heath robinson said:The level in the rez is set so that the water level in the bucket is touching or a couple of inches above the bottom of the the inner bucket [or net pot] (the one with the holes drilled in it). The reason for this is I dont like cord roots (the type you see in bubbler bucket grows) to me this is wasting root space.
Here are some pics showing what I mean, these aren't my pics I am only using them to illustrate my point. If you look closely you can see that the roots nearest the bottom of the pot are like cords, this type of root develops when you have a gap between your nutrient level and the pot. I prefer not to have this type of root system as the cords do very little other than support the weight of the roots below.
Here are the roots in a Aquafarm and as you can see they are quite different, this is due to the level being set higher than the pot, and the recirculating nutrient solution. You might notice in the next two pics you can see the water level on the pots. This is the type of root system you should strive for.
I need help, im new to hydroponics and dont really know a solution that works well for hydro. I was wondering does anyone have any suggestions about what nutes to use? If I can get a few different opinions that would be nice.
I dont have a pdf program
