4 Inches is all them girls need?

I'm not saying it doesn't work (air pots or any kind of pruning pot have shown to be superior) but I struggle to accept his notion that 4 inch pot is the key to growing big plants. Obviously the tree below was not started in a 4 inch pot and is clearly not restricted. If you start seeds and allow the tap root to root bound in a small pot the tree (and as your guy showed) mj plant does not reach it's potential, I've seen the vids on that. I'm just saying I think the guy has found a ''minimum'' pruning pot size that reduces or removes that effect and took it to market. From a marketing stance where else could he go?. Air pots of bigger sizes are already well established so the smaller ''rooting'' or ''germination'' sizes is probably a good gap in the market. Crop count issues probably also played a part, I imagine tree nursery's want to fit as many into a space as possible during that low foliage root development stage. But that almost sog like approach does not suite every mj grower.


I hear you BUT NOW IMAGINE IF THAT TREE HAD BEEN! :)
Also i didnt see anywhere where Dr.whitcomb lets a plant BECOME ROOT BOUND

If anything this is what he is fighting, GIRDLED LANKY ENCIRCLING roots

And if you actually whatch his videos (i know it takes time to watch)
He is really agaisnt crappy nursery trees

is this not the original vid that you wanted us to watch ....bummer I'm lost?
Yes that is the vid i mentioned in the first post.
This is where i discoverd the method

But the DR. Actually gives more in depth break down of whats going on

Im tech stupid ill try and post a link lol

Your good vostock your not lost budd
I typed a shitload in the first post lol

Will try to post pics later(maybe) grew some sinmints that way but I quite didn' see much difference as i wouldnt have: used the rockwool until the roots branched out from the sides, transfered into moist coco allowing it dry n only continue watering only the rockwool allowing the roots to run through coco freely in aeration until completely dry, then continue to water whole medium an as usual.
Never seen anyone take it to that level of "f***n roots" as he states, either, dude does an amazing job but his bud looks so bad..other grows I've seen growing autos, and yes I've seen autos hit 10-11 ft and yielding at least a pound in the outdoor suburbs but end product quality prove to stray away from em /maybe Grower error.

The video is called
"improving plant root structure Dr. Carl whitcomb give full lecture"

Its a little dry and long but packed with tidbits

I agree on the looks of the buds

But props none the less to growing an auto that BIG i surely have never seen anyone do it.

Also its not just letting the roots grow from the sides so much as it is building a huge store of roots

Which when allowed to be free should explode
With roots dr whitcombs example pics are crazy!

Mabey you just didnt let the roots build up enough first?

Thanks for the replies

I agree it works but I don't think the maximum restriction is a 4 inch pot. How can that single size be true for every tree let alone plant?.

Whatch the video he can explain better than me as im not a botanist.

I think it has to do with hormonal changes that happens to the tap root after it exceeds 4 inches.

Basically if you kill the main tap root it sends replacement TAP style roots
By confining it you turn the tap root off and engage lateral roots.

Like i said im not a dr. Nor phd nor botanist nor farmer. So i might be expaining it badly ; )

Basically you want to train the root to grow horizontal in that first 4 inches

Im sure the same result could happen with a 6 inch cube .

But im sticking to the guy that has done thousand of hours :)

Yeah I seen the vid, warrants a side by side though. The diff between a 4 inch to 6 inch pot is minute, I don't doubt the concept (yet) but still struggle to accept 4 inch pot = the only magic volume. Seems more convenient for him to pick a ball park size and make/sell pots at that.

I've also seen vids on tap roots that basically say if they get root bound you limit root mass a lot even if you up pot. I think the general concept is to A: not use a small pot initially (4 inch+ if he's right) and B: not to let the tap root get root bound via air prune pots.

Typically a plant being root bound is a bad thing root starvation and deprivation. A plant being root bound will starve the roots and stress the plants which could reduce the potency and quality of the plant.

Has anyone ever seen a pot plant get root bound? I'm sure it can happen

As far as mj goes I think it's uncommon in practice. Most newb growers can't get a good enough root system to risk bounding while experienced growers have the correct pot size or style to accommodate.

I trim off any long roots at each re-potting to force them to branch out and fill the pot from top to bottom with lots of fine feeder roots. Even when moving them from little starter cups I just snip off the bottom of the root ball with sccisors or with bigger pots use a bread knife to saw the bottom off and even shave down the sides to get rid of any stringy roots.

Roots branch out just like the top portion of the plant does when it gets topped.

@Dr.Who
@Odin* @Kingrow1 @Flowki @OldMedUser

Im not SAYING ANYONE OR MYSELF IS RIGHT

BUT IM WAITING......... FOR REASERCH STUDIES. THAT SHOW THIS WOULD BE BAD............

unfortunately i will keep on with my experiments

Till someone comes here with more then forum talk :)
@budman111 would like to hear your side of the story as well sir

Till then its about as worthless as a untopped marijuna plant in the wild (doubt its good).

But please prove me wrong as im here to learn not bicker

Peace

Youll just make the same amount of surface area of root hairs wether you prune or not.

Air pots might fill the volume of soil more efficiently but they dont increase yeilds over normal pots.

The main idea was so you could have bigger plants in smaller pots thus increading floor space for more plants.

Yer airpots and root pruning works a treat but dont be thinking they increase biological efficiency.

You keep refering to air pots!

Who the hells talking about air pots!

Im going to be building the base roots to go into
A rdwc and a meniscus membrane flood and drain table. ......

Still obviously you didnt do any research on what IM talking about :(

Still no proof to make me stop unfortunately
But i appreciate the responses.

Im not trying to be argumentative but please post something with a backbone that i can look up.

Your OPPINON of an air pots preformance is MOOT unless you have done the aforementioned root BUILDING IN THE FIRST STAGES OF LIFE .

Again these are not going in an AIRPOT!

The rest is just oppinon and heresay

Simple answer is yes it works but no it dosent make a difference, if thats too complicated refer to my above post on biological efficiency.

Most likely your struggling to root a rockwool cube is all :-)

Well the way i see it should be easy heres a root ball at about 4 weeks since it left the cloner i use kelp and humic thats why my roots are dark

20180113_152842.jpg

So after i transer a plant that i build the roots up
I will take another pic @ 4 weeks :) should be clear as day and have SOMETHING to show
