Applying water Rockwool In a Indoor Grow Box.

To water or not to water that is the question. Every indoor grow box owner has asked themselves if they’re under watering or higher watering their rockwool cubes. Many novice indoor grow box growers think that adding more water with their plants in their hydroponic systems may help them grow bigger and better. This notion can’t be farther from the truth as overwatering has killed many a newcomer indoor garden. This short article explores the appropriate watering methodology for rockwool in an indoor grow box.

Rockwool is manufactured out of molten rock spun into fibers like cotton candy. It offers an excellent substrate for plant roots since it holds at least 18% air constantly and provides the plant root zone with plenty of oxygen. However, it also possesses a top water holding capacity (WHC) and is definitely an inert medium meaning you will find no biological properties therefore it is recyclable. Rockwool is sterile so you can be certain that you’re starting fresh whenever you germinate your seeds. Seed borne disease like dampening off are nonexistent in rockwool due to the sterility of the medium. All the previous listed benefits enable rockwool to consistently the most used hydroponic growing medium in indoor grow boxes.

As an over-all rule for watering rockwool: less is more. Determining simply how much water depends upon many factors such as for instance plant height and lifecycle stage, light cycle, humidity and the sort of hydroponic technique employed in grow boxes. The four hottest of grow box hydroponic techniques are Ebb and Flow, Drip/Top Feed, Deep Water Culture, and Aeroponics. Gardening Reviews Rockwool may be used in all four systems and it’s most reliable in a combination of technique system. Hydroponic superponics systems that employ the fusion of hydroponic technologies offer probably the most complete solution for growing plants effectively with rockwool. Combining top feed drip with deep water culture enables an indoor grow box owner the ability to automate watering from germination to harvest by timing effective watering cycles down seriously to the minute.

The question then arises: how often do I water my rockwool in my own combined deep water culture/ top feed drip system? It’s always best to start your watering cycle as soon as your lights first come on in your indoor grow box. The past watering should occur three hours before the lights go off. Only water when the lights are on, the plants don’t must be watered in their dark or resting phase. So to help keep the cubes moist as soon as your plants are below 3 inches you water once for 15 minutes every 2-3 days, making sure that the rockwool cube feels about “half-way” dry. When your plants have reached 6 inches, water 1-2x a day. When your plants have reached 9 inches increase watering to 3x a day and when the plants are 12 inches and larger you wish to water 15 minute 3-4x a day. Even although plants roots will soon be embedded in the deep water culture it’s beneficial to still utilize your rockwool cubes for water delivery.

Here are some other tips to boost success when watering your rockwool in an indoor grow box. Use plastic covers over your rockwool cubes to prevent algae formation. Algae at the the surface of the rockwool cube can cause stem rot. If you would like more active plants water less as overwatering will inhibit root production. Always soak or “condition” your raw rockwool cubes in plain water with pH of 5.5 for at least 1 hour to remove excess salts and material from the cubes. Conditioning the rockwool is an important first faltering step and will greatly raise your propagation efforts. The pH of your nutrient solution being absorbed by the rockwool should be between 5.5 and 6.0. Stay away from drastic changes in the plant’s environment such as a huge pH fluctuation or adding a lot of nutrient solution. Rockwool drains well, but make certain the rockwool is not sitting in standing water as this may impact the rockwool’s ability to generate a solid root mass. Finally don’t allow rockwool cubes go bone dry, keep rockwool moist and in consistent temperature, humidity and light intensity and rockwool will reward you with the very best tasting end product you’ve ever had.
