Planting Guide
June 3, 2020
Transplanting
Transplant clones out of plug trays within a few days.
We use a soil-less rooting media for sterility providing an ideal air to water ratio. If you intend to leave your plants in trays for more than a few hours, be sure to water them frequently.
After transplanting, water your plants regularly until established. If you are using drip tape or another automated watering system, ensure water is reaching the plugs.
Soil & Fertilizer
If you are cultivating on land that was previously sprayed with pesticides and herbicides, be aware the soil may be contaminated with growth regulators that have adverse effects on cannabis for years after. If large amounts of your plants display strange growth patterns, this may be the cause. Consult a soil agronomist or horticulture expert for remedies. We strongly urge growers to dispose of these plants as extraction may accumulate high levels of toxins. Most importantly, get your soil tested!
We recommend that no fertilizer be used initially as plants can be burned easily. Soil, water, and plant nutritional tests can help determine what nutrients the plants will need to be provided and what fertilizers will be most appropriate.
Contact your local extension office for soil test and fertilizer recommendations.
Planting Time
For maximum yields, plant outdoors between mid May and early July allowing the plants to grow large before they flower.
Our hemp varieties are photoperiodic, meaning they begin to flower based on hours of daylight received.
Plant Spacing
The space required for a successful hemp crop varies. Factors include planting date, fertility, water irrigation and rainfall and hemp variety characteristics. Most hemp varieties are rapid growing and produce plants that can be over 8 feet tall and up to 8 feet wide. Good airflow and light penetration are important for disease management and good bud formation. Each plant will need full sun.
Most growers will want to lay out their crops with 5 foot centers. This will allow for roughly 1,500 plants per acre.
For more spacing and room to work between the rows, 6 foot centers will allow for roughly 1200 plants per acre.
Healthy Plant Physiological Response
It is normal response in the propagation cycle for the fan shaped leaves to yellow and or die off. It is also possible that the lower leaves may yellow or fall off.
Biomass Yields
When estimating crop biomass, factors such as weather, variety and time of harvest will greatly vary yields. Generally expect 1 - 3 lbs per plant. A list of testing labs for CBD and THC levels can be found here.
