Southern Clone Plight

I have growing for 12yrs now. I use Chris's Special Brew from Advanced Floraculture (BLOOM) products. I have had great success using them.
But, I cannot grow a successful clone to save my genetics. gone thru the gammit of machines, media, lighting, etc. I have media temp under control, dome temp and humidity also.
Here in the SOUTH we have serious humidity problems. Devices are wholly inaccurate because of the water droplet size.
This problem and angst, will shut me down eventually.
I am now using plug tray, Viagrow mat, tall dome and t5 bulbs (up to 4).
In need of EXACT directions, from type of water, all temps, LUX@ tops of plants, venting, humidity(RH) etc, etc, etc....

I will be forever gratefull to the one who will help me on my quest.
I seem to be the only one that uses Chris's Brew in the South, so you know that I grow quality, and I don't take sidesteps to achive it.
:wtf:I am part of the union, your brother needs help...
Thank you.
