Providing 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 believe that adding more water for their plants in their hydroponic systems may help them grow bigger and better. This notion can’t be farther from the reality as overwatering has killed many a novice indoor garden. This information explores the correct watering methodology for rockwool in an internal grow box.

Rockwool is manufactured out of molten rock spun into fibers like cotton candy. It offers an excellent substrate for plant roots as it holds at least 18% air all the time and supplies the plant root zone with plenty of oxygen. However, in addition, it possesses a top water holding capacity (WHC) and can be an inert medium meaning there are no biological properties therefore it is recyclable. Rockwool is sterile so you may be certain that you’re starting fresh when 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 an over-all rule for watering rockwool: less is more. Determining just how much water is dependent upon many factors such as plant height and lifecycle stage, light cycle, humidity and the sort of hydroponic technique employed in grow boxes. Gardening Reviews The four most popular of grow box hydroponic techniques are Ebb and Flow, Drip/Top Feed, Deep Water Culture, and Aeroponics. Rockwool can be used in all four systems and it’s most reliable in a mix of technique system. Hydroponic superponics systems that employ the fusion of hydroponic technologies offer the absolute most complete solution for growing plants effectively with rockwool. Combining top feed drip with deep water culture enables an internal grow box owner the ability to automate watering from germination to harvest by timing effective watering cycles down to the minute.

The question then arises: how often do I water my rockwool in my combined deep water culture/ top feed drip system? It’s always best to begin your watering cycle whenever your lights first seriously in your indoor grow box. The past watering should occur three hours ahead of the lights go off. Only water once the lights are on, the plants don’t have to 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, ensuring the rockwool cube feels about “half-way” dry. Whenever your plants are in 6 inches, water 1-2x a day. Whenever your plants are in 9 inches increase watering to 3x a day and once the plants are 12 inches and larger you wish to water 15 minute 3-4x a day. Even although the plants roots will soon be embedded in the deep water culture it’s good for still utilize your rockwool cubes for water delivery.

Below are a few other tips to boost success when watering your rockwool in an internal grow box. Use plastic covers over your rockwool cubes to prevent algae formation. Algae at the top 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 essential first step and will greatly raise your propagation efforts. The pH of your nutrient solution being absorbed by the rockwool should really be between 5.5 and 6.0. Try to avoid drastic changes in the plant’s environment 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 can impact the rockwool’s ability to produce a solid root mass. Finally don’t let the rockwool cubes go bone dry, keep rockwool moist and in consistent temperature, humidity and light intensity and rockwool will reward you with the best tasting end product you’ve ever had.
