240 Watts All White LED Grow Northern Lights

As some of you know, I recently picked up an Apllo 8 from Cidly and want to keep a thread up with its updates to show off the importance of white LEDs in a grow and how they can bring about a great yield due to the spectrum involved. My current temp is set up with LED on the left side and HPS on the right and due to th limited space the lights aren't overlapping each other so one side is predominately LEd while the other is predominately HPS. We will see the difference, though not as drastic as if they are in separate tents, it will be there nonetheless.

They were vegged under a MH of 400 watts and I switched them down to 12/12 around the middle of march but I did it gradually so the real switch came about the last week of march.

The LED consists of 4x 2700k, 4x 6000k and 4x 6500k

I added it, thanks for calling out out.

Here is a pic maybe 2 feet from the light, to show the impressive bud forming going on even through the canopy.

Looking good.

So you decided on 8 x cool/neutral white and 4 x warm white on each module. What were the reasons for this ratio?

The reason was for a full spectrum light that would cover all the basis. As for that, sunlight is generally around 6500k so I decided to add that for good veg growth and then the 2700k's for flowering as well so that the lights would be good for both as a full light.

Fair enough. Will be interesting to see how it finishes in flowering as i think it is lacking in the 600nm-660nm.

Please prove me wrong...

Will do!! Keep you posted in this thread then, I added the light in at about 2 weeks flowering so that will give it about 6-8 weeks of just the LED hitting them. So far i'm impressed, trichomes are forming everywhere, now we just see about bud density compared to the HPS next to them.

What angle did you go for on the lenses?

They are each set at 90 degress, enough to get good penetration yet spread the lights out for a mix of color.

Nice.....i'll just shut up now and watch...

Hey, ask away! haha but yeah, I am hoping for good growth to kick in at about 2 or 3 more weeks. She seems to be putting all her energy right now into trichome development and new bud sites, which I am not complaining about one bit.

Interested to see this grow, got some NL babes going myself

Ok i'll ask a couple more...

So they are about 25-30 days? Middle of march you said....Is that right? Good development.

What nutrients are you using for this grow....different to your HPS?

I am using the same nutrients throughout. Each plant is about a week behind each other. Not really sure how that happened, each one seemed to adapt to the lower light each day, I started off at 16 hours veg time and slowly reduced it down to 12/12 over about 2 weeks. My LED plant is looking about 3rd week, though it is hard to tell and one of my HPS plants is about 2nd week, whereas the last HPS plant is barely beginnign to stretch during flowering, I have had to supercrop her everyday because she is extending well past the light. If I continued to let her go, she would have made it to atleast 5 or 6 feet from the looks of it. Never expected that. She literally made a foot long growth spurt yesterday night. i woke up to her being past the light.

As far as nutrients go, I am using Dyna gro bloom and grow, along with a small amount of pro-tekt just for fun. I have been using a 50/50 ratio of grow and bloom to even out N and P to decent levels each. I have been feeding maybe once to twice a week and these girls are taking in water atleast every other day. I haven't been able to go any longer then that except a few times.

I started the switch to 12/12 on March 14 so exactly a month ago and did that by accidentally (not on purpose but worked out well regardless since people recommend it) leaving them in the dark for 12 hours as i switched the schedules and due to someone coming over to check out the house. I then started the descent down to 12/12 until around the last week of march. They showed flowering signals around the first to second week but it was gradual at first instead of onset as direct 12/12 seems to start due to the girls thinking they must flower right now.

Just for fun, this is what i plan on doing for my full LED grow from seed to harvest. Just not sure what strain to start with. I am thinking G 13 and/or laughing Buddha to begin.

hey dude just wanna let you know, the title of this thread is kinda confusing cus theres a company in the uk who rebrand cidly lights and they are called 'grow northern' and your thread is called grow northern lights.

Well noted, good to know. I cant change that now but I will be careful in the future. Atleast I have Northern Lights and not just grow northern. That usually makes it easy to see its a strain not a light company.

Disclaimer: I in no way am affiliated with Grow Northern nor got my apollo from them

Ive grown Barneys Farm Laughing Buddha twice in pretty basic conditions and its a fantastic smoke at the end. Cool stuff going on in here mate, kind of like a mad weed scientist convention.

Thats what i'm aiming for!

I'm watching for sure grower............interested to see the outcome! good luck
