I strongly encourage you guys to go easy with the teas, and I can not emphasize enough how important it is to let a really strong mix cook/cure. The time and resources need to be invested up front, without trying to replace it with any mix/concentrate in a bottle or a bag. If you can't afford everything, it is better to wait until you can, rather than substitute.
New or improved organic amendments will show up from time to time, and they are always worth investigating. There are phenomenal new, organic technologies regarding improved availability of nutrients to plants (i.e. Biozome, Humic DG, etc.) that are coming out regularly, so it doesn't have to be boring... there are always new amendments worthy of consideration to add to your mix. But, if it looks like a short-cut... I advise extreme caution with regard to the integrity of your mix.
This is the best piece of advice given over the entire 7 pages. This is something I understood right away and am very grateful for tx stressing this point to me. Switch over to TLO slowly while using your current set-up if you're interested in TLO, buy amendments little by little. I have 4 of my amendments so far out of 16 that I need/have planned. Not including my soil base. (Will be SS#4) I figure by the time I move in October I'll have everything all set and ready to go so when I start up in my new place I can just run TLO from the jump. I'm going to let my mix cook 30-45 days before I move. Not that suspicious to move a trash can IMO.
Also, if you haven't gotten in 7 pages that TLO isn't about feeding the plant as much as it is having a good support system for your beneficial bacteria and feeding it - go back and re-read these 7 pages. Teas are great but they're not the point of TLO. Teas should be simple not extravagant. This isn't hydro or soil-less the best and most used feed is plain pH'd water.
