ok so then how is dangling roots in the dydro section affecting all this^ compared to just straight chow dtw?
At one min feeds how much is actually going in what size bucket?Lost was a funny one, gave me some good laughs when i was really sick and there weren't that many to be had. Hope that cat is still enjoying life..
another thought, how will the dtw-rate affect these isssues JK just brought up?
i'm currently at 3min when they wake up, then 1min every hour until bedtime, manifold valves adjusted for slight runoff each time to hopefully make for ~10-15% total.
Times ratios are good to know but the amount running through is what we are after. different mediums dictate the amount of moisture. If I remember right you feed somewhere around 1700 ppm (i assume conv .5) Using coir that long it really absorbs moisture and holds it longer. You say your plants blow up but have you run some side by sides. I would think in my room if I feed a plant like that at night(lights out) with a 600 ppm at 6.0 pH for 2-3 days you would see better growth. Roots action is a 2 way street. Sometimes you need different pressure. Keeping track of a plants internal pH would help in this, if you have a few hundred fun tickets to play with. JKI personally am running 20 seconds on 1 min off during lights on in a 12 gallon container with 50/50 perlite coco. I dont check run off anymore. On my 4th round of reused. it comes out to about 2-3 gallons a day per site... something like that. The mix stays moist all the time and the plants blow up.

^kind of what i was getting at. the ones i mentioned are just small 1gal testers, haven't checked exact daily volume, maybe drinking .5-1gal each. just gave that rate as an example, doesn't really mean much without the other variables.Times ratios are good to know but the amount running through is what we are after. different mediums dictate the amount of moisture.

thing i'm curious about is how smaller container size interplays with nute ratios, esp K. above are in ~60/40 chow, happy up to ~2ec at 80F with no co2. I recently bumped them a little higher during pk-boost wk6/7, and started seeing Ca lockout from the high K (running close to Dankworth's ratios but diluted to ~.67). for this setup i'll prob run ~1.5ec next time with lower K ratio, then bump to 2ec with P/K and drop N completely (haven't decided exactly when yet). but not drop the Ca, will adjust that with CaCl2 instead of the calnit. might also play-with Ksulf vs Mgsulf while lowering the K.
if i had co2 in this tester-gig, ppms might be ~20% higher or so based on prev experience (closer to what i run for bushes/trees). with 70/30 chow in 10G smarties dtw i was used to running ~3ec, peaking around 3.5 (hoping to reduce this significantly as i progress with balancing the salts, while running tricks like iba/triac/bap6/fulvic/act/crobes/sar/etc)
sorry wasn't clear - for my setup, venting fresh air vs sealed/co2 forces lower rh and less than optimum vpd. hence my higher feed rate when co2 is on.Maybe I'm missing something here, but I never noticed CO2 making a difference in how my plants respond to nutrients. On the other hand, humidity did, Big time- higher humidity really made my girls want their nutes at higher EC values. Higher humidity (following VPD theory) made a big positive impact on the results I got from CO2 supplementation, as well.

i haven't compared exactly how high can push ec with vs without co2 (vpd kept constant), could be an interesting experiment. would you adjust for temps? too many variables for me..
Thanks for that insight. I will need two res's then to accommodate that.Times ratios are good to know but the amount running through is what we are after. different mediums dictate the amount of moisture.

JK, may I ask how you manage ph in an automated fashion? What device are you fond of for that task?
he never clarified by answerign my question. DO you only feed a lower ppm at night, or do you feed low at night and high in the day?
Thanks Quantrill. Been making it as a concentrate(veg) and running a pump in the res to circulate. Started out at like 4000 ppms for the res or something. Thinking I need to run lower EC to mitigate this. Of course been diluting this before feeding moms.the iron in yer res(Fe+++ and/or Fe++) is not attracted to magnets.
if it is precipitating, it is probably pH related. once it precipitates and becomes an oxide, it is then attracted to the magnet.
I water at night at lower ppms as the plants are sucking up some moisture to replace what they are transpiring at night. If they feed on high ppms they are absorbing nutes thru the roots because of the pressure imbalance,even though they just want water. I find doing this keeps the internal chemistry from getting gaked up.I feed higher doses when the lights are on when it can be absorbed,transformed,and moved easier.
Dankworth what does your root ball look like at the end of a run. I can not see my plants sending out fresh roots into that kind of environment. Thats higher then I feed my tomatoes at the ranch with killer rh and sun. And they are the biggest nute whores I have every run across.
What I shoot for is a simple premise I learned from Krusty. Stress Free growing will give you more bang for your buck then a lot of toys... Suerte JK
