Dark Heart Nursery clones are healthy, strong, and vigorous; they should be watered with full strength nutrients (around 1200ppm) starting on day 1. At the nursery we use a custom hyroponic blend which will soon be available to the public as “Pioneer Nutrients.”

A Few Key Points About Watering:

Water thoroughly. It’s important to give your plants a deep watering right after transplanting. This compacts the transplanting media and ensures that there are no large air pockets around the clone. It’s also important to help avoid dry spots within the root ball. After a plant is well-established it’s important to water infrequently but thoroughly so that all parts of the rootball are irrigated and spent salts are washed out.

Water frequently for one week. For the first week after transplanting your clone will not yet have grown a strong root system. It is critical that you make sure that the original rockwool cube remains moist. In some cases, the media surrounding the cube may be wet, but the rockwool will be dry. This is especially true if the cube is exposed to the air. For the first week of growth be sure to closely inspect the original rockwool cube every day and pour about 1 cup of your watering solution on any cube that has dried out.

Look for drainage. When watering, always be sure to water until runoff drains from the bottom of the pot (this does not apply when moistening recently transplanted cubes as described above). This water flushes the media and prevents salt buildup. Up to 20% of the water you give a plant should leave as run off. Inadequate run off leading to salt buildup is a common cause of plant damage.

Keep Your Irrigation Water Cool. Often in a grow-room environment irrigation water is stored in reservoirs or in some other way that causes it to warm up. This can be detrimental as warm water contains less oxygen and is prone to breeding pathogens. For best results try to keep your irrigation water under 70 degrees Fahrenheit.

Pro Tip:

Once the clones are transplanted, water them right away. Fresh transplanting media can wick water away from the cube, drying it out and causing the clone to wilt.
