Depends on what your soil temps are. Soil temps, not air temps, is what is important to germinating seeds. And even for transplants, short of freezing air temps, it is the soil temperature at root level that will determine if they will survive or not. There are many charts available both on the web and in previous discussions her on what soil temps are required for planting each different crop. Dave

You are correct, the only difference is the evap coil Mdl number. The performance/efficiency numbers for the 2 ton XV18i are identical. See below for comparison. You should note this is a communicating system that will require Trane proprietary stat for full functionality. I certainly recommend that. What Mdl has dealer quoted? I also recommend a Trane filter cabinet as well. 8704131 ActiveSystems TRANE XV18I TRANE 4TTV8024A1 4TXCB004DS3 750 565 415 *UHMB060ACV3 23600 13.00 18.00 1RCU-A-CB All 165 Yes 8736663 Active Systems TRANE XV18I TRANE 4TTV8024A1 4TXCB003DS3 750 565 415 *UHMB060ACV3 23600 13.00 18.00 1 RCU-A-CB All 165 Yes IMO

And just for fun, oil based polyurethanes AMBER. They turn ORANGE as they age. If you like the look of the colour RIGHT NOW, then you will want to work with a water based finishing system. Then there is the SMELL of the oil based finishes. They STINK. And they have a LONG cure time (30+ days). Imagine having a reaction to the odour? As someone who suffers from migraines induced by odours (ahem...perfume counters in department stores) I would stay as FAR AWAY from oil based as possible. The water based products also cure FASTER (10 days) and have much lower odour profiles (which dissipate inside of the 10 days). To be perfectly clear, a HIGH END water based system (2 part Bona Traffic HD or 2 part Loba 2K Supra AT) can double the material costs of the job. If your installer QUOTED you the job, s/he probably used the OIL BASED system as the base quote. If you ask for the HIGH END water based systems, s/he will have to quote an UPGRADED price. And that (in his/her experience) scared away customers. The staining products will need to be compatible with a water based system which is where the "white line syndrome" originates. The INCOMPATIBILITY of your profi's 'stain choice' with water based products is the deciding factor as to whether or not you will get adhesion failure. So long as the profi's stains are compatible with the sealant AND the water based polyurethanes, you should be JUST FINE.

Nothing, it's the same product.
