Blueberry DWC

So... This is my first attempt at a DWC grow. Set the DWC kit up and placed the rock-wool into the net and covered with clay pebbles Water is around 14l (Buckets are 19l) This has it bubbling just over the 1st layer of clay and onto the Rock-wool. 15th March - I'll update this diary every Monday and Thursday Light is at 25% power, 25cm from the plant. 18hrs on. Extraction fan set to keep humidity at 75% I have a humidifier running on its lowest setting. This will be removed when the plant is a little bigger 16th March - Gave it a light top watering. This is because until roots grow fully into the liquid I want to make sure it has some H20 to drink 18th March, Thursday - Roots coming through net cup
