Wild Strain From The Midwest

Dang they are going fast now

Right?!! I swear, every morning I come out, at least one of them has grown a couple inches! I'm jacking up the nutes so we're about to see what these ladies can handle.

Interesting that your leaves on those plants look like the 'indica' phenotype of the Lebanese strains that I am growing this year. Narrow and long and sawtooth edged. Contrary to popular opinion, hemp actually is a lot closer genetically to indica than sativa in the online published genetic tests. Also Lebanese strains are high in CBD, and seem to have a lot of hemp in them. The Lebby plants are a lot denser growing though (even with less pruning).

That is really interesting! I'll have to look into those. The further into this grow, the more intrigued I become with these ladies.
 
Just caught up this one too...slow day at work can ya tell? Just wondering what % light reduction the greenhouse cloth is. Is that in the specs when you buy it?

HAHA well good to have you here too!! This one will be a little more interesting.

It did not say when the specs on it. Lemme see if I can find it on there somewhere or in the box..
 
So I couldn't find anything on. The light it let's in...
But I have this Android lux app that I popped up lol
F1
Notice how it changes? That was when I was moving the screen of the phone. I did this on the top cola of each plant, trying to face the sun.

Hmmmmm we may have figured out the node spacing and stretch......
 
Wow! That's fascinating and I had no idea there was an Android lux app! Where is it reading from and what's the sensor reading in full sun outside the greenhouse?

Yet one more thing to measure!

So I messed with it and you could change the calibration.

Outside greenhouse, full sun

So can we call that a 30% reduction in lux? Also, what did you use to calibrate it? I just downloaded it...thanks!
 
So back to my original question about the greenhouse cloth, since it seems to be reducing the lux by 30%, is that just the trade off one accepts for keeping the heat down (or up in the winter) and the rain out? I'm just asking because I'm curious.

After growing a beautiful monster last year, then losing over a half pound bc I couldn't keep her dry, I will take the trade off.

This year may be an exception with the weather but I'd rather be safe than sorry
 
And it will absolutely be worth it! Also, I'm not sure we can count on any type of weather being an exception in the future...or maybe all weather will be!

So roughly minus 36k lux on the brightest of days?
That would still put us at 90 some odd thousand lux?
(This is how I measure nutes too lol)
I believe a 1000w hps is somewhere around 25k lux (trying to remember from indoor days)
If all of this is true, I'd still be working with 3 1/2ish times the light of a 1000w hps per meter squared.
I was growing toddler arms with 2 600w lol

Talking through all of this makes me excited! Being only my 2nd outdoor grow, I still equate a lot to indoor....you've just been a fantastic catalyst!
Thank you!!!!
 
Nicely researched! I wonder if I can use the "brightest sunlight" number to calibrate the app? Maybe you have to be on top of a mountain at noon for that...

I'm going use this app to see how my makeshift CFL area compares to the gloomy days we often get here. Excellent find and well done!
 
I use watts per sq meter myself. I have a cheap incident solar energy meter that reads in BTU/sq ft and watts/sq meter. I find it easier and more effective than measuring LUX or lumens, but that is me. Also many confuse wattage of the power source or light rating with the watts emitted from bulbs, which simply is not the case. With HID lights, the emitted light intensity falls off with the age of the bulbs as well.

Be reminded also that light falls off at the square of the distance from the source. Meaning? The sun is so far away that sunlight at the ground is for all intents and purposes the same intensity or energy value as sunlight say, 10 feet off the ground. 93 million miles less 10 feet makes only the slightest (and likely non measurable) difference. However, light from a HID or LED falls off dramatically in intensity and energy with the distance from the bulbs. For example, say you read 100 watts/sq meter with a light meter one foot from a MH bulb. At two feet the light energy will be 1/(2*2) or 1/4 the intensity at one foot, or 25 watts per sq meter. At three feet the light will be 1/(3*3) or 1/9 the intensity at one foot, or 11 watts per sq meter. At 10 feet? The light will be 1/(10*10), or 1/100, 1%, or a mere 1 watt per sq meter. Simple physics, and why sunlight kicks any indoor light's ass, regardless of the watt rating or size of the bulbs.

Sorry to mix meters and feet here... we in the US will likely never fully convert to the metric system.
 
Using my solar watt meter here just above the 45th parallel in summer, I generally read a maximum incident sunlight energy of 800 watts per sq meter at 1pm daylight time (high noon). The highest I have ever read with this meter was in winter with snow cover at high noon and it was almost 1000 watts per sq meter. Reflected light from snow is pretty intense, and why night is fairly bright in winter when there is snow on the ground.
