To water or not to water that’s the question. Every indoor grow box owner has asked themselves if they are under watering or higher watering their rockwool cubes. Many novice indoor grow box growers believe adding more water for their plants within their hydroponic systems can help them grow bigger and better. This notion can not be farther from the facts as overwatering has killed many a novice indoor garden. This information explores the appropriate watering methodology for rockwool in an inside grow box.
Rockwool is made of molten rock spun into fibers like cotton candy. It offers an excellent substrate for plant roots as it holds at the least 18% air at all times and offers the plant root zone with lots of oxygen. However, additionally, it possesses a higher water holding capacity (WHC) and is definitely an inert medium meaning there are no biological properties so it’s recyclable. Rockwool is sterile so you may be certain that you will be starting fresh once you germinate your seeds. Seed borne disease like dampening off are nonexistent in rockwool because of the sterility of the medium. All the last listed benefits enable rockwool to consistently the most popular hydroponic growing medium in indoor grow boxes.
As a general rule for watering rockwool: less is more. Determining how much water depends upon many factors such as plant height and lifecycle stage, light cycle, Indoor Grow Systems humidity and the kind of hydroponic technique employed in grow boxes. The four most popular of grow box hydroponic techniques are Ebb and Flow, Drip/Top Feed, Deep Water Culture, and Aeroponics. Rockwool can be utilized 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 the most complete solution for growing plants effectively with rockwool. Combining top feed drip with deep water culture enables an inside grow box owner the capacity to automate watering from germination to harvest by timing effective watering cycles right down to the minute.
The question then arises: how often do I water my rockwool within my combined deep water culture/ top feed drip system? It’s always best to start your watering cycle whenever your lights first think about it in your indoor grow box. The last watering should occur three hours prior to the lights go off. Only water when the lights are on, the plants don’t must be watered during their dark or resting phase. So to keep the cubes moist whenever 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 are at 6 inches, water 1-2x a day. When your plants are at 9 inches increase watering to 3x each day and when the plants are 12 inches and larger you intend to water 15 minute 3-4x a day. Even although the plants roots is likely to be embedded in the deep water culture it’s good for still utilize your rockwool cubes for water delivery.
Here are some other tips to boost success when watering your rockwool in an inside grow box. Use plastic covers over your rockwool cubes to avoid algae formation. Algae at the the top of rockwool cube can cause stem rot. If you want 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 the least 1 hour to get rid of excess salts and material from the cubes. Conditioning the rockwool is a significant first step and will greatly increase your propagation efforts. The pH of one’s nutrient solution being absorbed by the rockwool ought to be between 5.5 and 6.0. Try to avoid drastic changes in the plant’s environment just like a huge pH fluctuation or adding an excessive amount of nutrient solution. Rockwool drains well, but make certain the rockwool isn’t sitting in standing water as this will impact the rockwool’s ability to make 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.
