So the guys at UC are preaching a system where you mix up the next weeks nutes ahead of time and then use that to top off your system via a float valve. They say that this method is better for a number of reasons.
1. You can adjust the top off res's PH so that as your system's PH creeps it will offset the change in PH (this would require some fine tuning).
2. You save water and nutes because you don't empty the system and refill it each week.
3. You keep all of the good microbes healthy and thriving throughout the grow instead of re-establishing them each res change.
Supposedly the big tomato farmers are doing this right now and it works great for them. They do a 50% res change 2-3 times through out the entire grow, veg and bloom.
It sounds like it makes a lot of sense. I think there is an article on Urban Garden about this technique but I can't find it....
Jack and everyone else, what is your opinion on this?
I have run 4 16xl undercurrents with 16k in a sealed room with all the goodies. As mentioned by the guru above this system is NOT meant to have 27 different hocus pocus additives. It is optimal with your favorite A&B along with one bloom booster/finishing agent and cal/mag. You can run all the side by sides you want and you will not beat this kiss method. All those additives and sooner or later white slimy roots will overtake this system.
Call me what you will but this recipe specifically for the "undercurrents" will blow it out of the box everytime.
DM gold A&B
Big Bud
Overdrive
Magical
Nothing more or less, you can thank me later and save a ton of dough in the process.
Is this your flowering room layout? What kinda of lamp in the parabolic fixtures? Awesome system you got there!!

Man that looks so cool yep thats it..Im thinking of cutting out the parabolics during flower and using the six extra 1000 watters on the out sides...JACK
I have flushed 1 time in between veg and flower the plants really responded and loved it..I will do so again as needed, Top off at full strength give or take 50 ppmYo Jack is the top off nutes at full strength? Also so you do not do any flushing I take it.
Walking into a room with 30 x 1000 watts makes you take a step back..:pimp: I will come up with the decision tommorow I may try one side with and one side with out and see what the yield difference is...JACKCome to think of it I like the sound of turning on the (6) 1000's and the parabolics.:sun

L-Immortal: Did you use DM Gold Grow A&B andFlower A&B? Or just grow? And could either Big Bud or Overdrive be replaced with the new AN Kushy Kush? Any other specifics you could give a newB about to start his first UC grow?
BTW, nice grow Jack!
