Noob jumping in....what are the best all around substrate and spawn materials.

I plan on purchasing a controlled monotub and a few syringes. I'll probably DIY a larger setup later if things don't get FUBARed.

So after some research it looked like the cleanest and easiest things to manage are...

Light Karo Syrup
Coco Coir
Vermiculite
Brown Rice - Rice Flour
Gypsum

Looking for some tips on ratios, tricks....etc from seasoned growers.
