You ask and you shall receive...I actually posted on youtube this morning before this all went down....
Im sure you stated this already but i dont want to read back through the whole thread, how many plants are you running per light.

I just watched your newest video. On the subject of metabolism. Are you watering the hps side more often than the led side. Kind of goes with straight coco yielding more than straight soil. Coco plants have to feed more often and more quickly and therefore have a faster metabolism. Interesting about more heat speeding up metabolism. Like us. We work out or do labor and sweat and get hot. Aside from dehydration, our metabolism speeds up. I never thought of plants in the same way. My garden is roughly around 80 degrees. I used to trip on the high temps. I think plants can handle higher temps under led / induction rather than hps can. My induction plants in veg water twice as much as led plants. In flower its the same. Watering every 3-4 days.

Looks great gg. Love the show;)
What's up, glad you are checking in still. How is led treating you so far?

i made a post about heat/radiant heat being the main reason plants do good.about 2-3 yrs ago,and just a few weeks back.
im very happy to hear that from another person.
this is something i really would like more talk on.
and your doing a damn fine job.
Thanks you sir. I remember. But it's not exactly what we think/thought. I'll get his response up on here for you guys to read.

Ambient not the goal, leaf temp is the real key. I need to get an IR thermometer to show the difference before it's too late.
As far as watering goes, they are actually pretty even. Watered at the same time and the led usually get the most dry. Nutrient requirement is more on the hps though despite same amounts of waterings/feedings for both sides.
 
Been subbed to this thread from the beginning :) wouldn't miss this show.
I am in the process of purchasing another a51 unit now. So far I've been using it in the veg tent and it's doing a great job. I should be flowering some plants under it soon.

Once you have the IR thermometer, how do you control the leaf temp? Especially if it varies from the ambient temp.

I know what your light guy is saying and I agree, that illusion appears but I dont think it applies in this case, both your lights are killing it, watch the hid side sway with the fans, thats not false weight or airy buds, thats bulk, I live in south florida and I run canopy temp 88+ atleast 5 months a year, air circulation/exchange is what matters, my buds are just as tight in december with 76 degree canopy temps as they are in july with 88 degree temps. I dig the led sides bulk/frost but that hid is nice, frosty and heavy. Apache has earned my respect.

I've mentioned it before and maybe in this thread too. I gave my friend a cut that he grows under HPS and mine is under LED. By the end they almost look like two different strains. His has larger looking main colas but in the end I get more grams per watt than he does. The temp metabolizm thing makes sense since it's known you can raise your co2 levels in a warmer garden. His plants look like they should yield more but if you say the cells are expanded and holding more water that would explain it. His HPS colas also look leafier than mine,have you looked to see if there is a noticeable difference in the leaf ratio of the colas between the two sides?

Hey GG, not to derail your thread but I think you may be able to help me, I woke up this mornin with a hair up my ass and decided to buy a "personal vape device" i got the globe to run bho and such but I want to run a tincture or somethin in my juice so I can smoke that fucker all day, you cali boys got that worked out yet? I read about doin pg on the stove like butter but my vape guy says it doesnt work well, any inside knowledge for me?

That's some good info man, any chance you could produce some pics? If not that's understandable

I have lots of pics in threads I've started here at RIU of my grows but I've never taken any pics of his garden. It's funny now that I think about it but he takes pics of my grows every time he comes over. He's really amazed at the plants I've grown under LED,especially the ones I grew with the home depot LED bulbs. I won't be able to get any pics of his for a bit because he just chopped his whole flower room over the weekend and he won't have any going in to flower for at least another week.

Very tempted to try CO2 in the future if it's worth it in my tiny tent!

Quick question GG, I'm running two leds now, one I have positioned horizontally over the young clones and the other light that will cover the rest of the scrog is at an slight angle towards the plants atm.
Once the scrog fills out should I have both lights horizontal or would it be better to have them both at a slight angle to give more crossover of the beams?
They have 90deg lenses and 3w bulbs btw :)

Did you divulge to the plant physiologist what plants and what light levels you are using. His explanation that the same light- and CO2 levels will have the same carbon fixation might hold as an approximation for lower light intensities (the linear region). But at 1200 umol/m2 you are far away from linear. A higher temperature will lead to larger stomatal opening -> better gas exchange -> higher internal CO2 concentration -> higher carbon fixation rate. In other words the light saturation point shifts in your favor.

Just looking at the buds, the ones on the right are ahead in terms of structure, they are not the same buds as on the left with inflated cells.

Just my two cents on co2

Never will i run co2 from a tank and regulator, too much work for small increase. And too much money adds up by excanhging tanks every week.

I highly rec a propane burner with exhaust ports, more efficent with less having to exchange bottle every week. More like once a month. Plus exhaust ports make it much easier to handle in terms of heat. And of course ur going to need a co2 controller or a chh4
This one is expensive, i got one for about 300$
I guarnetee the co2 tanks will pass the 300$ in one grow.

Try propylene glycol mix it with concentrate (hash, bho etc), and put it in an E-cig. One that takes the juice.

When increasing co2 levels .you need to increase o2 levels as well.
imo adding co2 is best for sealed rooms. If you run in fresh air from outside via intake and exhaust. You will have plenty of co2. You want your o2 levels higher than co2. For proper respiration.. Outside air is less than 1% co2.

Interesting. Blue light also increases stomas activity.
Ya he nows what's going on. That's why I said it was a very simplistic possible reason. Other things happen in reaction to compensate like you say. I' want to see how increased co2 will effect the led.
Gavita says it's linear to about 1000µmols. Then begins to diminish. But light saturation is a ways away. Farther than I am away from

30% isn't a little. Just 15-20% is worth it. That turns a good grow into a great one. And a great one, to a record breaker. And probably a poor one to decent one.
Even if the vent helps...its more heat than I want.
Plus I got 3 free tanks...so I'll get to see if it's worth it for when I have to pay.
And since it will be all led, there will be less need to vent and waste. It will be totally sealed, not having to bypass vent the hps is key.

1200-1500ppm. Clearly shows it's benefits in many actual applications and on paper.
With just intake/outtake it should be right around 400ppm CO2. Not even close to what is used for enrichment(1200+).


But less than 1000ppm and there isn't a point.
