MaxiBloom. I know there are other nutes that are cheaper but for ease of availability in most areas the 16 lb tub is a good value, IMO.
glad to hear you got it all down, bro. Someday I'll dig mine back out and give it another go....prolly in Winter so I can still avoid the chiller routine...LOL
rock on

Thaks for the vote of confidence, but I'm FAR from having it all down!
I come from an engineering background, so when I got and installed a chiller, I overbuilt the living shit out of it- I have a 2 Ton Chillking, and it cools all my growing spaces AND all my RDWC systems, lol
The nutes Snowblind turned me on to are called Peters Professional hydroponics. The stuff is ridiculously cheap ($40 for a 25lb bag?!), lab grade pure, completely soluble and it isn't packed with a bunch of pH buffering crap that bumps PPMs but doesn't add to plant nutrition. Plus, the people working there are extremely knowlegeable and are used to working with universities and research facilities. In other words, they know their shit in ways AN and most of the rest of the hydro nutes world can't begin to keep up with.
I had a couple of conversations with them and came away very impressed. This is the tuff wholesale greenhouses use, and if you dig around in a major city near you, I guarantee you'll find a wholesaler who carries them. If not, call JRPeters and they'll be happy to list off several in your area.
The mix I use is the Jacks Professional 5-12-26, it comes with all the chelated micros in it. Add a good quality Calcium-Nitrate, such as Jacks Professional 15.5-0-0 Calcium Nitrate, and that's all your plants are likely to need. Period. Here's the kicker on this stuff; it's concentrated to the point where you need your gram scale to weigh out the nutes; it's like 3 grams per gallon! And at $40 for 25 pounds, we really are talking pennies a nute change, even in big volume RDWC like I'm running.
This stuff is a life- not to mention wallet- saver!
