due respect where deserved, I was seconding sencha on the call to transplant If you have room shoot for 2-4 gallon container if you have time to veg. 1--2 gall if you are itching to start photoperiod (flowering via 12/12)

definitely time to think about transplanting, you will probably find that the roots are beginning to circle. Chances are some new healthy soil in a bigger pot will right any mineral/nutrient deficiencies that are ACTUALLY happening, if they are. If it stops or only happens to those older leaves...

Just stick in a glass of water. Depending on the temp and state of mother plant it will root in 3-6 days. I even uprooted a abused tomato plant, came back the next day, and broke a branch--right to water. Within 2 hours the branch looked more healthy than the plant had before I uprooted it. No...

Put frozen milk gallon (filled with water not milk please!) or pop bottles either in/near the intake or in/near the output. If you are venting into the room you are drawing from, you effectively have 0 cold air intake = big no no for "cooling" you need a heat sink in absence of CAI. Hell even...

from your earlier post: Where did you source the "Sunsource"? can't find it anywhere I've looked so far... not trolling just want to price it out and maybe try it : )

Yea though not the longest cure, I have another run in cool treatment that will have been cured longer. Apparently that depends on your strain/setup because I, like stump, report no decrease in potency in the seeded (trich forest ftw) granted the effect is altered as I let it run longer to...

Yea no %@##$% I saw a reading from them that had a negative delta-9 reading. So you are telling me the ganj absorbs the delta-9 already in your system and blinks it out of existence just to round up your flawed analytics? nice fail

got the same on a batch of seeds too, not on another. different cultivars tho. And yes the black/striped (the substance can be easily scraped off) beans are rock-hard so I would be inclined to think they are mature. also having issues germing that run even (0:25) after 30 day dry +10 day ~34F...

Heh I meant to specify that I was asking 'bout the HPS bulb spectrum, appreciate the disclosure of the t5s. Yea I hear the VHOs actually last longer on a HO setup because of the higher quality electrodes/caps---expecting to basically be overdriven. Provides even more spectrum variation...

Excited to watch, esp with a PAR vs 1kW. Any details of the spectrum of the bulb, sorry if I missed you sayin it already. I hear you on the TGA germination, have gotten 10:10 on a few tries. Frustrating tho, I just saved my first seed from a querk/plush cross and none of the seeds are...

This is one of my favorite UV studies (peppermint): http://www.sciencedirect.com/science/article/pii/S1011134410001107 and if you really want to get into it: http://www.sciencedirect.com/science/article/pii/S0031942210002943 Not as relevant but we do see a lot of N deficiencies in flower...

rock on, best of luck. For the curious, are you doing an organic soil mix a la subcool's supersoil or are you feeding organic store-bought bottled nutes etc? or both?

Light, by definition, is a form of electromagnetic radiation (consisting of an electric and a magnetic field, 90 degrees off axis from one another, and perfectly in phase) from this was drawn my observation. What are your thoughts on the concept of a mag field reducing heavy blue light damage on...

Great work over here PSUAGRO, keep it up!

My personal advice: Find hairy strains, I believe I've found a link. Most strains prefer a 6hr "midday" UVb application, but the hairy ones can take a full 12 hours and um...its basically pron-o-graphic. My thoughts exactly. We are all learning together here, glad I can contribute as I'm not...

also, chlorophyl fluorescence graph: the right hand is emission, the left peaks are their absorption, if you have ever done fluorescent spectroscopy then you know what this means. The pigments emit the righthand peaks when subjected to the lefthand peaks. Fluorescence, not reflection...

green spectrum reflects deepest into the leaf, less absorption and secondary quenching, more passing to other chloroplasts, leaves via chlorophyl fluorescence spectrum (and mainly as the most reflected light in the canopy) Hey, what color is burning Na (sodium) btw? that help? I assume the...

Ill look it over but ill give ya this, I've been doing organic food farming for over a decade, and if BT v. i was good for thrips it would be widely reported b/c it is a wide distribution pest and a heavily used/marketed bacterial larvicide. I use dunks as a preventative for gnats and still...

dunks are bacillis thuringensis v. israel (sp?) good vs. fungus gnats. u want spinosad & neem/extract... I actually mix neem oil & azamax to get the extra goodies in the crude oil. repeat spin every 3 weeks sorry to repeat me PM info just figrd others would benefit (azamax/neem soil drench...

according to djshorts, blue (cobalt) glass may be worth looking into
