To water or to not 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 think 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 facts as overwatering has killed many a newcomer indoor garden. This short 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 offers an excellent substrate for plant roots since it holds at the very least 18% air all the time and supplies the plant root zone with lots of oxygen. However, it also possesses a higher water holding capacity (WHC) and is an inert medium meaning you can find no biological properties so it’s recyclable. Rockwool is sterile so you can be certain that you’re 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 previous listed benefits enable rockwool to consistently typically the most popular hydroponic growing medium in indoor grow boxes.
As a broad rule for watering rockwool: less is more. Gardening Reviews Determining how much water is dependent upon many factors such as for example plant height and lifecycle stage, light cycle, humidity and the sort 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 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 indoor grow box owner the capability 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 as soon as your lights first seriously 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 don’t must be watered in their dark or resting phase. So to 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 are in 6 inches, water 1-2x a day. When your plants are in 9 inches increase watering to 3x each 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 is going to be embedded in the deep water culture it’s advantageous to still utilize your rockwool cubes for water delivery.
Here are some other tips to increase success when watering your rockwool in an indoor grow box. Use plastic covers over your rockwool cubes to stop algae formation. Algae at the the top of 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 the very least 1 hour to eliminate excess salts and material from the cubes. Conditioning the rockwool is an essential first faltering step and will greatly raise 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 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 can impact the rockwool’s ability to produce a solid root mass. Finally don’t allow 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.
