Homemade Deep Water Culture Hydroponics System

video Homemade Deep Water Culture Hydroponics System

This is a DIY Deep Water Culture hydroponics. This is the first Hydroponics system that I built. the parts are easy and cheep to find. If you would like to see the progress of my hydrofarm please visit my Blog. www.robertbrennan.ca
Hi, the only practical place that I can put a system like this is in my outbuilding. It is usually frost free but otherwise follows the ambient temperature. Does the solution and nutrients need to be maintained above any particular temperature? Obviously I would ensure it doesn't freeze in the winter!

nice simple system, i like that it needs no water pump. how did you determine the fill line? how much of the pots should be submerged? can the air be on a timer or should it run constant to prevent rot?
thanks
In the beginning only the parts where the plant's roots are should be submerged. The air pump should more or less run 24/7 to prevent the plants from "drowning". Well as far as I know anyways. Also it consumes very little power so it might as well run 24/7.
Hi, I am planning on making this system but don't know what kind of nutrient to use. What do you use? Thanks
He's using "Advanced Nutrients Grow-Micro-Bloom".
Very nice video! Do you remove all the water and fill with new fresh water+nutrient solution or do you add more water+nutrients when needed?

I have recently started my own deep water culture system and so far the plants seems to like it. Have not run to the point when more water/nutrients should be added. http://apartmentgrower.blogspot.com

What size tub? You talked about a 44 liter lint inside the tub. I thought I would be on the same side and ask.

thanks for the comment. Any size tub would work that is more than 30 liters. this is a 52 liter tub with a fill line set at 44 liters

Hi, I was wondering what nutrients should be used for this project? Does the water need to be regulated so the pH doesn't kill the roots? thanks

Thanks for the comment. The nutrient that I am currently using is called "Advanced Nutrients Grow-Micro-Bloom" from a company called Advanced Nutrients. You need to regulate the PH but if you get nutrients like "Grow-Micro-Bloom" it has a ph buffer built in

Thank you for all the detail. I've researched a dozen websites trying to put a system together, looking for details in one where they were missing in another. This is perfect. Thanks again.

Nice simple system. one thing i would add is a check valve on the air pump. they usually come with newer pumps. Check valves are fairly cheap and will save you from a big old mess if the power ever goes out.

one thing you want to make sure about is the grown size of the plants. the size of the pots you are using is what i use for cloning as the plants themselves will grow to large size and crowd each other out. they will be growing very fast when you get up and running !!

thanks for the comment. I have had this system running for a few and find that the size of net pot does not matter all that much as the roots have all the freedom that they need the the bottom tote. I do agree that if you plan on big plants then you could space out the holes for more room in between. I added some pictures to show what I mean
