Hey there Jeremy! Your plants are looking really great by the way - Barney's LSD seems to be famous for those crazy white bunches of hairs most of the way through flowering!

1. First off, a common mistake is watching the plants' bud 'hairs' for amber colors to determine harvest time. What you want to look for is the color of the 'trichomes' on your buds, not the hairs. Do you see the 'frosty' coating on the leaves and buds? Those are the trichs which when viewed under a simple 60x scope (or a macro-lens camera), look like small stalks with a roundish head on the end. The heads on the end of these trichs are what you want to watch for the color changes. Clear trichs will appear first one they're starting to develop - then they will slowely change to whitish (cloudy) - and eventually a rusty (or amber) color. Most growers will wait for about 10-25% amber trichs before harvest. Clear trichs tend to produce a 'clear-headed, up-beat' effect from it's THC, while amber trichs tend to have more of the 'knock-out stone' effect... and cloudy is the transitioning color that's is medium between those two extremes. So by the look of your pics, it's hard to tell what stage they're in, but try not to go by the hairs, as this will not be accurate. At a glance, I'd say you have at least 2-3 more weeks to harvest, but try to get a close look at the frosty 'trichomes' to get a better idea...

2. That's a big question, and is different for everyone. Basically, ensure you have at least a good half-day dedicated to trimming. Get some good needle-nose clippers (Fiskars is the best) and cover your table-top or clipping surface with plastic to keep from getting everything sticky with resin. Use some nice white paper-plates to catch the close trimmed leaves that have 'frost' on them, so you can collect it all to make hash or butter later on. Setup a clothes-line type string nearby your trim area, and hang the trimmed stalks upside-down by the bottom branch-pits as you trim them. Then move the entire string of stalks to a closet or dry-dark area somewhere to dry for 5-7 days - avoid having a fan blow directly on them, but air circulation in the area is important... I'm sure I missed many things in between, so feel free to ask more questions!!

3. Answered somewhat above... remember that the hanging buds will smell quite a lot when drying (usually a smell of fresh 'hay' or cut grass clippings), so if you have a carbon filter from your grow, use that, or better yet, convert your grow area into a drying area!

4. Once the buds are dry (will feel slightly 'spongy' still, but also a bit 'crispy'), cut all of the buds from the stalks (now is a good time to weigh them all to get your 'dry weight') into bowls and them into your air-tight containers. You may notice them 'fogging up' a lot at first - be sure to open the containers every few hours at first (for the first day or two), until the cloudiness get lese and less.. what you're doing is actually 'drawing out' the moisture slowly from the inside of the buds, to get an even dryness... A good cure can last as long as 2-3 months or more - don't expect awesome tasting bud only weeks into the cure..

(gasp...) sorry for ranting - I hope that helps! I may write a book someday on these processes. =)
