Are you sure it says 5 milliliters of TRIA and not 5 milligrams?Thanks Dizzle for this great thread! I have a kind of stupid question. I have this product, that has 5ml of triacontanol per liter, how do you calculate the ppm's? Is it by molecules, weight or volume? It also has 490g of ethanol per liter, 18g/l of n-butanol, a little urea, ureaphosphate, iron chelate, aminoacids, surfactant and the rest is water. The proposed usage is 1 part product 4 parts water and used as foliar spray once a week. Thanks!
edit: While I'm at it, I might just throw another stupid idea. What do you think about using the stretch inducing gibberrillins to control the height of bushy slow growing indicas? I think it could be beneficial, if you have stretchy hybrids or sativas in the same grow space, to have another control tool for canopy/morphology management?
I don't really have anything to add to this interesting thread yet, but I have a bunch of Vanilluna of which one is totally done now at eight weeks and the rest have a few weeks longer to go... I just ordered some JAZ Rose Spray and I can't wait to spray half of the plants and see what happens at the very end of inflorescence!
Yes 1 vial (1ml) per gallon should give you ~.066ppm which i would consider a good dosage. However i did a little side experiment with 3 clones that i had that i had no use for where i decided not to water them to show how EBR effected water stressing. there was one pant that was the control, a 0.050ppm and a 0.100ppm. the .050ppm plant lasted a whole week longer than the control before wilting, and the .100ppm group lasted an extra 3 days past the .050ppm group before wilting. One thing i noticed was that the highest test group was significantly the shortest plant, but had the most foliage/mass, suggesting that epibrassinolide reduces stretch (cell elongation), although Spurr has commented on the exact opposite happening when over-applying Brassinolide... I personally would give higher doses if expecting significant stresses for the plant.Thanks for the update. I got a few vials of epin from Top Tropicals. Sounds like there 1 vial a gallon is good.
What do you think of the Cirkon? I grabbed a few vials just for the hell of it. Most of what read on the active hydroxycinnamic acid was pototo and brocli studies.
Im not aware of microbial degradation being an issue with 24-epibrassinolide, i know that it doesn't degrade in water over time, unlike its more active cousin Brassinolide, which is why i use epibrassinolide.My next test I will be using a NIS and a much lower dosage. When you mix EPIN do you have to use it fast because microbes break it down quickly? It sucks that I mix up a quart and only use a fraction of the mix. Seems very wasteful. Is there any way to preserve it? Maybe mixing some kind of preservative in there?
Well it took some time for the changes in growth to be significant enough for me to see with my eyes, but finally i have results. Keep in mind that all testing has been in vegetative stage, and all plants have been dosed with 1.0ppm Triacontanol every 2-3 weeks. The Bubblegum is a squat, bushy plant, while the Blueberry Diesel is a tall, robust strain. There has been 2 EBR applications, the first a few days after being transplanted into one gallon pots, the 2nd being 40 days after the first and 2 days after plants were transplanted from 1 gallon to 3 gallon pots. Changes in growth were much more apparent and arose much quicker in the Bubblegum cultivar than the Blueberry Diesel.
Height was completely homogenous in all bubblegum cultivars, as was leaf and stem color. However the Bubblegum control group began to show significantly less dense foliage than all other groups (less branching, leaves, nodes), and significantly less root development than all other groups. The group that received the largest dosage (0.10ppm) had very slight physiological mutation where one side of a leaf would grow faster than the other side and lead to a slightly curled leaf. this was probably on 2-4% of the leafs in the 0.10ppm group. The 0.10ppm group also had slightly less dense foliage than all the other groups aside from the control group, however root growth was on par with other EBR groups. The .025, .050 and .075ppm groups all had identical top growth and root growth (as far as i could tell), until transplanting and the 2nd application took place.
There were larger discrepancies in top growth and root growth of individuals within test groups of the Blueberry Diesel cultivar than differences in growth between test groups, from the control group to the 0.10ppm group. However upon transplanting and the 2nd dosage, the root growth of both the Bubblegum & the Blueberry Diesel groups became much more homogenous for individuals within groups while differences from group to group have greatly increased. The .075ppm EBR groups for both the Bubblegum & Blueberry diesel had significant increases in root growth over all other groups, followed by the .050ppm groups and 0.10ppm groups. The .025ppm groups have better root development than the control groups but it it significantly less improved than the higher dosage groups.
With these results i am fairly certain that the .050-.075ppm range for 24-Epibrassinolide is optimal for cannabis cultivation, with the higher range (.075ppm) most likely being better once lower ranges have been ruled out to not be supraoptimal. This is not of surprise, since 0.1uM (~.0481ppm) is the most tested dosage with successful results in experiments, and when slightly higher doses are tested in more accurate experimentation they often have better growth than the .0481-.050ppm (0.1uM-.05mg/l) groups.
