water level
so i am going to start my very first hydroponics garden very soon. i bought a few black pails (12L/3gal) with lids and 5" net pots. i will be doing a bubbler system. what im wondering is how high the water level needs to be in the pail. does the net pot with hydroton need to be submerged in the water? or does the water level need to be below the net pot?

Although if you are planing an system where the plants roots are submerged continuously, and adding the air bubbles to the nutrient solution so the roots get enough oxygen/air. It would be best if you could design it so the water level is adjustable, so you can test it at different heights. But a basic rule of thumb is that you want the water level high enough to submerge all the roots but not so high that the plants develop stem rot. Probably somewhere between 1 and 3 inches depending on the plants you are growing. My pepper plants seemed to do fine with the water level about 2 inches below the growing medium. My strawberry's were more tricky because they don't have a single stem but rather a bunch of stems coming out of a ball, but I tried to keep that about 1 1/2 inches below the growing medium. I didn't have a way to adjust the water level on my strawberry's until I redesigned that system. Hope this helps some. It would be great if you could post some pictures when you get it all together.... |
yes, please upload some pictures, look forward to seeing your setup....

i will definitely post pics of the system once i get it going and the plants are big enough to see in a photo. i am still waiting for my grow tent and seeds to arrive so it may be a month or two until pics will be available. thanks for the help. :) |

I need to look it up to find out the name of the system that you plan on using but I have come across a few pictures that might give you some ideas. I call it a floating system because the most common way of doing it that I know of is inserting the baskets in Styrofoam and just floating the Styrofoam in the nutrient solution. You can easily change the height of the baskets by changing the thickness of the Styrofoam. In these pictures you can see a homemade system as well as a commercially built system. |

Update: This is the best on the internet that I can find right now but I found this: How to start on a shoestring and make a profit with hydroponics: including set-up, production and maintenance, and marketing by Hilmur L. Saffell. 3rd ed. (1994) As I said it was not a new book but it was a good book. |

Start your seeds in a rockwool cube. Once you have a few roots protruding out the sides of your cube put it into your netpot and surround it with hydroton. Until the roots reach your reservoir keep the water level, level with the bottom of the netpot. You should only need to do this for a week, maybe two. After that keep the water level 2-3" below the netpot. Good Luck. Any updates? Pics?
