This is what I have always done, and this cycle has allowed me to have my "medicine" consistently year-around. If I smoke a reasonable amount and don't way overdo it (way overdoing it is what I'm the best at) I don't have to buy anything THC products: dabs, flower, vape cartridges, extract or edibles at all. The only things I have to buy are butane, sometimes a new globe and nail or new banger, soil, nutrients, sometimes new pieces, just to simplify it I only have to ever buy equipment but never the product. This is by far WAY cheaper than making trips to the dispensary or to a local plug. It's the difference between spending about $200 in a whole year or $200 a month (maybe even a week).
Alright so my year cycling begins in March because that's when I start ordering my seeds and decide what I'm going to grow that year. I'll use 2020 as my example: I was living at that time in Massachusetts, Cape Cod to be precise. It's a small town called Chatham and my ex-girlfriend, and I were in a winter rental. That year I ordered in September but only high yielding auto flowers. That year was the exception to the March start because it's freezing there and autos indoor is your only option until June when your plants can survive a night. I bought coco medium (3cu yds for about $40), and I bought 3 high efficiency, full spectrum, LED grow lights (they were approx. $25 each)(from Amazon), I did non-organic that time but even so I was running Fox Farm nutrients which I bought on Ebay (was a 3 bottle system veg, to flower, to ripen and cost under $33), I also bought colloidal silver, Super Thrive (under $12), sea kelp additive (about $14) , 1 digital PH tester ($11), a TDS tester($6), a digital scale($7), smart pots(five 10 gal bags for $30), and small desk fans (garage sale $2). (All of that up to the end ran me about $220, but much of that was either one time purchase or lasts a long time). Then the seeds I bought from 420 Fast Buds. I bought high yield, fast finish autoflowers. I would grow my plants, harvest, do a rough trim of fan leaves (while still wet) and discard those, trim the bigger sugar leaves and save them, dry out the herb and the trim in separately, do the more manicured trim (this is called a hybrid trim.), cure both my flower and my trim in separate containers, and then after a minimum cure of 2 weeks I would smoke the bud for the next 2 months or so. When that was almost gone, I would blast the trim. People think you need to use your buds for blasting your dabs but the trim works great. It also turns something that you have little use for into something incredible! You can also use it to make edibles, but I vote dabs are way better! I would blast 35g of trim and get back 5-7g of dabs. Then you just start the whole process again.
I'm not saying blasting trim is the only way to fill your extractor. You can also put big, beautiful totally smokable buds in there. It's just that I feel like that is a total waste. Because if you have great buds then you can have great rosin! I'll blog about that soon.
Those are your options for DIY BHO: trim or buds. If you're a mega baller, then just go to the dispensary and spend $3,000+ on tons of top shelf buds to put in there and your product will be fire af! But for the rest of us who arent pro athletes trim makes bomb budder or crumble. You can present your dabs that you made with trim to any serious stoner and he(she) will be blown away by how great it is especially after you tell them you used trim.
