HARVESTED EARLY - WHAT WILL THE EFFECT OF THESE BE??

Would be better with more pics and some zoomed out ones. All trichomes have THC in them, clear has peak THC but not a lot of other cannabinoids, cloudy has some mild THC degradation and some cannabinoids and amber has more THC degradation and lots of other cannabinoids. If the trichomes where a mix of clear and cloudy you'll be fine. you will get high. The image you uploaded looks cloudy to me with some clear. 12g wet is not great, I find normally 1/8th to 1/12th is the dry weight from wet. so looking at like 1.5g-1g dry from 12g wet. This would be good for a single blunt or a few pinner joints. but not a lot for edibles. You could infuse it into a small bit of fat and then cook with it all in one sitting and feel a little bit of something but would be easier to get more weed from a dispensary and infuse that into the fat as well. Or just make regular brownies and smoke a J. The weed will want to be cured for a bit or its going to be really raw and harsh. grassy and not smooth. In the end you need to buy more weed to get your buddies high. get a 3.5g-7g of w/e is cheep and make brownies with that or smoke a J of it. I've made quick infusion hot chocolate with single grams and they are fine for me. Nice and mild and light. but split 4 ways would be a stretch. aim for 1g a person. and infuse it on low over 2 hrs. in fat. so butter or oil. then use that in w/e you are cooking. filter out the plant bits after. If you have a ginrder that has a lot of crystals in it. use them up. they are potent.

Nowhere near enough to make brownies that will have any sort of effect.

This isn't particularly too early. If you harvest now the plant should be at it's peak potency, THC-wise. So for inexperienced people, it might even be better to wait a little longer. You will also harvest a little more and it might just have a little more aroma to it. If you choose to wait.
