In my area you have to order online for black magic from hd
They have a whole display here. Convenient as I’m about 5 blocks away.
Awh man! Out here in sticks all they have is miracle grow! Anything organic you gotta order
That would sure make me interested in building my own soil instead.
New question regarding coir. Getting my soil ready & reading of possibility of needing to soak to remove salt. If this is case how long?
I’m gonna do a 1/3 coir, 10% perlite , 1/3worm castings (do I need to do anything with it before mixing) and organic soil with a .07% nitro.
New to indoor growing appreciate the help.
@Laurap the Coco and perlite are soilless and if you mix that with soil you could be setting yourself up for pH issues. Soilless medium is a pH of 5.8 and soil is 6.5 if you mix them together like that I think you’d have to consider that entire mix soilless?
Not sure on that but maintaining a proper pH on indoor grows is very important!
I thought you would mix perlite to help retain mosture and other for making soil light.
So I need to use one product or another, not in combination?
No, I believe you are doing fine but flushing the coir will raise the ph to a more useful range. I think I would simply rinse in ph neutral water and monitor the outflow until the ph is above 6.3. Then mix your soil. I will be interested in your recipe.
I also read of adding a pocket of more concentrated nutrients that the plant can hunt for as it grows. I may try that too.
Thanks, newbie here, so gotta ask questions. wanted to use bat guanna but hubby says no.
I’m more of a purist, hubby just wants me to stop spending money and grow. Lol
PS. Do I just check runnoff for pH?
Yeah, I would place the container in a pan when I’m ready to take a sample and capture some runoff.
