Will the fans in the LED lights run "backwards" if their polarity is reversed by switching their AC wires? If so, they should discharge the hot air through the top of the housing and allow you to vent them outside of the tent without too much trouble. This might cause some difficulties with the fans lifespan since they would be operating in a hotter environment (i.e. post-LED as opposed to pre-LED).

I probably could, but the issue isn't that enough air is blowing, its that there is no way to evacuate the hot air from the light, directly out of the grow area... Its ok... so far the high temps don't seem to be effecting the plants much, I'm sure it is slowing photosynthesis but they still are healthy and not stressed so I guess I will deal with it...

I've dealt with leaf discoloration but it was on another level. Looked way different and it was to not fully cooked soil.
Wish I new what was up with your leaf but unfortunately I do not.

Also damn your grow looks good bro.

I'm getting ready to put 5 topLED in a 4x4 their 100x3 old model. Wonder what Temps will be?

Anyway KEEP GROWING, STAY HAPPY

Icemud, my comment about the fan's direction of airflow was not ment to increase the volume of air but to provide a reduced number of exhaust locations on each light This would allow you to attach flexable dryer vent to the lights to evacuate the hot air from the tent (probably through the existing air filter). Sorry that I wasn't clear in my previous post.

im always having calmag issues with led now i just add 4 different amendments and calmag/epsom salt/calcium carbonate, every other watering, seems to keep the issues manageable,

Your leaf damage appears to be either from heat stress, light stress or a potassium deficiency cause by nutrient lockout or root damage. I am finding it very easy to control the temperature in my 6'4" L x 6'6" W x 6' H Grow Bay #1 using LED light panels with 975 watt power draw with the Day/Night Temperature Controller controlling the Vortex Inline Fan 6in 452CFM with a Phresh Filter 6in x 24in 550CFM. The Day/Night Temperature Controller can be set at 85° Fahrenheit and my temperature is normally 77° Fahrenheit. I set the Day/Night Temperature Controller to run in the dark phase constantly for air circulation in flower to avoid any humidity buildup in flower during the darkness phase.

You want pH 5.8 for hydroponic and soiless (peat moss and coco coir) and pH 6.5 for soil.

Hey everyone..... update time...

Thanks everyone for the suggestions on the leaf discoloration issues. I believe I corrected it... Since I wasn't quite sure if it was Mg or K defficiency, after flushing all the plants very heavily with R/O water and checking the runoff, I lowered the runoff ppm down to around 1400ppm which from past grows seems to be a good "safe zone".

After flushing I wanted to replenish the nutrients that were lacking so I added epsom salt, general organics cal/mag and potassium silicate to the feeding to address the deficiencies...

I couldn't believe it, the next day, all the leaves were in that upward angled posture, showing that they really enjoyed the flush and supplementation and the plants seemed to be full of life and thriving Sweet!!!

Well its getting close to the flip as the screen is nearly full, and I think that probably by next monday, I will be flipping them to flowering schedule

Wooo Hoo!!

Here are today's photos...Look at the nice High Brix shine to the leaves! beautiful!

Thanks for the suggestions King John. I believe it was due to too high of a soil EC, but have corrected it by flushing all the soil with r/o water, and then followed it up with a light feeding of r/o water, epsom salt, general organics cal/mag, and potassium silicate. (basically the 3 possibilities on the look of the leaves). The day after doing the flush and light feeding, the plants leaf posture was back to normal, reaching for the lights, the leaves developed a lot of new green growth by the petiole, and started bringing back their high brix shine

Not heat stress because no curling "taco" of the leaves. I also noticed some of the tips of the leaves pointed down on a 90 degree angle which signified high soil EC so I am pretty sure the flush got everything back on the right track

Appreciate the suggestions much!

Guess what everyone!!!!!????


Tomorrow will be the first day of flowering!!


Woo Hoo!!!

Here are the photos for day 2 of flowering (sunday).

The leaves are looking great and have restored their high brix shine

The 2 plants on the left and back middle (mystery kush) have very interesting leaves. The edges of the leaves have a puffy ridge along them and is really shiny...almost like the leaves are outlined in high brix shine pretty cool

So the girls definitely know its flowering time and have already begun the stretch The screen is looking great now that it has tops reaching up for the lights everywhere

Today I gave the girls a foliar feeding which I have not done in a while. I decided to give them a feeding of the bubbling mix of R/O water and calmag that I have bubbling, and to it I added carboload, PGR, Bloomit, and cold pressed seaweed. I also added a dash of Spinosad for preventitive measure against any pests that may want to even try..

So far the Intelligent Gro 2 lights have really put on a show, and vegged my girls very well. I now only hope they can perform just as good in flowering and I will be very satisfied and so far things are looking great

Here are the photos for today,

re: Icemud's Intelligent Gro 2 LED Grow With V-Scrog - Going for 1lb & Beyond!

I have a blue dream in veg (mother) under first gen light like yours.
the other day while cleaning walls and stuff I turned on the cob switch for extra light and then forgot to turn off when I finished.
After a 4 day absence I walk in to a growth spurt that would rival a 3 week period of flower stretch.
I am wondering if we are manipulating the light schedule from the right angle.
Outside the sun does the graduale up to full power and back down daily but also over a 6month time frame
And not to long ago we did the same thing with cfl/t5, dimmable mh/hps in 4 months

Great questions/observations Lurch Farmer.... I've tried to find a lot of research relating to plant manipulation by changing spectrums, but what I am finding out is that the plant lighting research is very inconclusive. It probably is one of the most studied aspects of plants, without consistency or understanding. I've read hundreds of articles and it seems each one points out different discovery's and conflicting information, so I think at this point, science as a whole is still trying to understand lights influence on plants.

For me, it seems that the majority of what I read did have a general consensuses that more light=more photosynthesis up until the plant peaks out (light saturation point). However I think that you may be on to something that its not the "daily" dimming but more of a monthly reduction of light period maybe having more effect? not really sure myself but definitely leaves room for many experiments in the future. I really would love to do a dimming vs non dimming grow to see the differences, in maturity time, in yield and other factors... But still have too many strains on hand to be able to do this at the current time.

Really with all this lighting technology, I think we still need more information and research done to fully understand how to manipulate light to our plants benefits. Especially Cannabis specific studies. I've found where certain species of plants were studied, and just between different phenotypes, they responded differently to light... but the same exact plants strain...?? so I think that really, plants can use any light, but depending on each species, phenotype and such, the results and details also change. I think now that the US Govmt has finally started allowing some leeway in regards to cannabis research, I think the next 5 years hopefully will produce more studies and research into our beloved plant.

re: Icemud's Intelligent Gro 2 LED Grow With V-Scrog - Going for 1lb & Beyond!

I found this a while back and may be some benefit to fluctuating light intensities to reduce the "mid day depression" as well as increase the "morning maximum"

This may be a good start to understanding plants needs and how to manipulate light intensity to give us better photosynthesis rates.


So its already been proven that plants don't respond to the morning sun, but because of their internal time clock "circadiun rhythm", they anticipate the sunrise and act based on this anticipation. Kind of like when we are used to our alarm clock going off every morning, we sometimes tend to waken before it goes off due to our body being "programmed" to wake at that time. Plants also are the same... So what this little abstract is saying is that they think that plants also set their photosynthesis rates and declines based on this pattern of intense light based on time.. So maybe this can be something we can manipulate by having a sort of random peaks and drops of intensity during the day (like clouds passing) we could reduce the photosynthesis drop mid day, and increase the morning maximum?

Effect of short-term variations in light intensity on photosynthesis of a marine phytoplankter: A laboratory simulation studyAbstract

Parameters of photosynthesis and growth were measured for a marine diatom (Lauderia borealis) grown in axenic continuous culture under three different light regimes: constant, simulated diurnal variation, and fluctuating. The light fluctuations were systematic increases and decreases in light intensity superimposed on the diurnal regime. In the first two regimes, a morning maximum and an afternoon depression in photosynthesis were observed. In the fluctuating light regime, the afternoon depression was less pronounced and the morning maximum was enhanced. The results may be explained by postulating a time-dependent value for the light-saturated rate of photosynthesis. Light utilization [mmol O2 cell-1 (E m-2)-1] was the same for the diurnally varying and fluctuating regimes, despite the fact that the peak light intensity in the fluctuating regime was double that of the diurnally varying regime.

DAY 4 Flowering!!!

So its looks like my girls just want to keep stretching which makes me happy as the scrog comes alive! LOL

Currently I have my lighting schedule set to 12.5/11.5 for the first week of flowering in which I have read will help give them a little more stretch, and I will be setting it to 12/12 for the remainder of the flowering period as soon as I see the flowers set on the plants. I will not be doing the DLR as I read that a 11/13 schedule produces up to 15-20% reduction in plant yield when compared to 12/12, so I will keep it at 12/12. I also read that if you flower under 13/11 schedule, it causes more stretch, but increased CBG cannabinoid content, however 12/12 produces more THC-V content so the study indicated that 12/12 is best (as studies show now) for a even and productive cannabinoid content. The study also suggested that in indoor grows with artificial lighting, its best to keep the lighting schedule constant after the flower sets, and not match the dimming profile of the seasons...(it didn't really give reason why thought) It also mentioned other studies that showed increases in just 10 minutes over the 12/12 schedule of light in a study of chrysanthemums showed a dramatic increase in value the plants produced.

I also am not using the controller and dimming functions, and have all 3 lights on 100% intensity for the entire daylight schedule. I really want to see what these lights can do plus for some reason the controller did not want to get along with 2 of my lights so I unplugged it.

After giving the girls the flush about 1 week ago, they are back to thriving and looking amazing! Good leaf posture and shine, no tip burns on the new leaves, and no discoloration at all.

I have continued to feed them every day, alternating between 1 cup of water and 2 1/2 cups of water every other day, and I have it mixed with some Cal/mag, epsom salt and potassium silicate (under 200ppm total concentration) and it seem to really get the plants going when I feed them this mix, within a few hours the leaves are looking very perfect and stretching towards the lights

Here are todays photos, both LED lights on, and off. enjoy
