More plants same light = more yield?

Hello

My grow space:

10 x 10

Blue Dream , my best mother pheno.
3 gallon coco coir drip irrigation.
Either 4 1k DE fixtures or same amount of light in DIY COB.

So my question is this;

Would having 16 plants per 5 x 5 space for a total of 64 plants under ideal SCROG conditions yield more than 9 plants per 5 x 5 for a total of 32 plants with 3 gallon smart pots in coco coir under ideal conditions and drip irrigation?

I have done SOG and from that experience tells me that yes more plants under ideal conditions would yield more.

I generally have many plants in my personal grow and yield very well.

My though is a 10 x 10 is 100/sqf and my 3 gallon pots are 12" plus the saucers under them for water are 14" so per plant is 14".

10' x 12 = 120" .
120" / 14" is about 8.5 so round to about 8 to account for space.

So 8 x 8 = 64 plants.
With reasonable space and drip irrigation.

From my experience it seems like the more plants under ideal scrog would far out yield half under same light with high ppfd.

One lst thing to add would be veg time is 30days, but this is generally applied to all parts regardless of veg time. More plants under ideal conditions = more yield with correct lighting.

Right now I run a personal 3 x 3 coco with 9 plants averaging just over 5 oz a plant under 400w. Just upgraded to LED and want to see how much I can up my yield before going into this endeavour.

I would like real world experience not just guesses.

Regards Trippy

Unfortunately with experience comes the knowledge that predicting yields is impossible,

If we expect completely ideal conditions the results also means nothing because that's never going to represent actual conditions / yields which is what matters.

The best result you will have for predicting your yields is writing down how much you're yielding each harvest and repeat your growing process the same way each time then average out your yields.

All that aside this would be my guess to the answer to your question

multiple smaller plants would theoretically yield more

- Spreading out the multiple little plants mitigates the risk, if you stunt the growth of one plant it represents a much smaller percentage 1/64 instead of 1/16
-You can develop a larger over all root system faster since you have 64 tap roots spreading out
-All of that being said, that's a lot more plants to water / feed / tie down / repot / take care of ect.

I am well aware the yields are difficult to predict, but I was not asking for a number. 8lbs was an estimate based upon previous grows as well as light used (DE or cobs).

I am glad you posted and this did help me confirm my analysis.

I am not concerned with the work or the nutrients or maintaining the scrog as the point is maximum quality product for medical patients.

That aside, seems many smaller plants in idea conditions would be best.

As for stunting, I have this strain and phenol dialled in and know how she like it.
As for nutrients I use powdered fertilizer as liquid is just a waste in my opinion.

Anyways, thanks for adding to the post.

Is a scrogg needed for that many plants? With that many plants why train like that? Would seem to me that all one would need to do is top in veg, veg out for 4 mains and flower out. Then use some method of plant support so those heavy high yielding blue dreams don't fall over from bud flop.

That is also true, but scrog will increase yield more than topping only and even more so with BD. Main point of this commercial grow is to increase yield and potency for medical patients. Plus I would much prefer many AAA Tops than just A buds lower than middle.

Yeah dude, 16 per light can be treated more towards a SOG in my opinion. In a SCROG, you're trying to make that same solid canopy but with much fewer plants. When I'm rockin 16 per, I use a trellis, without weaving/training branches like you would do with a scrog. Never needed to. I mean, i'll pull a branch to where it needs to be here and there but.
i do just as good with 16 per light as I do with as few as 4. But naturally the 4 per light plants need vegged for way longer;-)
16 per light equals way to many plants for my setups nowadays for this guy, so I only do it in a couple trays only.

if you can have a high number then throw the extra plants in and you get what you get . if they are in the corner not direct light they will produce but possible @ 1/4 usual

Understandable. Will consider that

There will be plenty of light. Will be using DE or the new Fluence SpyderX Plus Lights.

Light isnt a concern.

You will get the most yield out of a sog and cramming as many of them as you can in there with heavy pruning(most important part. If you screw this up you will be hurting) so they don't bush out.

However it is more work and if you're not in a legal state the plant count numbers could get you in trouble.

I dont run SOG anymore. Hundreds of small plants is just too much work on return.

Running 64 SCROG under 4k Gavita in a 10 x 10 is my plan or under the new SpyderX LED by Fluence ( New BML)

I am in Canada not US and our legal situation is currently up in the air.
Out west is where the more leanient is.

100 watts per plant is a good rule of thumb once you go over that it's diminishing returns, more pots to run, more irrigation and maintenance.

I think fewer large plants would out yield multiple small plants for one grow. Using smaller plants with less veg time would allow you to get an extra harvest over the course of a year.

100w per plant.. does not add up. I have run SOG and I had no where near 100w per plant.
Watts is not a good measurement for plants. PAR however is

I am not talking SOG here.

My veg time will be 30 days.

growing larger plants will reduce harvests.

I will have c02 as well so growth should not be an issue.

if you ask me its all the same huge plants or very small plants . its farming . you harvest a lot of small beans or a huge one the weight is the same as long as you light is over the plants . its all personal preference and legal # and experience how fast you need to crop . if in a super hurry then many small ones hardly any veg and flower asap . what ever suites the farmer is best .

How about 10 x 400's !!!!!! Id see that working very well for you.
