Note: i refer to delta-8 and THCa flower
From what i can tell vaping appears to be the cheapest way to enjoy your herbs. A d8 .510 cart is $12-$20 for a 1g cart and each cart has ~150 hits so each hit is $0.08-$0.14. Now edibles on the other hand sound super expensive. A 1000mg (1g) thing of d8 gummies is $60 for 40 gummies or $1.50 per gummy. Each of these gummies have 25mg of d8 in them. To vape 25mg would need ~5 hits and cost $0.40-$0.65. Or am i way the fuck off base and fucked up my maths. Always did suck in that class.
Edit: i have also heard that vaping is better because it uses much lower temps and doesnt burn off most of the terps before they get to you.
Indoor is not hard, you can pull 1 oz out of a 40x40 space or a spacebucket (the latter can be built for about 50$). A 60x60 tent can net me around 4oz every 3 months or so, although I grow 1 auto at a time for about 1-2 oz at a time, this is enough for me and the wife.
As for your calculations, my anecdotal experience is thus: 1g is up to 6 smokes for me, 5 g gets me 32 doses of edibles but the high is a bit more potent and lasts longer.
Yeah, thats 166mg per smoke and way to high for me. I am using a cart and 2 hits gets me where i want (im new) and that is 8-12mg. I need my tolerance to go up before doing much more. Made that mistake once and was convinced for hours my house was burning down. That was a bad night and i dont care for a repeat.
The math is off, you assume everything is a 1:1. Smokes only about 20% efficient in a flower that is 20-30% thc so cut that 166 down to about 10mg.
