T5 HO Vs Natural Light (Documented Results )

[Cabron]

I have outside in MI a secure enclosure for my licensed Plants
Overhead is a Greenhouse Shade Netting cover color Black
The Mi sun has been incredible this year with barely any rain
we are in drought conditions.

Test subjects East Coast Sour Diesel S1's

Media in all subjects and nutrients the same

Photoperiod for T5 indoor 20/4 On /off
Target Plant was removed and placed indoors for 5 days
under a Brand new T5 Hydro Farm Designer series Fixture
running stock Agrobright 54 watt 6400 K bulbs .

Target plant was then placed back outside amongst it's
siblings for comparison .


I would like to note that this plant was the same size and
appearance as the others when I removed it initially .

It displayed no jump or head start in stamina or vigor ...


I feel this speaks clearly for the efficiency of valuable
usable spectrum in T5 lighting when compared to the UV
damage that the natural sun delivers .


The plants outside are clearly remaining a lighter shade of
green to protect themselves from over exposure and the
growth has been inhibited due to this applied stress...


Conclusion ......Indoors T5 lighting clearly is the winner in
this contest ...


If T5 lighting only had the capacity to deliver the spectrum it delivers with the amplitude of the sun it would create Flowers
the size of Texas....

 

[Cabron]

I'm sure you will figure out which is the Target plant

but for the slower individuals .....

 

[Cabron]

If these seedlings were treated to T5 lighting since germination
I'd betcha a case of Sam Adams they would be 60% larger than they
are currently and lush green ...

 

[supermanlives]

well ya the ones inside get full lighting for 20 hours

 

[GP73LPC]

right, why not give the indoor plant the same lighting schedule...

you got more plants go for it.

that would be a more legit test...

 

[junior_grower]

man really that's a side by side to you? Extra hours of light? two different environments?

 

[Cabron]

wow you guys are a tough crowd ...
Pretty simple look at it this way

the dates for the 5 days have 15 hrs daylight
so thats a difference of 5 hrs x 5 so say 24 hrs

do you feel that all the others outside are going to look
like the target plant in 1.5 days time ?

Two different environments ...yeah thats the point
indoors under a T5 compared to outdoors under mother
nature...

I feel it's quite a difference in a small timeframe

At least worth sharing ....

 

[Cabron]

Tomorrow I'll adjust the inside T5 hrs to 15 and jerk two more and
bring em in for 5 days .

 

[sso]

hmm, it depends on the outside environment.

and on the plant.

is it indigenous to your area? it would probably grow better outside than inside, if it was.

i f.e cant grow some plants here outside, simply because of how dry the air is. and those that do grow, do so slower and become much smaller, while plants suited to this climate become much bigger.

and there are many other factors beside humidity at work.

but, often inside plants win out, simply because outside is a bit of crapshoot.

up to a point, there are not as much root restriction on outside plants.

 

[Builtaforest]

norcal doesnt make outdoor look like a crapshoot to me

environment vs environment pretty broad here. we seek to test t5 vs sun, but temp, humidity, airflow, pests are also additional variables in addition. we are running on few true controls. this cant be info for infos sake.

tell us what you're really after cab

Outside is a crapshoot in some climates for sure but areas like Norcal
and even MI in the summer are pretty damn ideal.

Thus the reason I've always had a notion that you simply can't beat the
growth attainable outdoors.

But I will have to admit that My assumption may be flawed
I've always seen that plants under a MH indoors were lush and growth was
superb,with the dark green hues showing fully almost black in some strains.


It's the growth rate that I didn't feel I could compete with an uninhibited
outdoor grow...Now I'm testing this theory ..

With the photo period set aside and climate variables looked upon
I'd say that its been pretty damn hot outside averaging 89 lately
indoors ,ummm no
Indoor environment is about 76 F and 50% RH
The RH outside has been zilch lately ,yeah we are in a serious drought here
it's getting scary ,,,crops are all fukked , lawns are brown as hay .

Plants are pulled and new targets are now under T5 as of this morning .
Guess we will take another look at this ...


As far as LEDs go ....
I appreciate the sales pitch friend but I'm not biting on those yet
maybe in the future ,,but Plasma is where the real advancement will
be along with Ceramic Metal Halide delivered in a 600 and 1 K wattage.


Right now I'm going to play around with some T5 fixtures over my vegging areas
and study them ,,,again with some purchases of various aquarium phosphors...

T5's are great til a the plant gets a little taller then they do not work so well.

Where t5's fail is their penetration. You cannot match the penetration of the sun on a clear day with any fluorescent. The penetration of t5's even fails when compared to HID.

Now some people will say but but but...they use t5's as high bay lighting in warehouses. And yes this is true, and they do throw light very far, but that light is not strong enough to grow plants, but it is plenty strong enough to illuminate an area to see.

Your indoor plants probably grow better at this point because they have a nice even light and schedule, more hours of light per day better environmental factors, even temps etc... and your plants outside may not get full sun all day, some days they weather might not be so good but in the end of their life outdoors will still reign supreme.,

Hello Lion ...Yep I agree with what you are saying
I wouldn't do much more than veg with T5's as I have an option
to use another environment be it outdoors or HIDs

But I do have a few licensed gardens I consult for and they are Vegging massively thick and lush plant under 54watt T5 8 bulbs hoods and it rivals 1k vegging that I've been accustomed to .

So I'm honestly extremely curious about the true potential of T5's as I'm new to their use personally and been a bit skeptical until now.


I removed two more siblings of the ECSD S1 batch from the T5 and made room for the new target plants ...2 of them
and adjusted the Hours to 15 on 9 off ..

I'll do this for only 5 days ....just like before

These are the two removed this morning

 

[Cabron]

outside in my cage

The new target plants are dwarfed by the indoor siblings

 

[Cabron]

Here they are sprayed down with pyrethrins for thrips and nestled in
with their other happy and lush siblings under the T5 ..

Lil shits look meek and wanting compared to their sisters ...

 

[Cabron]

My intention with this thread is only to explore the potential of T5's
I'd rather not see the LED debate in this although discussion is welcomed
just not a pissing match ....
