Ok I've always had the prenotion that cuttings don't and won't uptake nutes. But then I came to thinking if this is true, how come when you buy cut flowers, the florist will give you some light nutes to keep your flowers fresher longer (which it does compared to cut flowers stuck in a vase with plain old water). I am sure a lot of you have seen dyed roses and some of you know how it is made, the process consist of taking some roses and simply sticking them in a cup with food coloring. Same question here again, if cutting can't absorb nutes etc, then how is the dye absorbed throughout the roses?
I pranked my friend once, I told him that I got a hold of a super plant that produced never seen before color buds. What I did was cut a branch of a plant that was ready to harvest. Then I took that branch and stuck it in a cup with yellow food coloring. To my surprise it work better than I thought. Not only did the leaves and buds changed color, when I looked at the buds under a jeweler's loop (x30) I noticed that even the trichrome was dyed yellow. (I came clean to my friend and stopped him before he smoked the colored bud). I know for a fact that the particles in food coloring is too big (bigger than the salt particles in our nutes) to be absorbed by the roots, yet it can be absorbed by the branch I took. So back to the good old question...can cutting absorb nutes?
I've thought about this on and off for a while, but never took it too seriously. But serious enough to do some experimenting with some cuttings a looooong time ago. The test consisted of 4 groups of cuttings (from the same mom) stuck in cups.
A. Control group-plain old tap water (50-60ppm)
B. Light nute around 150 ppm (100+the 50/60ppm from tap)
C. Mid nute around 300 ppm
D. Heavy nute around 700 ppm
All groups were left under T5 about 1 foot away.
I did this test 3 times. Each time the results were the same. Group A and B look fairly the same as the day they were taken. Group C and D showed signs of nute burns starting from about day 6/7. The burns got worse and worse as more time passed. D as expected showed the most damage.
So back to the good old question...can cutting absorb nutes? I know a lot will say "No", but then how come the cuttings from my test show otherwise???? If they can't then how can we explain the signs of nute burn?
Was this a misconception that got passed on a long time ago and eventually accepted as "fact"?
Just curious......
