Same here. I use Promix hpcc and add 20% small perlite, 20% large perlite and 5% coco coir. At 80 degrees and 50% humidity I can't go over 24 hours. I also feed 2-3 times a week at 1600 ppm and no burnt tips.Use pro mix HP high porosity no vermiculite just straight up perlite at 78 to 80 degrees she will drink all that water up like no tomorrow and if you want add a couple heaping cupfuls of perlite or use sunshine mix [HASHTAG]#4[/HASHTAG] it is a very porous soil less mix no vermiculite A/N use sunshine mix [HASHTAG]#4[/HASHTAG] with all there soil less grows it is what they use to run comparisons and what not. I have even used pro mix bx which has vermiculite in it to retain water but just add three cups of perlite to a five gallon container and she will soak up the food great but the last method is only if I cannot get pro mix HP which is what I have used for years
