morning i live in the desert ca , what’s better to use the perlite or vermiculite in my out side soil , yes i am new ,lol it gets hot here june to sept 95 to 110 F every day , or is mixing better ? thank you all for your help .
Vermiculite holds water a little better, and offers more benefits than perlite.
As covert said, they are usually used for 2 different reasons, vermiculite for water retention and perlite for aeration.
Are you growing in pots or in ground?
25 gallon grow bags , and it gets hot , so i double the bags up 1 inside the other
Perlite is a great idea as roots need oxygen. The more perlite you add, the more often you will need to water.
I believe vermiculite properties allow for more water retention, so the more vermiculite the less you’ll need to water.
If your grow bags are black, you should consider painting them a lighter color, flex seal type paint works great.
Also if the bags are on concrete, it can get hot. An elevated stand could help to keep them off the heat.
I agree with the above poster. I ran an indoor white widow dec-feb. I would take her outside every sunny day here during flower. First couple times I noticed the tent would get very warm the first couple hours after I brought her inside. The soil was getting pretty warm from that 5gal fabric pot sitting in the sun and that was Jan/Feb. I rigged up a way to shade the pot when she was outside and the issue with the hot soil went away immediately.
For my outdoor garden, all winter I have been dumping my used soil and run off water in the area ill be growing in.
thank you all , yes i will get them off the slab , and get my black bags covered
Pumice stone for the win.
