Tearing Rockwool In a Indoor Grow Box.

To water or never to water that is 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 genuinely believe that adding more water for their plants in their hydroponic systems may help them grow bigger and better. This notion cannot be farther from the truth as overwatering has killed many a newcomer indoor garden. This informative article explores the correct watering methodology for rockwool in an indoor grow box.

Rockwool is made of molten rock spun into fibers like cotton candy. It provides an excellent substrate for plant roots since it holds at least 18% air constantly and offers the plant root zone with lots of oxygen. However, in addition it possesses a top water holding capacity (WHC) and is definitely an inert medium meaning you will find no biological properties so it’s recyclable. Rockwool is sterile so you may be certain that you will be starting fresh when you germinate your seeds. Seed borne disease like dampening off are nonexistent in rockwool due to 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 broad rule for watering rockwool: less is more. Indoor Grow Boxes Determining how much water depends upon many factors such as for instance plant height and lifecycle stage, light cycle, humidity and the kind 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. Rockwool can be used in all four systems and it’s most reliable in a variety 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 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 whenever your lights first come on in your indoor grow box. The last watering should occur three hours prior to the lights go off. Only water once the lights are on, the plants do not must be watered during their dark or resting phase. So to help keep the cubes moist whenever your plants are below 3 inches you water once for 15 minutes every 2-3 days, ensuring that the rockwool cube feels about “half-way” dry. As soon as your plants are in 6 inches, water 1-2x a day. As soon as your plants are in 9 inches increase watering to 3x each day and once the plants are 12 inches and larger you want to water 15 minute 3-4x a day. Even although plants roots is likely to be embedded in the deep water culture it’s beneficial to still utilize your rockwool cubes for water delivery.

Below are a few other tips to boost success when watering your rockwool in an indoor grow box. Use plastic covers over your rockwool cubes to avoid algae formation. Algae at the the top of rockwool cube can lead to stem rot. If you’d 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 eliminate excess salts and material from the cubes. Conditioning the rockwool is an essential first step and will greatly boost your propagation efforts. The pH of one’s nutrient solution being absorbed by the rockwool must be between 5.5 and 6.0. Stay away from 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 ensure the rockwool is not sitting in standing water as this will 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.
