I am now at 100% coverage of room. Lowered lights and now seeing incredible dark greens. But let's take a pic in a few hours. And remember, it's just water with like 700ppm co2.

Lowered again, yellow below top canopy is greening up clones beneath.

Just a tip. You can’t tell anything in a few minutes. And plants like stability. The fiddling is helping to stress them more.

try making an adjustment and checking in 4 hours. Plants are on slow time man. Not anxious human time. They need time to adjust. You are only seeing what you want to see.


and you sure don’t want to stop reflecting surfaces with hot black plastic. Bet that will stress them more.

Good luck man. The plants still look fine. Just like yesterday.

Ok will do. Just trying to get lower branches to green up. Yes did drop again. Damn if it isn't greener. So I am stopping for now. Will check rigorously if any problems arise...

Yeah man. Sorry but I want to see a garden in flower before I change my interior color. To each their own and I have no idea your space time expected yield etc. again to each their own. I grow monsters compared to that all the way thru veg with one 315 cmh lec etc. whatever u want to call it in veg and two in flower in a 4x4 and net close to two lbs everytime. They don’t burn or stress at the top. I came up with a way to hang the light from below the bottom so I can put them
Up all the way in the box. The plants do fine. These are getting flipped in one week
They are approx 2 feet tall right now but I give them extreme lst in that box. Bent down backwards and broken on occasion training them. Fuck it it happens. Just tape it up and support it be fine in a couple days. They’d be five foot tall if left alone. I love those lights and am not convinced blacking out is going to help
Them. And sounds hot

Dude you have a killer grow. There is nothing I can add, except it may help in stretching. That's it for now, jury still out. But I am lowering and it's getting greener. But it's so low now, we are talking less than 3' square. Which is a bummer.
So, tomorrow I will slice some of the Orca in 3' strips, then find the sweet spot on the wall.
one wall at a time, then remeasure. I am hoping (!) That I can use it for SOME reflection. But now this, its definitely a problem. ..

So right before lights out I put up a 1' panel of Orca. Spread lights apart and lifted slightly. One plant on other side is still suffering. So placed it on panal panal side.

Good morning,
Disaster struck again when I added a simple panal of Orca.

Scrambled, pulled lights up and down (slowly), made other adjustments on humidity, etc etc.
HOLY CRAPOLA! Same exact crap I was dealing with before with Orca! I love Orca! Not with CMH!
GOT DISGUSTED again. Pulled them up to 7k lux and went to bed....
Woke up and this is what happened.
It's hard to see with camera, but now there is not really any yellowing......FINALLY.

O ya 24/7. Still have to keep humidity up, BUT humidifiers used only a third of what they daily burn. So plants are transporating. Now i need to water again. Thinking about giving big girls first week nutrients, but with organics...hmmmm.

You sure your light cycle isn’t messed up? Those plants look like they’re revegging. May be stress induced as well.
