Growing Guides

Step 1: Germination

Using the paper towel method for seed germination, keep the towel moist and place it in a dark environment at 70–80°F. Seeds typically sprout within 1–2 days.

Step 2: Sowing

First, soak the Rapid Rooter in nutrient solution until fully saturated. The pH should be between 5.5–6.5, and the EC should be 0.5 mS/cm (250 ppm). Next, insert the germinated seeds about 0.2 inches deep into the Rapid Rooter. Place the Rapid Rooter into the Planting Basket, then into the Seedling Planting Basket, and insert them into the DWC Hydroponic Bucket. Set the VGrow recipe to “Seedling Mode.” If available, cover the seedlings with a dome to maintain humidity. Ideal conditions: temperature at 77°F; humidity between 70–80%. Seedlings typically emerge within 1–2 days.

Note: At this stage, there is no need to add nutrient solution to the hydroponic bucket.

Step 3: Seedling Stage

Duration: 7–14 days

Temperature: 77°F

Humidity: 70–80%.

Check the moisture level of the Rapid Rooters daily. If they become dry, replenish with nutrient solution (pH 5.5–6.5; EC 0.5 mS/cm).

Step 4: Vegetative Stage

When the plant has developed two sets of true leaves and the roots have penetrated the Rapid Rooter, it is ready to transition to the Vegetative stage. Remove the Seedling Planting Basket from the DWC Hydroponic Bucket and place the Planting Basket back into the DWC Hydroponic Bucket. Prepare the nutrient solution and fill the reservoir with 4 gallons of solution.

This chart is for water starting with a PPM level of zero. For each 50 PPM level of hard water you start with, your EC will rise by 0.1. This is based on the PPM x 500 scale.

Instructions:

It is recommended to use at least the Base Nutrients solution each time you add water, and to adjust the pH to between 5.8 and 6.2.
When using RO water, it is recommended to add a Cal-Mag additive.
If your plant variety requires additional growth weeks, repeat the nutrient concentration from flowering week 8.
This is a baseline recommendation. Please adjust the nutrient solution concentration based on the plant variety, growth conditions, environmental factors, and other variables.
It is recommended to change the nutrient solution once a week.
Please add nutrient solution promptly when the low water alert is triggered.

Maintenance

Prepare the nutrient solution according to the instructions provided with the product.
It is recommended to replace the nutrient solution once a week.
