I thought I’d throw up some pictures of the ebb and flow system for those who are interested.
Here’s the drum and controller. There are three 1/4 inch hoses for the three large air stones running all the time. There’s also a pump inside the drum which supplies the nutrients into the controller bucket which gravity feeds all the other pots. You can see I have the timer set for 1/2 hour five times a day. I see that when setting the timer yesterday I have one set at 15 mins. I’ll get that tomorrow morning.
There’s a pump inside the controller bucket to pump the nutrients back into the drum after the 1/2 hour.
This is how the nutrients feed and drain into the pots. This is where you develop a problem with roots forming down into the elbow restricting the flow.
Here’s my Gold Leaf clone which is looking great.
