The idea that cannabis only has one phytochrome was from an AskEd column from Ed Rosenthal on CannabisCulture.com in September 2005. He detailed the effects of red/infrared light and it's effects on phytochrome. It's what originally prompted my question of raising temperatures at night. I'm in...

In fact, it does have a multi-tap design. At least, from what I understand of the context of the sentence. It has voltage wires for 120/ a couple I don't remember/220/240/277. It's a magnetic ballast, if I'm not mistaken. Copper wired wrapped around to make a superconductor? All the other wires...

I'm wondering where that chart came from. It is a basic truth, but far from complete. Different wavelengths within a light spectrum actually trigger different metabolic pathways. I studied this last semester. I'm pre-med majoring in Clinical Lab Sciences. Each chlorophyll has many molucules...

hey fdd, could you help? It's a questionI posted in the Advanced Grow forum. check it out https://www.rollitup.org/advanced-marijuana-cultivation/40388-phytochrome-infrared-interaction.html we've bounced som good ideas, but your expertise would be awesome. good on you for donating!

to fdd2blk: I would just like to say that 14,906 posts is very credible. Could I get a round of applause for such dedication? If I had people like him in my home town, I could get a NORML chapter started in a month. Anybody from Edmond, Oklahoma? That's right, I just gave out my home city...

Must see pics! I am a very happy soil gardener, but am changing to hydropnics soon. Did you guys hear about a florida bust? It was up on NORML, an entire house was used, 171 plants estimated at $200,000 street price. If it was schwag, that is. Which isn't likely, a set up like that, when it's...

To Tahoe: The example in sweden was for vegetative. I know that cannabis does require a night period of a specific ratio to it's light period, the 11 hour is not a rule, but a good principle based on a 24 hour circadian cycle. With that in mind, would infra red manipulation encourage shorter...

It's an excellent idea, I like the IR bulb, but that would be difficult to measure temperature increase. One thing to do is to pay loads of money to have an ultra-sensitive thermostat... there's gotta be a good way to mark and watch it... Standard space heaters are also not very accurate within...

Ok, I figured it out. It was a voltage application. US households run on 120 volts, while the ballast was originally hooked directly to a box drawing 277. If I splice the 120 volt wire, it should work when I plug it into the wall.

Oh, and lastly, for the record. Dispersing the 6 hours will cause photoperiod disruptive disorder. IT WILL CAUSE HERMAPHRODITES! DON'T DO IT! I have a personal book which I have collected call Don't Be Stupid. It chronicles every time I killed a plant because i did something stupid, like turn...

SgtPeppr, To answer why a higher temperature might work is this: Infra-red light is beyond the human visible spectrum, but not a plants. All energy is in wavelengths, even light energy which is considered a photon, both a particle and a wavelength simoultaneously. What plants "see" as far-red...

When you topped the plant, did you cut at a 45 degree angle? Often, when pinching the or cutting clones off the scion, you can get an air bubble inside the top that travels down the stem. Is this "nube" part of new growth? If it's just developed on the area right below the pinch and travels...

Infrared light converts the form of phytochrome from PFR to PR, with critical levels of PR triggering the hormone tentatively called florigen. Would a slightly higher temperature level at night increase to conversion of PFR to PR during flowering? If so, what is my margin of error? The last...

They are almost guaranteed to be stunted in early growth. This is only partially recoverable by eliminating limiting factors, give it plenty or CO2, water, nutrients, ventilation, oxygen, and they will survive. Also, depending on how much water they absorbed to instigate the germinating process...

Earth Juice is incredibly effective nutes, a favorite among hydro growers. I am a soil grower. I overfertilized on my first crop. I used A soil compost with an artificial slow release, cow manure, ground kelp, and the diluted urine of yours truly, using gypsum to adjust for pH. Urine should be...

Actually, homerbud, plants don't need any sleep. Originally it was believed some dark period was beneficial, however Ed Rosenthal and Jorge Cervantes both tell us that studies have shown a constant light cycle kicks the plant off to a faster and more vigorous growth than allowing a dark period...

post some pics? It's hard to tell by a description of "nube" but it easily could just be a deformity. Often, when a plant is damaged, it'll kill the cells of the damaged area and build a "scar", or just thick tissue around the affected area, and redirect its growth. You see this effect with...

Hey, willie, I like that idea. My mother and father are both conservative Christians, but my brother and my sister and i all smoke pot. My next professional harvest is a uniquely selected strand by each of my siblings and myself. I can't wait until they see the finished crop, they've never seen...

Purple #1 is a longstanding favorite of mine. Very intense high, myself and 3 other heavy smokers got blitzed off a half a gram. It was a dark purple color and the smell was erotic. Here's a question, is Purple Haze and Purple #1 the same strain? I've heard conflicting stories, but the bud looks...

mockingbird's telling the truth. Marijuana is on the black market only because of unfair enslavement laws, but that doesn't mean potheads and grower's are criminals. We are law abiding, tax paying, dope-fiend fearing, citizens. It's part of our duty as members of our community to report any...
