So when I get it all set up I am gonna have five hlg 260 2x white and 3x RSPEC. I just ordered 2x 30w qb52 strips that are in 730nm. I understand that to get the most from the EE that you have to control the 730nm independently. What is it you actually do to set it up? Leave it on 15 mins after lights out correct? Do I have them come on 15 mins before lights on? Do I need independent control over the 660nm? That is something I worried over after getting the rspecs.
Am I missing anything? Gonna have them in a 4×8 spaced rspec/white/rspec/white/rspec with the a 30w qb52 730nm strips kinda centered in each 4×4 of the 4×8. The qb52s are the same length as the hlg 260 so I thought they would work best to cover the area. Will the 30w strips be enough coverage in a 4×4 for EE or will I have an area in the center of my 4×8 that isn’t reaching full EE?
It was the closest I could get to a 2:1 ratio of reds and far reds to do it this way I believe it was 216 deep red and 104 far red only the deep red are on the rspec boards. Sorry for all the questions guys just trying to get all my bases covered and get everything I need for when I get the new stuff.
Emerson effect is induced during lights on, speeds up growth. Flower initiation effect is induced after lights off. Helps plants go to sleep faster and allows you to run lights burning flower on 13/11 schedule to get extra photons on the plants. If this is not needed due to all the photons you already got blasting them it can help with better genetic expression of flowers and reduce flowering time when running the standard 12/12. Should be plenty of watts and coverage. Where did you find the 730nm bars if you don’t mind me asking? Also turning them on in the morning is not necessary or useful as the morning spectrum is slightly more red and not far red.
Thank you for explaining that. I knew that EE was something I wanted to shoot for but wasn’t totally sure I got everything I needed. Being able to speed flowering and enable better genetic expression is a win win to me. I looked all over trying to find something comparable to the qb52 strips in America but all I was able to find were the rapid pucks which didn’t have the wattage I needed and some qb11 strips on ebay but nothing in all 730nm most were mixed emerson effect boards. So I ordered them from China, Shenzhen Kingbrite to be exact. They are the only company I know of right now producing them, although shipping is slowed because of the virus and pretty pricey being almost as much as the product on the qb52 boards with meanwell drivers.
So just to be clear my 730nm boards will come on at the same time in the morning as the other lights and then stay on 15 minutes later.. That way I am getting photosytems 1 and 2 running at the same time. I wasn’t able to find a ton of info on it actually. There are some lectures on the emerson effect but finding which one I need to watch has been problematic. I seen while browsing some of the newer lights are adding 730 and 660 together but they put it on a switch so you would have to manually go in there and switch it on an off but I dont see how you could use that for flower initiation unless you can light it up without the main light. Seems like a flawed design from the start to me.
Yea some drivers have the ability to control lights with a controller but the switch would just be too reduce your red spectrum in veg. If your experiencing large internodal spacing then you could reduce the red in the spectrum. Running the 730nm with the lights on will allow the phytochrome state to switch back and forth rapidly allowing for a higher efficiency in growth. 730nm while lights on to induce emerson effect. 730nm for 10-15 mins after lights off to induce the flower initiation effect.
I have dimmers on mine but there aren’t any switches that turn the different colors on and off. I was talking about some I had seen just browsing. I generally only veg with them long enough to get the plants used to the spectrum. I got them for pretty much flowering only. I have an old blurple that is a boss at vegging lol also I dont have a lot of room for veg.
That is just what I needed to to know about the 730nm confirms what I had been thinking from different things I have heard. This whole emerson effect things seems to be somewhat new as I haven’t found a whole lotta vids on it. That being said I haven’t browsed the forums much I am sure plenty of people are using it. It would be awesome if they would do a patreon or just a episode about the EE. Like you mentioned its switching back and forth rapidly, is that happening all the time while lights are on or just morning and night. Man I would love to go back to school and get a horticultural degree. I have loved growing things since I was a little kid helping my grandpa in the garden. Plants are a real joy in my life and learning stuff about them and how to do neat tricks like that is so much of the fun. I would have never even though about attempting to set something like that up had it not been for the help here and the show letting me know it existed in the first place.
Thanks for the info about the internodal spacing too.. I am always letting my plants get way to big. Do I wanna keep these type of lights right down on the plants or a good ways above them? Also, what should my lst be. I used my lazer and it was 71 earlier but I have kinda been just letting them slowly grow in the high 60s tempwise to help me eradicate the spidermites.. The strain I am playing with now is way more susceptible than the last.
Check this guy out. It is a longer video but between 5 mins and 8 mins he is talking similar factors to what you explained your going to use. Cool idea I’d be interested to see how it turns out https://youtu.be/sS7aAcacfgk
That is pretty interesting. Def a noticeable increase by adding the far reds.
