Why Grow Your Hemp at NW Transplants?
We are CONTROL FREAKS!
From soil mixing to tray molding, we have control over the entire growing process. Trained staff put eyes on plant material everyday in addition to mechanized controls to maintain growing environment.
How Our System Works
We require 21-28 days of production time. Variables include; day length; temperature; organic vs conventional; and variety.
Seed must arrive by Wednesday at noon to make the seeding schedule for the following week.
Each variety is entered as its own lot number in our system. Each tray is tagged with the lot number, variety name, and outdate (plant date).
Lots under 5000 are put into our PER Tray program; where, we charge per tray regardless of plant recovery rate.
Larger lots are calculated based on a statistical germination rate. Our PER M (thousand), program is billed by plant volume, per one thousand plants.
Pricing is impacted by:
- Outdate – Earlier plant dates, use more energy.
- Program – Organic input costs are 40% higher than conventional.
- Tray size – The more plants we can fit in a tray, the less space it uses.
Delivery is available on lots larger than 5000 total plants. Cost is $7.25/mile one-way.

144 Cell Tray
This tray is commonly used in the vegetable industry for melon and pumpkin. We designed our own 144 tray to increase soil volume and improve root development.
This tray is more forgiving, for growers challenged with timing field readiness and planting date.
Tray is approximately 10″x 20″ and is available in our Organic and Conventional programs.
231 Cell Tray
Ideal for high volume production. Our 231 tray is custom designed to be the highest soil volume 231 in the industry. It is our most popular tray.
Shipping is simplified and price is lower. Conventional and Organic pricing is available.
The 231 is recommended for experienced growers that have mechanized planting. Dimensions are 10″ x 20″ available for Organic and Conventional production.
Vertically Trained Roots
“Why don’t you use a 72 cell tray?”
We are in the business of growing field transplants for commercial agriculture, not container gardening.
Large cell trays may offer greater soil volume, but they produce a weaker root structure.
Roots hit the bottom of the tray and begin to spiral. Once the roots have been “trained” to grow in a circular pattern, it is hard for them to break that in the field.
Often the plug will seek to use all resources within the plug media before it will establish and root into the field.
Flexible, vacuum form trays do not offer the best plug environment for field transplants.
Frequently Asked Questions
Why don’t you use a larger tray?
Bigger is not always better. The 72 cell is a vacuum form tray. The depth of the tray is limited and depth is important when we want to achieve healthy air-pruned roots. In a vacuum form tray, the roots hit the bottom of the container and begin to spiral. Once the roots have been “trained” to grow in a circle, they will struggle to adapt for field performance. The soil capacity is not as important a cell depth to root development and healthy foliage growth.
What is the optimum size for planting success?
5 to 7 inches, depending on variety. As soon as the root structure is developed enough that the plug can pull out of the tray and maintain root mass during planting. Once plants exceed 10 inches in height, we recommend topping the plants and leaving them in greenhouse to recover for an additional week.
How should I care for plants after I receive them?
Unload plants from truck or containers immediately! Store plant in trays until they are ready to go into the field. Set trays in the shade with access to water so that you can keep the soil media moist. Before planting, dip trays in fertilizer and kelp solution to loosen the plug in the tray and ensure the plant does not dry out before irrigating.
How should my field be prepared to ensure transplant success?
Always irrigate the ground before transplanting and water within hours of placing plant in the field. Fine soil texture will aid soil-to-root contact and speed the acclimation of your transplants to the field environment. Proper soil prep and water are the two most important factors to reducing transplant shock.
What genetics do you recommend?
Northwest Transplants is not in the seed and genetics business. We work with seed companies whenever possible to achieve correct germination and growing conditions. We have seen many genetics come through our operation, all have strengths and weaknesses. Be sure to ask your seed source about ideal plant date and number of days to maturity!
