Hello all who reads! I am starting a grow of 12-20 plants, I will be using a space under my house about 5Ft 11In in hight (Would be using LST) with a couple (2) different rooms that could fit about 8 -12 Adult plants per room. Now I was wondering if I could get oppinions on soil and mediums and also what type of filtered water should I use? Also I was pondering the idea of how i would be able to ventilate with only one hole which is how you enter/exit the “Down Under”.
Tangible or Not worth my time? Can get pictures and exact dementions but first wanna know if I should even think about wasting my time 
Anything is doable. Just depends on the starting point, what you want to do and how much your willing to invest. So it’s 2 rooms. You could use one for veg and one for flower. What are the temps and humidity like in the rooms. Is there electric? Enough electric to run what you want? Is there water access to install RO system? If not do you mind carrying buckets? There’s no ventilation? Does hiding the smell matter to you? Are you able to check them everyday?
Yes I am able to check them every day, no I do not mind carrying buckets, I need to get a humidity and co2 reader for it but will probably need some climate and humidity control Not much ventilation other then the hole down I spoke of Hiding the smell with carbon filters or fans don’t amuse me or need to be in place for my grow is under legal guidelines, electric can be accessed through out the house and use of extension cords Of corse im checking them everyday I live about them also ty for your time. 
How big is access hole to crawl space? Is it on the interior or exterior of the house? 
It sounds like a place that some maniac would bury his bodies…
Welcome to the community. If you have a controlled environment inside house with heat an air condition. I would pull my fresh air from the inside of the house For the grow space. Good luck with your grow…
Thank you and climate will probably be the biggest struggle.
Its about the size of a hobbit hole but opens up into almost full rooms just not tall enough to be very comfortable for the full grown plants.
Damn my friend why you gotta expose me like that the bodies emit a smell and waste that is beneficial to marijuana plants.
I think it’s too much waste, first process the remains for biodiesel, soap, bone meal, and “then” compost the rest…
