Did I miss it or have you said what ppm`s/ec yas`re runnin cuz them`s lil bitty baby fuckers compared ta when I put plants under HID`s.....and....
What I've been doing is watering until I start to hear nutes going down the drain... then switching the pumps off. If I only water twice a day and let 8-10 hours go by the second watering I can let the pump run for almost a minute (instead of 15 seconds) before I start to get runoff. That would suggest to me that they will dry out substantially (perhaps TOO much) in 8 hours. So I've been trying to hit them every 5-6 hours with short blasts, so that they can dry out (but not too dry) between watering. (But I don't know what the hell I'm talking about.)Yas might wanna feed lil less and let em set some more roots till end of stretch Bro...but maybe not....I don`t have a clue how wet/moist your 3 feed times daily acts with the lights and ventilation as in how fast it takes the troughs ta dry out kinda sorta between feeds for more explosive root growth.....
When I take cuts, I count down 4 or 5 nodes and then make my cut. Then I strip off all the leaves from those 4-5 nodes, leaving two leaves up top and then I recut the stem underwater taking about an inch off. What I'm left with fits into a jiffy pellet with just a quarter inch of stem and some leaves above the pellet. (They start out being 4-5 inches and end up being 3-3.5 inch cuttings.)I never had rooted cuts that small Bro , so I`m lookin at somethin new as well cuz that`s why I was askin bout ppm numbers....
Anti....I know all about budget so do the best yas can , but fortune favors the prepared mind , and it ain`t good ta play ketchup when your ph drops don`t work from bein too old after a while....so...
I`ve never put plants that small in the HID rooms cuz I hadta see how well they did under the T-5`s before prunin and shapin their ass sideways to even think about whether they`d make the cut for the big rooms....but....
Yeah....Ph knowledge is essential in ANY setup , but.....with coco....Anti, not to be all up in your shit but IMO Drip Clean is a "luxury item" and a pH pen is a necessity............people talk about needing to buy "ultra quality" pH pens but I buy the cheapo $15 ones from eBay and they last (and the good Lord knows, I'm far from cheap about most anything grow related).
Calibration solution is where it's at.
Anyhow, keep up the good work and knock this run outta the park.
Respect!
If you ain't got a fan controller - get one. I had some troubles with low temperatures and too dry air in vegetative period which all went away with a simple controller. There is a lot to choose from and i just happen to have the one which reduces fan speed in the wrong way - but it works.
Wrong: Same technique which is used in light dimmers. Causes slight buzzing sound.
Right: Costs a bit more but it does not cause buzzing.
