Rockin those brods!
Are you educated on plant morphology & anatomy? Here is some reading for you Sherlock.
Structure and Development of Stomata on the Primary Root of Ceratonia siliqua L.

Abstract
Stomata of various sizes are produced on the primary root of Ceratonia siliqua L. Most are generated during embryogenesis, prior to seed desiccation. They can be detected on the dry embryo in a wide zone just above the root tip. Initially, large stomata are formed. These have the ability to induce divisions of their neighbouring cells, creating particular cell patterns around them. Later, small perigenous stomata are generated. As the root grows following seed germination, the stomatal zone overlaps with that of the root hairs. Although root stomata of C. siliqua undergo a structural differentiation that seems almost identical to that of the elliptical stomata formed on leaves, they are unable to move and remain permanently open. Polarizing microscopy of fully differentiated stomata and young stomata at the stage of stomatal pore formation revealed deposition of radial cellulose microfibril systems on their periclinal walls. However, these systems were less developed than those on leaf stomata, a feature that might be responsible for their inactivity. Besides, plastids of the root guard cells (GCs) do not differentiate into chloroplasts but function solely as amyloplasts. Root stomata have a short life span. During rapid and intense root growth, GCs cannot keep pace with the elongation of their neighbouring rhizodermal cells. They therefore split in their mid‐region, transversely to the stoma axis. The two parts of the transversely torn stoma are dragged apart and a large opening is formed on the root surface, just above the substomatal cavity. The root stomata, together with these openings, may facilitate increased gaseous exchange during respiration and/or an increased transfer of some nutrients and water in the rapidly growing primary root.

yup that's fer sure first semester botony.
As a rule roots don't have stomata.
a very few plants have been found that do have some stomata on the primary root, but never below the root hair zone.
back to your regular program now, believe it if you choose.
cheers :cigar:
so do you know if cannabis is one of the "rules" to this exception since we aren't talking about plants in general?
just wondering since you seem so positive there is no stomata if you have some science to disprove babas article or are just assuming cannabis does not?
Is this second semester botany stuff because I don't know if I am quite ready for that.
If I had a root right now I'd just toss it under the microscope. Anyone got both? Can clear this up right now.
Hey guys I was wondering why has the nute line picked up steam at the farm here. Its been out for a while and Ive never really heard rave reviews about(mixed bag) just wondering what is drawing people to this line?

BaBa G did a thread & I peeped it out.. after the thread I smoked both his samples>>>>> cherry pie grown with & without nectar & without nectar was juss like my cherry pie >>>> but the nectar grown cherry pie had a interesting more sticky look & it was a very bomb. . Plus Scott hooked me up with 2 free cases 2 try. .Hey guys I was wondering why has the nute line picked up steam at the farm here.

Anytime i see a respected member or better yet a respected breeder trying things and getting results that are impressive to themselves. Im up for it.Hey guys I was wondering why has the nute line picked up steam at the farm here.

FWIW I sprayed the Bloom Chaos maybe once in early flower right after switching the light timer. I did foliar with True Blooms about 4 times in the first 2 weeks of flower but I don't like the way my plants behaved after using the Bloom chaos foliar and yes I used plenty of calcium in conjunction. I do use the Bloom Chaos as a root drench every 7-10 days during flower. Different strokes for different folks though...so do whatever your plants tell you :DBaBa G did a thread & I peeped it out.. after the thread I smoked both his samples>>>>> cherry pie grown with & without nectar & without nectar was juss like my cherry pie >>>> but the nectar grown cherry pie had a interesting more sticky look & it was a very bomb. .

I do foliar with seaweed or fulvic acid every other day when plants are in veg.I almost never spray anything on my plants, I might once a week spray very light with doktor doom knock out for preventive measures.. But that is it. very, very lightly
It seems like its really easy to fuck shit up with foliar feeding, so I would just rather not foliar feed.
Don't fix what ain't broke, right?
I can already tell this is gunna b a tuff grow log bcuz of all the crazy names of the bottles I have 2 keep going back 2 double check how the fuck 2 spell the crazy name<<<<>> its fuckin wit my flow.. it stops my thought pattern bcuz i have 2 stop & check juss 2 spell a word... grrrrr!!!
