Can you pick a high yielder in veg?

[SilentFeet]

Just wondering if you can pick a plant that's going to yield high while it'still in veg?

I think the thickness of the new branches after you have topped it can be a good indication.

I have some Critical Mass and after topping it the next branches that have grown up are quite thick.

Whereas I have some 707 Truthband x Black Widow which have relatively thinner branches compared to the Critical Mass, although the Critical Mass were planted a bit earlier.

Is this a good criteria for picking a high yielder?

No not really. i have thinner stemmed plants that do way better yield wise but do need staking cause the buds get to heavy for branches than i got a super thick stemmed strain that completely larfs out lol.

Plant training i find is one of the key components. my thinner stemmed strain i was explaining yields well has nice spacing between nodes and not too much leaf so i feel the plant gets a lot of light exposure from top to bottom which contributes to yield.

No

Well yea Critical Mass is going to yield, if you're running MNS version for sure

Let the medium dry (coco coir, etc...), check the root mass density (whole thing) in expecting this kind of view :


By this way you will increase a lot your chances to find a yielder "blindly".

@Fuel I take notes about root development when I xplant. They get numbered based on vigor, but roots are important because they smaller roots drink less and usually slow down sooner. Some times these plants have better structure or bigger top colas, but yield less over all.

It's hard for me to determine a "good shape "of roots, because i have numerous ones in the seed stash. Tall sativa and haze with roots like rat's tails, somes califo wich produce only numerous thin roots like plush ...

But the root density is very important to me when i juggle with yielders and the root inspection in the vegetative stage is my first trigger. By example, I don't will consider a candidate with the same aspect that my pics, but with a "hollow" core wich is poor in roots.

By extension and in general, i want specimens that have a hard "sponge" in the pot, not soil with roots lol, to optimize the productivity of my little space.

About 40 years ago I came across a method for determining the yield potential of a plant in relation to the other plants in the grow.

It was known as the Leaf Index and the value for any particular plant was determined by counting the serations on the middle finger of the fully formed leaf nearest the crown/main tip and multiplying by the number of fingers on the leaf.

eg. a Sativa with 18 serations on the middle finger of a leaf of 9 fingers gives us a figure of 162. An Indica with 10 serations and 5 fingers has a Leaf Index of 50.

Now, the 162 and the 50 figures don't predict the actual yield, but it does establish a ratio between the plants.

Few would disagree with the findings in the above example - they indicate a Sativa grown to maximum potential would out perform an Indica when it comes to yield.

Hope this helps.

Peace

Yeah, sounds a bit too old school.
162 what?

 

[moses wellfleet]

Pheno hunting is one of the great joys in life, to reduce it to a mathematical ratio between serrations and fingers... Face palm!!!

Genetic diversity is a blessing embrace it and enjoy it!

I have a strain that puts off huge stems and branches like a monster. Roots with ease even when you got the rot. It also grows massive root systems and uses 40% more water than other plants.

Yield is very low. Never more than 300g/m^2

In veg you can select for fastness, resin output, aromatic qualities, and branching/canopy structure. Flowers need to be grown to know about yields, bud structure, taste, potency. I've lived by veg selection due to number restrictions and always hit aroma, filling space fast, and high resin output.

No not really. i have thinner stemmed plants that do way better yield wise but do need staking cause the buds get to heavy for branches than i got a super thick stemmed strain that completely larfs out lol.

Best advice I have heard, "you must grow it to know it."

What is this I don't even...

I can't. I couldn't. Next level stuff.

As others have said you have to go through the wholes cycle and probably more then once. Quantity is important to commercial growers but quality of the product is even more important. The other thing is different breeds and phenos may react differently to nutrient schedules, light intensities and training techniques. It's a long process but once you get the right one you clone that plant, keep a few mothers and pass around a few clones so if you lose yours you hopefully have a friend that you can get it back from.

It's pretty simple. And I don't see the relevance of how old the knowledge is except to indicate how reliable it is.



The index for the leaf above is 15 serrations on middle finger multiplied by 7 fingers for a total of 115.



The index for the second leaf is 16 serrations on middle finger multiplied by 9 fingers for a total of 144.

According to the method, the plant with leaf #1 will yield less than the plant with leaf #2.

The index for the leaf above is 12 serrations on middle finger multiplied by 7 fingers for a total of 84.

Edited: total for leaf #1 in original post was incorrect.

Who said otherwise? Not me.

The question was: can you pick a high yielder in veg?

Well, the answer is, that you can. The Leaf Index method allows a comparison between two individual plants - the plant with the higher index will yield more, it's that simple.

interesting...

interesting...

The Leaf Index has always held true for me. Prove it wrong and I'll ditch it.

I didn't just pluck it out of thin air like some would on this thread would appear to think.
