I
don't understand what the method is guys? Are you using BRF and vermiculite and using that as a substrate? If so, it will likely work nicely but... your substrate is not as nutrient filled as it could be - so you might not get the same great yield. Pure grain gives you a high nutrient value - actually the highest you can get unsuplemented - but as I have said, the limiting factor is moisture - grains just can't hold enough water to really get the big flushes you want (well, they can be very substantial). Straw can hold the water but it doesn't have the all out nutes - what it tends to do however, is give you very large fruit. Now, if you suplement your spawn, supliment your substrate at spawn or suplement at casing you can get incredable results. I have found your best suplement is cornmeal or cotton seed meal - 5 to 10 percent - if you do this, be sure you lower your temps as your trays will really heat up for a couple of days.
