I just wanted to get some advice from my fellow trichocereus growers. Those of you with beautiful grey blue specimens how do you achieve that color. Is it more to do with your genetics? I have some beautiful cuttings I have acquired over the years that are blue but I've never grown anything from seed (90% Bridgesii/Bridgessi hybrids) that has taken on that coloration. I'm assuming it has to do with the extreme strength of the sun where I live. Lately I've been giving my plants shaded dappled light with an 1 hour or 2 of direct each day and check new growth regularly.
Thanks in advance
