Yup! That right there is the beauty of hydro, combined with TDS readings.Thanks in no small part to you @Rexer auto Sensei. So I’m learning something new about the hydro every day. Can you grade me on these impressions (confirm their accuracy or correct, please…)?
1. As I watch the TDS numbers I realize I am watching them feed in real time. And at this point I am beginning to be able to tell the rate with which they’re feeding. For example, a couple weeks ago they were just chomping everything in sight. The TDS number would go down each day by like 30-50 points. That seems like a crazy lot to me. Now they’ve slowed and are eating around a 10-15 point difference a day. Last night was 180. Now is 166. So is that one way you gauge what to feed?
Most have to wait to read the leaves to see if something is a miss. When youre taking TDS readings, you can tell something is off just by how much their feeding. You have a window of opportunity to fix problems, before they mess up the leaves (not to say it won't still happen- just less frequently).
As long as she's eating and drinking you're in the clear more often than not.
Youll see the biggest drops after a fresh reservoir is done. This is because (and this is just a guess), everything is in perfect (or near perfect) ratios and PH should be bang on.
Mine usually slow down a bit when the res needs to be swapped for fresh nutes.
When shes near the end of flower she'll slow right down on feeding (unless foxtailing).
I'm a bit confused on the question to be honest.2. I compromised the roots with my setup. The largest mass of them is concentrated in the pot under the lower coco. This only allows them to come out into the res out of the holes I drilled. And they are, in droves. But I know that air stone is covered with roots. And I suspect the plant would be happier if it were just the res by itself, yes?
Thanks Rexer!
Heres a bit of a taboo subject.
Roots and how they adapt to their environment.
The plant knows what balances of types of roots are needed to survive and thrive. Given time, plants adapt their root mass to their environment.
here is a personal challenge if you have spare time. And i encourage anyone to try it.
Use a cheap lettuce seed to cut the costs. This is for learning.
Hydroponic Kratky method, in a small simple setup.
Take a mason jar (or old peanut butter jar) , and black it out using tape or paint. I like tape as you can make a viewing window.
Cut a hole in the lid or make a lid to set a net cup in it.
plant your lettuce in the net cup. Fill the jar with a mild grow solution (150PPM).
The fill line should be just below the net cup, so its almost touching.
stick it under a light.
Thats it. No airstones, nothing fancy. Watch the plant grow, and how the roots develop.
the plants will grow air roots to breathe as the water level drops in the jar.
I had hoped and planned to do a 50 gallon Kratky grow this summer, but wasn't able to.
oh and the name (Kratky) is based off the professor who came up with it... professor Kratky.
Believe it or not, some of the biggest root masses I've seen come from this method. I really wish I had been able to do a plant in one this summer!
Your in for a treat- I consider it a classic like Blueberry. I actually have one seed left that is a Blueberry x White Widow cross....I need to reverse that one with some STS or CS.Believe it or not I have never even smoked White Widow before!
