WATERING

What To Know 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.


Helpful 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.
