Stainless Steel Hydroponic Systems

Just want to introduce these Stainless Steel Hydroponic Systems to the forum.

I personally designed and fabricated these two systems to run in a 2' x 4' and a 4' x 4' grow tent. The smaller system is 10" tall, has sites for 14 plants and cost me about $300CDN in materials and components (pump, net pots, piping and tubing). The larger system is 12" tall, has 8 plant sites and cost about $550CDN total. All of the plant sites hold a 3 inch net pot which eliminates any chance of transplant shock when moving from the smaller veg system to the larger flower system.

I started with the smaller system first to make sure that it works before investing in the larger system. After working with plastic bucket systems and running into issues I decided to take all the positive aspects of those systems and reduce or eliminate the negative aspects I experienced.

How it works:

- Nutrient water is poured into the tank.
- Pump runs 24/7 feeding water to the header which in turn flows out of the feeding tubes.
- Water feeds the plant and funnels back to the compartment with the pump at the front.
-Water recirculates and is topped up with clean water as required and completely changed once per week.
- When it is time to change the water I attach a hose to the header at the front, open the valve to drain the system using the pump, flush with plenty of clean water and refill with fresh nutrient water.

I have been running the small system for about 6 months now with no major issues (just minor leaks from the blue feeding tubes). Everything grows very well, water temperature only reach about 26C max and PH fluctuations are minimal. I am using the 3 part General Hydroponics Flora Series and will be switching to Future Harvest 3 part system when I run out. I started my first round of flowering in the large system 2 weeks ago using the Future Harvest Nutrients with no negative effects so far.

I have found that the system is very easy to clean which is done when I move plants to the larger system. It is very easy to check and maintain water level, PH as well as the temperature and humidity of the environment. There are no signs of root rot or any deficiencies since I started using these systems.

Any comments or feedback is appreciated.
More pictures available if anyone is interested.

I think I would have gone with large Rez size but it looks cool. Like it could be in the back of Marty's car.

The base on the small system can hold about 10 gal but I only keep about 2 in there to minimize the amount of nutrients I use. The larger system can hold more but I still only keep about 5 gal. Since I change it once a week and top up every couple days (if I need to) it has been working great. This system could easily he used for DWC with the amount of water it can hold.

I like larger rez size. If it works for you awesome, as a general rule it's not an ideal design choice to grow that many plants with a few gallons of Rez. If you can spend $500 on this I wouldn't be worried about the pennies in nutrients.

I have a pretty good feeling this will pay for itself in the long run. How much water do you suggest for a recirculating top feed system?

Not bad don't take that the wrong way.....just hot and without a cooler you must have been cookin your hand

Admire the workmanship for sure.
Not sure how I feel about this though.
What talking about capacity you mean the rectangular part at the bottom holds that much right? Id probably want 20-25 gallons in the 4x4 system.
Does the whole thing not soak up heat from the lights?

Yes the bottom acts as the reservoir. The water temp only gets to about 26C which is the same as my air temp. Lots of air still getting to the roots and no root rot.
