<p>i started the big tank with minnows and crayfish, i had my oldest perch in a small system, i added 100 3" yp fingerlings to the big tank.. after they were acclimated (a couple weeks) i moved my large tilapia (10 blues) into the big tank, and my 20 or so large yp into the big tank</p>
<p>i bought 50 nile tilapia that were 1" in the spring last year, kept them in a single tote system until they were around 3-4" then they went in the pool..i haven't had problems with cannabalism adding fish that are 3-4" to the pool.. minnows don't last long, nor do the most of the tilapia babies.. but that was the whole point for me.. i feed the tilapia and the yp fish food, and there are lots of crayfish in the big tank (soon to be 100+ more crayfish) that reproduce.. i view the minnows, crayfish, and tilapia spawns as supplemental feed, and any tilapia fry that make it out of the pool will be used to breed my next generation</p>
<p>my systems are all in an unheated basement, in the winter the coldest the water has been (that i have noted) is 56f, in the summer i think the warmest was around 74 to 76f, i only heat 1 of my 55 gal glass tanks - the one with the tilapia fry</p>

<p>My aq system has been running 5mo. It's in a greenhouse. I have 2ea 250gl tanks and grow beds. I've used local fish small mouth bass and bluegill. I don't have heat up yet so I chose local cold temp fish. I'm grow zone 6 so my cold may be different than your cold. So I'm just starting to scratch the surface. I have to have some level of heat control to increase the fish/plants.</p>
<p>I'm almost done with a woodgas gasifier to run an engine. Heat from that system will heat my aq water and gh air. </p>
<p>The engine will run an electric gen to provide electric for part of our property.</p>
<p>That's what I'll be using for heat for my gh/aq.</p>
<p></p>
<p>For the winter you can double layer or triple layer if possible the gh. Just sheet plastic for 3-4 months or so. It cuts down on heat cost.</p>
<p></p>
<p>Insulate your tanks with at least 2" thick styro. Sheet Styro on the water with plants also insulates heat loss.</p>
<p>For night time you can use a timer to reduce the water to grow bed cycle since winter night is the coldest .</p>
<p>My recommendation is no matter what, have something for water heating that you can throw at water temp. Big temp swings or fast temp swings or low/high temps can drive you crazy with sick fish. Loose allot or all fish and where with the grow side be? So just a few watts to maintain temp isn't much.</p>
<p></p>
<p>I use a solar hot water heater for tank water now. It's a line voltage thermostat set high in the rafter/hottest part of the gh .</p>
<p>When it's warm enough it turns on a small pump that runs a black plastic line again up in the rafters where the gh is the hottest. That system gives just a little heat an the average solar day. When it gets warmer it will have to be run through an aquastat which reads water temp. That will avoid over temping the water.</p>

<p>Not sure on greenhouse size, but might be something like 300sqft. I haven't thought much about my specifc heat sources, but I know I'll need them. The woodfired heater is a good option, maybe a pellet stove. Also thinking about a thermophillic compost pile to provide some supplemental heat. That's all on my list to think on next.</p>

<p>What size is your greenhouse?</p>
<p>What will you use for an energy source for water/air heat?</p>
<p>Are you allowed to use a small woodfired water heater?</p>
<p>Based on your post tilipia win hands down. Even if your breed tank is indoors for cheaper heat cost that works out better than timing heat and light timing for YP. Unless you like the meat of the YP better? </p>
<p>For payback- go price a prime bouquet of head lettuce or tilipia fry (gotta watch selling fish in some states)…</p>

<p>For payback- go price a prime bouquet of head lettuce or tilipia fry (gotta watch selling fish in some states) (maybe sold live?). And the reason I suggest a little sales is those $ can go toward heat. I live in zone 6 and heat is a small concern because when the gh temp or water temp is mid or low,, the whole shebang slows down. And there's not much worse than watching a plant grow extra slow. <a style="cursor: pointer;"><img src="http://i925.photobucket.com/albums/ad93/ucsycybersmiley/24.gif"/></a></p>
