Not sure what else to say about it but interested in your thoughts and willing to answer any questions to anything I maybe should have mentioned
It looks like you're off to a good start. I've grown in Miracle Grow with good results. I don't use it now, though, because I don't trust the ingredients. I've been recycling the same soil that started mostly as FFHF and
FFOF. I add amendments, as needed. Fill your pots nearly up to the top, leaving an inch or two for top dressing nutrients. I don't recall seeing nutrients mentioned, but use of mycorrhizae means you're planning to use organic growing methods. I use and recommend
Gaia Green All Purpose and Power Bloom.
I mount fans and filters outside the tent because I like to have ample vertical space, and I like to have more room for the light. Lights usually don't need fans, but a way to exhaust the heat from them can be important. The
ViparSpectra lights I've been using have a heat sink at the top, so I installed 80mm computer fans on top of the heat sinks. That has worked well. Small power supplies for them can be found on Amazon.
Also got some mycorrhizal to mix in with this one. A quest, reading this expensive mycorrhizal packed, I'm going to need to put the entire thing into 1 pot?
Only a small amount is needed. The organisms grow and reproduce if conditions are right for them.
The light isn't on yet. When they sprout I was going to turn it on and raise it some 18 inches
I'd say to have it about 36 inches above sprouts. What does the light's manufacturer recommend? Keep in mind that the most intense light is directly under the light.
I know this is a costly hobby but the idea is to save money on smoke, eventually. But a question, how much would you expect to spend just on setting up your medium?
I had the same motivation when I began. It has been a while since I last checked the local price of an ounce of bud, but it adds up quickly while my wife can go through several grams a day. There's also the fact that we know what is used to grow our own. I can't say I trust whatever commercial growers might use. I also prefer well-ripened buds. So, there's more to it than saving money. That said, at this point I have no idea how much I've spent. I could have spent less, but experimentation is fun. I also discovered that it's easy to grow much more than we can use, so we give some of it away. It didn't take us long to get several pounds of bud in storage, and that's too much for us. We also like to try new strains—there's so much great weed out there waiting for us to grow it.
Incidentally, we rarely smoke these days. We mostly vape and make tincture. We've made some amazing tinctures by blending different strains.
