First Grow, Sip System Closet Try

So far the whole grow has been pretty frustrating. Firstly I don't have humidity control in my cupboard where i grew it the first 6 weeks, secondly I don't have extra heating so for about 3 days of every 7 days temps dropped to 8-12 degrees celcius definately shocked the plant and slowed growth. My airflow was terrible as well. and lastly, fungus gnats from day 1.. before i start any grow now I will have to clean everything sterilize everything. My worm bin has also been hit hard, I believe the person who sold me the worms already had a fungus gnat infestation, this was trasfered to the pots when i prepped the pots which was at night and i didn't realise the problem. I have to restart my worm bin also from scratch now. have to get most of my worms out, possible rinse in bacteria (the one that takes care of fungus gnat larvae) water and prep a whole new bin. I may sundry the old worm bin casting as well as spray it with some organic insecticide before sun dry so I don't lose 3 months of castings. I can still make compost tea with it. if i can get a fine enough mesh netting to make a compost tea without allowing anything through apart from the nutrients.
