LED lights

[Mistaya 21]

Hello all 

I grow with leds lights. 

I lst and scrog as well 

what I would like to know is how far do you have your lights away from your plants when in flowering 

the reason I ask this is because I only got 15 oz off 6 plants and I had 3 x 1500 watt leds 

i had my lights set at 18 inches above my plants. 

all my plants were healthy

It all depends on the temperature you want  and the temperature you want to canopy. By return to that you must raise or lower your lamp

 

So, if you want 27 ° C in bloom, you put your light at the exact distance to have 27 at the canopy of your plants ;-)

Theory is the theory: 60cm for 600w 40 cm for 400w.....

But in practice it depends on your space, environment, setup etc ...

 

Have a nice evening dude

This good picture on another thread that may help:

 

 

Perhaps yours were 6 inches too close? (based on the above chart saying 24'')

 

On looking at your buds, at the time I thought [16/1]"It looks early to me. Still fluffy with the buds not joined up yet", but figured you knew your plants and how you like your trichomes.

Also, you harvested two of them very early as far as I can tell one in week 6 and one in week 7 (if I've worked out your flowering start date was 22nd November, based on when you stated you started week 6, etc).

That's all I can think of, and it may not any of those and merely for further research.

It was the 17th of November I went on to 12/12

All my buds were cloudy and my trichs were about 10 to 15 % Amber

This is how I would (and have in my grow, not saying it's right) work it out:

17/12/2018 start of transition (switch lights to 12/12)
Around 2 weeks of transition from veg to flower

01/12/2017 first flowers appear, so day 1 of flower

(add a week per heavy defoliation to a 9-10 week flower period [8 weeks for perfect conditions but we don't have them)

So, 10-11 (70-77) weeks (days)of flower mean harvest ~ 9-16/February.

you can run a little less temp if you can maintain a lovely root temp,  am sure there was a study some where, ed rosen blah blah.

15 oz of 3* 1500 wat led so max = 4500 watts.

interesting these figure don't sound correct why so low yield,  there must be other factors.

does not sound great.

 

but if the gear that you harvested was really cool who cares? as long as you happy right?

It’s a really nice smoke 

I went by what It said on the instructions said. 

Next time I will have them at 24 inches

using viparspectra  450w at my latest growing project, i just followed the recommended heights provided by the manufacturer. i am talking about the graph posted by shaggygrower.
