Anyone here familiar with phytochrome manipulation. Supposedly far red light can allow you +2 hours lights on and 10% more dli without messing up flowering so you get more weight out of plants. Anyone familiar with this would enjoy peoples input and knowledge on this. Especially Umbra if he's got anything on this.

PJ could chime in on this

http://hortsci.ashspublications.org/content/44/2/231.full

Also Found this

Phytochrome is a photoreceptor, a pigment that plants, and some bacteria and fungi, use to detect light. It is sensitive to light in the red and far-red region of the visible spectrum. Many flowering plants use it to regulate the time of flowering based on the length of day and night (photoperiodism) and to set circadian rhythms. It also regulates other responses including the germination of seeds (photoblasty), elongation of seedlings, the size, shape and number of leaves, the synthesis of chlorophyll, and the straightening of the epicotyl or hypocotyl hook of dicot seedlings. It is found in the leaves of most plants.

Biochemically, phytochrome is a protein with a bilin chromophore.

Phytochrome has been found in most plants including all higher plants; very similar molecules have been found in several bacteria. A fragment of a bacterial phytochrome now has a solved three-dimensional protein structure.

Other plant photoreceptors include cryptochromes, phototropins, and UVR8, which are sensitive to light in the blue and ultra-violet regions of the spectrum.

So there is pr and prf. Not sure what they are but the 5minutes of the far red can change one to the other making the plant think the night was actually longer. It is also called Emmerson Effect. These red lights I see range from 50-150$ and I'm interested in it myself. Seems cool. Also there are things blues do and can also be triggered with a large pulse or perhaps few minutes of use.

yes I have played with all of these. I started using HeNe lasers at 632nm, but it wasn't far enough in the spectrum, so I used Nd:YAG at 1064nm ( near IR ). For the blue pulse I used the Nd:YAG 3rd harmonic at 355 nm. It doesn't make enough difference to get too excited about. While all of this makes for interesting reading, it doesn't make a poor grower into a good 1. It doesn't take a genetically inferior strain and make it double its output. The whole point to growing is to give the plant everything it needs, the other types of manipulation that you are talking about are more for going beyond genetic barriers and imo are not worth the extra work. I have way too many plants to deal with...because a good grow keeps me so busy I don't have time to play with it anymore.

Thanks umbra was enough for me to loose interest. If you would have come out and said yes you can use far red for 5mins at lights out and this will allow you to flower 2 more hours a day id of been Interested. I just came across this and thought I see if anyone has researched or had experience with this. It still seems cool but out of my league��

If there was any value in it, NorCalHal or Aluminum Monster would be doing it. There are all kinds of ways to manipulate plants, most are not specific to cannabis, but may or may not work. For most commercial growers, if there is not a direct cause and effect relationship that translates into a bigger yield, a shorter flowering time, or frostier buds, then you will not see them using it.
1 of the best things to learn is how to open the stomata to increase the plants ability to increase CO2 intake.

I love your enthusiasm glp, but you have to learn to walk before you can run. I think you will get a much better reward from getting the basics dialed in First. There will be time for cutting edge lights, nutrients, and plant manipulation techniques later. I see way too many growers trying to do things like add CO2 before they even have the basic skills down. jmo

I agree with you guys 100%. I'm just insatiable reader. Thank you Umbra. I am sure it will take a minute to get house ac RH leaf temp and tent temp, fan speed etc In balance.

That is one of my problem with your nute line.....if it is organic, why do you need to pH it?

With all due respect I don't care. Its cleanest line out there. If you don't like it I don't give a crap. Quit trolling me. If you want to know anything about ask the owner. They have contact information. Obviously I'm shity middleman for information, go get it from the horses mouth.

Sounds like every other promo video . Better, bigger ,more ,stronger ,healthier. There is no magic nute line. So stop focussing on any thing that a sales person / sales pitch video says and listen to the folks round here trying to offer you help.

K.I.S.S
Keep it simple stupid

Just my .02 .I'm outty.

I don't care about bigger better etc. Its a clean nutrient line. Period I'd rather not use salts and I like idea of highly active soil life.

If you want an active soil life you don't need a product line. Maybe you outta take a look at some organic growers journals. most good ones don't use product lines... I don't know one that ph's either... no fancy gadgets... hmmmmmmmmm

Highly active soil life wouldn't require you to PH anything if it was truly Organic.

You forgot AEM.

How do you know it's a clean line? Because they told you it was?

Ocean salt/water contains over 80000 different microbes.

I am beginning to think you like failure. We all have tried to help you complete a successful grow, but you just do not want to heed our advice. Which is ok, as I will still be sitting back smoking big buds, while you continue to fail. Your failures and posts are becoming quite amusing.:aok::bong:

Well, everyone using this line is using lots of ewc teas labs etc. Also slf-100 it is 4 unique bacteria to the industry. All good. I am going to try the line again. If not good this go ill be using the buildasoil.com approach.
