The only way i can get trout to work is to move the waste heat upstairs to the room with the tilapia. Pretty easy since it will be right below that room. Just have to insulate the lines from the lights up to the room.

I meant the fish growth rate but thats good info too lol. How long have you had the system running?

Ok now i need to know things like temp ranges of the basement and water. I was looking at doing trout and i have a completely open basement that sits at low 60s year round. Also what kind of growth rates are you getting?

I found some pretty good suppliers of up to 50% protein feed made from ground up fish pretty much and its less than $1 a lb. Shipping kills the good price though. Where are you growing brook and rainbows?

I wouldnt eat those though lol. I mean koi can be worth a pretty penny when grown to a decent size so its possible they would be worth it. Goldfish are only good for.... I honestly cant think of anything. They are cheap young, cheap big, and arent edible.

That was going to be my choice, but someone at work was begging me to do trout. I was very interested in seeing a fish with a really good conversion ratio grow almost pound for pound with their food intake. But catfish are pretty good too. I think it was about the same as tilapia.

Young tilapia fry will eat algae right out of the water. Catfish actually dont do much cleaning. But just leave the tanks covered and paint them so light cant go through. I have an open tank with light going right into it. worst case add a pleco or 2 once you see algae getting bad.

Trout actually grow pretty fast weight wise, they take forever to mature though. A trout in their last 2-3 yrs to maturity can gain almost 10lbs. Even with the first year only doing at most a lb, the next 2-3 years more than make up for it. Then again, I have trouble keeping trout alive yet...

Yea, and who knows, the drop in price may reach a point where herbs may be more profitable anyways lol. Around here there are dispensaries almost every block it seems like. Weed prices are plummeting here and Michigan is pretty strict still on those laws. Plus i could just imagine growing some...

If you are looking at warm water, tilapia, catfish, and bluegill are the main ones. They have a very good FCR and can tolerate a lot. You need a fish with an FCR of 2 or less because if they dont convert food well, then you cant stock them at very high densities, and they will grow slow yet...

Nobody doubts the leds working well, its mainly the temp control (for plants and fish)and cost of power for lighting and heating that is the question. Thats the 2 problems i think are the only reasons deterring people from doing this. That and traditional farming allows for a large harvest and...

We actually have lakes here in Michigan stocked with trout, but yea, the trout require high levels of oxygen to survive. Its actually the reason they die in warmer water, the DO levels saturate lower and lower as the temp goes up. Above 70°f, there isnt enough ability for the water to hold...

I think he wants a year round greenhouse that is kept warm like a building. Its hard either way i think. One you have to do mostly artificial lighting so lighting is much higher. Other hand, greenhouse would require more heat than the leds can supply but it wouldnt require much lighting. Thermal...

I've been busy the last couple weeks trying to get my boat running reliably so i havent given any updates, but the pepper plant did finally take root after a week and is producing peppers already. I have wanted to try trout, but they are so hard to keep happy. 1/3 of the trout i was getting for...

What leds do you have on them? Any specs?

Then thats a majority of the cost. The other equipment is fairly cheap. Growing medium is your next huge hurdle.

I think the warm climates of California would be perfect too. Im amazed that these systems never took off over there. It would be very profitable not having to worry about climate factors. Im looking at trying out trout as a cold climate system but i couldnt put the heat from lighting in the tank.

Starting off modular with making your own lighting system would be the cheapest and best route i see. Taking money from anyone always comes with strings attached. I dont have the space to do anything more than a couple systems and i dont have deep pockets to get more area so i'm not going to do...

Most definitely would be. I could see a greenhouse that could use the sunlight during the day and extend growing hours partially into the night time. This could allow crops to be produced even faster with minimal power used for lighting. Any other form of lighting would be big, hard to mount...

True. I want to leave it alone, but i want to document it as well. It is definitely slower growing, but the plant looks well so thats good.
