the plant. Plastic coverings on these rows can help with weed control, but they make it harder to determine the soil moisture level. Drip Tape can be added as the raised beds are being made to help with controlled irrigation and fertilization requirements.


Do not plant before the last frost date in our area due to the possibility of losing hemp clones to bad weather. There is no reason to rush the planting of the crop as tall plants are harder to harvest and do not increase the CBD or CBG yield of the crop.


Additional Plant Care Tips

Vegetative Stage:

The vegetative stage occurs after the clones have finished rooting and lasts all the way to the flowering stage. During the veg stage, industrial hemp plants are storing up nutrients through absorption in the root system and photosynthesis in their leaves. This store of energy is required for the latter production of flowers. A plant that is unhealthy during its vegetative stage will not produce maximum CBD or CBG amounts in the mature cola.


Flowering Stage:

For cannabinoid producers, the flower is where the money is. The flowering stage is the final phase in the natural reproductive cycle of the plant. Industrial hemp is a photoperiodic plant, which means it will begin the flowering stage as soon as the duration of sunlight declines. Each hemp variety has a small variance to light sensitivity, but a general rule of thumb is that industrial hemp plants begin the flowering stage when day length is less than 12 hours of sunlight.
