I am not sure on the brassinolide. Seems over priced and what not. Now the Triacontanol, Is some good stuff.
Save your money and buy some Alfalfa and make a tea from it. I put a couple or three handfuls of hay and add water stir a couple times a day.
Day 2 I add 1/4 cup of Molasses. Stir daily. After 4 to 6 days I remove the hay. I have also added rabbit manure to this brew and have feed just this to my tomatoes.
1/4 gal. of this to 3/4 of a Gal. of water Spray or root drench.
