After some puching the leafs down
picture.php

The auto on the left is so small and already showing pistils, 17 days in, 75/80 days harvest advertised, dunno if im on schedule, ahead, or late, what you guys think?

Note to myself, start the next grow with this light configuration but at 45cm from the pots
Peace

You are doing good.
Your seedlings are on time, only with hydroponics they can grow faster.;)

Can you heat a bit more your bigger plants?

PS my samsung sil 12w 1200lm 2700k at 45cm misure 3400lux.
Can you take a misure of your 12w at 45cm?

Edited on day 21 of January
For clarification and no more doubts
The math that i did for the lights was.
I need 25w per sqft with sils.
I use the metric sistem so, 1 sqft = 0.09 sqm
The measurments are 0.3m x 0.6m = 0.18sqm
0.18 x 25 : 0.09 = 50W the ammount i need for my cab.
Im running 54W so
54 : 0.18 x 0.09 = 27w per sqm
Lights at a distance of 30cm +/- from the cannopy
Im in the spot

In the older cab where the bigger girls are
Im running 39w
Measurments 0.35m x 0.55m = 0.19 sqm
0.19 x 25 : 0.09 = 53w sqm
53 : 0.19 x 0.09 = 25w per sqm
On point

I should be running maybe a bit higher because of wall losses but whatever

Sorry for the confusion folks and thanks explosiv
Peace

Sure

Thanks caio:)
This one Philips 13w 1521lm 27k with my Samsung S10 (for what is worth it or not because is not the camera that captures the light) reads about the same as you, between 34k 35k lux.
Yours have more or less diodes than mine?

This worked for me,... 120 Watts of heat.
(The bulbs are 7.55 lumens per Watt. Lol)

Mine count 30 leds.

At 45 cm my phone lux metre misure 3.4 klux or 3400 lux

28.5 klux or 28500 lux At 15 cm

??? Wtf

That sounds about right.

Light intensity is a squared relationship.

It's 3 times closer. 3 squared is 9.

9 X 3,400 is 30,600 Lux.

Yeap caio at least in matters of the closest the strongest if you dont have the cap of the sil on.
Thats one of the reasons that 25w per sqft woth sils is enough for good proper development and flowering.

If you get your meter close as 2cm you will read about 50k+ and thats normal

Mine has 34 diodes.

Keep in mind that blynx and others use lux as a measure because they compared their meters on other grows with hps cfl etc at the time to have a mean of comparision and not to get the proper lux and the reason why i think is because sils are a bit a mix between quantum boards and cobs, not so spread as the quantum and not so intense has the cob do you get what im saying?

Btw i think i manage the temp issue of the older girls, i guetto ducted the other cab to them by underneat .
now im testing to see if it works or not, if it doesnt i will try to intake the air trough the top of the cab because is sealed, lets see.
Peace

Also today i received the watt metter that i bought, hurray AliExpress kkkk
So for everything turned on 624w
Led + vent + controller 116w
With humidifier 15w
Heater of the bigger cab 463w
Heat cable of the smaller cab 25w
Keep in mind the heaters and humidifier are controlled so they are on just for brief minutes
At 0.14€ Kv in 7 hours the cost is of 0.33€ kkkkk
Pretty low, i was scared that the bigger heater would sky rocket the power consumption, im glad it didnt plus i can tweak the environment as my desire
Things are getting good, im a happy man :D

Funny, you use halogen bulbs for heat i use them to stimulate strech kkkkk

No, those are incandescent.

Really old-school. Lol

It's the same technology they had when they invented electricity. Lol








I'm surprised they are still available.
I got them at the dollar store.

So the smaller cab is at 20.6c and going up, looks good so far
If the duct tube was isolated i think it would be better.

I always know halogens by incandescents also, its the same more or less as you posted kkkk

Day 18

Day 18

So day 18 for my Auto blue amnesia

Everything looks fine, the only thing i see strange is the fingers of the bigger leafs being so tight togheter they hurt each other..

And today when i woke up and went to check my girls, one of the sils was in contact with the leafs, it burned it..but only the part where the diodes touched, i removed the most damaged leaf and leave the rest
picture.php


Also the ducting from the other cab to warm this one was a succes, the temps are always 23c +/-, the only downside is the humidity is quite up, between the other cab, the weather and the girls being bigger and sweat more the rh is always between 60/75% need to get an circulation fan and work on it.

Also just for curiosity i went to the philips site and check all the spectrums of the bulbs that i have
picture.php

All of them are 80 cri
I think the best spectrum of them is the 4k one for a seed to harvest grow, what you think guys?
If you were going to buy, wich one would you choose?
Peace

I'd pick the 4k.

The graph has the flatest curve and the white below the curve has the largest area of all the four graphs.

The most amounts of all the colors

Thats exactly what i was thinking, the most amount of everything, i guess that from seed to harvest on the low budget side i would go with the 4k also.

It's almost time to lst the amnesia...:yummy:

2700k make compact buds in floweing and stout plants in veg. Plants reveg and clone faster on a 2700k.
Under this spectrum plants eat more fertilizer and water.
I had only two plants (barneys farm lsd) that after 150+ days of 12/12-10/14 were only starting flowering but i dont know if it was bad genetics or the lights.

Never grow under the 3000k

6500k is the best for veg. Plants are more branchy and with smaller thinner leaves.
I Never flower with leds under this spectrum. Only cfl but they have a different spectrum.

4000k is halfway between 2700k and 6500k.
Is not good in veg as the 65k, is almost the same in flower as the 27k.
Plants are more resistant to stresses.
Clones and reveging is a little bit longer then 27k.
Flowers under the 40k are very similar to the outdoors: big, not so dense and leafy.
Very good general purpose lamp.
Other crops are insanely more happy under this spectrum then the 27k.
And last...i see better the true colors of the plants...under the 27k leaves seems almost yellow, Under the 65k are dark green.
