Help with LED

[gokenzo]

Hey folks. This is my second topic here. I see that all of you are very friendly and giving advices to everyone.

So let me tell you about my problem. I'm not sure if im using my LED light properly. I'm growing critical + indoors female. It been 15 days already after germinating but it looks too small for me compared to other people plants. I'm adding a photo how it looks and the size of it.


I've hanged my LED on 100cm heigh above plant with only VEG leds on. I'm following these instructions but im using 18/6 hour cycle. Can somebody tell me if im doing this correctly? I've never tried to grow with LED lights. And its my first grow of all time.


As you can see my pot is transparent and I can see some roots growing over there. Is it necessary to transplant the plant to another pot that is opaque?

Strain - Critical +
# of Plants - 1
Grow Type - Soil (Biobizz all-mix)
Grow Stage - Young Vegetative
Bucket Size - around 1.5 litre
Lights - Viparspectra LED V450
Nutrients - Didn't use yet, because biobizz allmix has nutrients for first one month(tell me if im wrong)
PPM - Don't know
PH - 6.5-7
RH - Don't know
Room Temperature - 22-23 celcium
Solution Temperature - Like 4-5 celciums lower than room temperature
Room Square Footage - 1.8' x 2.5'
Pests - None Known

I’m a noob too as I’m on my 2nd Grow now. I don’t think you are doing anything wrong really but can maybe move them a bit closer in that 60-80cm range. I’m growing 7 in my 4x4 tent with a HLG Quantum Board and I have one plant (Black Sugar) that is growing but not at the same rate as the 5 others I planted with it or the one I started 4 days after everyone else (Black Domina) It has a few issues too but looks further along that Black Sugar. So it’s probably just the genetics of that seed.

Although the more experience growers might know better than I

that's 40 inches above the plant
I would move it down to 30 inches and check progress in a day
I would also activate both switches based on personal exp with the VS Reflector 600
roots don't like the light, you don't need to re-pot if you can find a dark sleeve to put around the cup

 

[gokenzo]

Allright so. I've found dark sleeve as you said. Looks fine with that. Moved down to 29-30 inches with both switches on. Let's see if it helps. Temperature was around 22-23 celcium, now that should increase up to 28.

I will write results here in couple days. Maybe it will be helpful to other growers.

you don't want temps higher than that

Sound like i need a bigger fresh air intake hole. Now its just 4 inches wide for 3.6x1.8x5.2 feet grow room

 

[Stunned]

put a 195CFM inline fan on it
hopefully it matches your exhaust

 

[gokenzo]

I already have with 92 CFM fan over there. Don't want to buy another one. Wouldn't a bigger hole help?

 

[Stunned]

as long as your temps stay under 28C, you should be ok
what are you using for exhaust?

 

[gokenzo]

that one. 4 inches diameter, connected with aluminium hose to exhaust hole. 92 CFM. will connect carbon filter a bit later(didnt arrive yet)

 

[Stunned]

are you sure it's only 92CFM?
looks suspiciously like the one on Amazon
if it's 4 inch, they usually are all 195CFM

 

[gokenzo]

Well according google 155 cubic meters/hour is 91.229 CFM
technical specification of my fan says it cultivates 155 m3/h

 

[Stunned]

I'v 2 of the Vivosun 4 inch inline fans rated at 195CFM
one on the exhaust and 1 on the fresh air intake
and I have a spare in case one craps out
they are pretty cheap on Amazon
keeps things cool

I use Marshydro 300’s and have them at 24 inches for veg and 19 for flower.its a comparable light. 30 inches seems high to me but I see it is the mfg recommendation.

How big is the space it’s covering?

I’d search posts and diaries to see how others set theirs.

Clear containers are no good for roots. The darker the container the better.

 

[gokenzo]

Well ye, they are not expensive. I paid for this one i have around 40$. I can control temp in every room in my house so temp in growroom shouldn't go higher than 28 celcium.

How big is the space it’s covering?

 

[Sctanley007]

You may have misunderstood. What is the square footage of your growspace?

 

[Stunned]

1.8 x 2.5

Yeh man sorry. I live outside US so English is not my first language. Yeh, my growspace is 1.8x2.5(basically 3.6x1.8 but my light won't be able to cover all this space, so im using like 0.8 feet for ventilator place) or 6 square feet

And i can see the results already. Leaves are pointing hard towards the light, they love it! Temp is around 74F so thats just perfect.
