@Alex in Alabama
We did our Nutrient changes yesterday and "Master Gardner" Kevin Price schooled me on Gardening so I have tons of information to report.
But, this Post is primarily for @Alex in Alabama who wanted to see a comparison between the Pepper Plants in the Hydro Ebb and Flo after seeing my Post on Wednesday about the "Buds" (Day 32: Buds, Already?) that are starting to form early in the HydroRush treated Pepper Plants.
Alex wanted to see comparions between the HydroRush treated Pepper Plants vs. the untreated plants. When I expressed to Kevin that I wanted to take some height and circumference measurements, he told me to "put on the brakes".
Although we can visibly see differences between the two Pepper Groups (Left: HydroRush plants are in the foreground – click on it to see a very large view), generally as you can see in the photo, the two groups are getting closer in physical size than when we first transplanted them.
…when we were doing the Nutrient change, the HydroRush reservoir water we were changing out was not as dark as the untreated reservoir water. To me, the darker color means more particulate material. The lighter color in the treated reservoir means the plants are pulling more particulates or Nutrients from the water that could explain the extra Nitrogen the treated plants are getting.
So, What Does All this Mean?
What the Heck Are We Looking For?
Me: What about physical measurements? Are they relevant in the context of this growing test?
Kevin: Clearly that’s one of the things typically of what people think of how plants grow. Plants don’t just grow in a linear manner; there are other things to be aware of. Not only are they growing in height, but also they’re growing in other areas like the actual surface area of the leaf that is expanding, which is a good example of a plant’s growth being exponential as opposed to linear (height).
What we’ve noticed on the HydroRush treated Pepper Plants and you have photographs of them is that we have more leaf-sets and larger leaf-sets on the treated plants than on the untreated plants and this is significant when measuring actual plant growth.
If we were to measure every single leaf on the two different groups, we’d see much more growth on the HydroRush treated plants meaning those plants are getting higher "values" than the untreated pepper plants because of the leaf surface that is available to take advantage of the growing environment.
Me: So, what I’m understanding is that typical height and circumference measurements are not as important as measuring leaf growth and leaf-sets to determine plant health.
The other thing we’ve talked about before and noticed is the early plant development in the HydroRush treated plants compared to the untreated pepper plants.
Another important thing that we have noticed is the appearance of early flower-sites. There are significantly more and better-developed flower-sites on the HydroRush treated plants compared to the untreated plants.
We could guess that this early development might mean early flowering and fruiting.
Of course we don’t know how this will pan out as time goes on, but we’ll definitely be watching this.
More importantly, as you can see in the photos the darker green leaves are indicating to me that the HydroRush plants are getting more Nitrogen into them so, I reduced the Nutrient levels to about 0.9 E.C. yesterday (with HydroRush added, the E.C. is 1.7). I also reduced the Nutrient levels in the Deep Water Culture.
Before you go, when we were doing the Nutrient change, the HydroRush reservoir water we were changing out was not as dark as the untreated reservoir water. To me, the darker color means more particulate material. The lighter color in the treated reservoir means the plants are pulling more particulates or Nutrients from the water that could explain the extra Nitrogen the treated plants are getting.
Me: That’s a lot of good information Kevin. I hope I get it all down.
See you tomorrow. I can’t wait to start pulling the plants next week and looking at the Roots.
