The low 40s is as low as I can get it and really that is pressing the low end of the VPD scale. I don't want them to stop growing.

i think you have done a fine job sir its in the hands of the canna gods now those sativas should be quite mold resistant i would have thought

Ace Seeds lists the resistance to bud rot as avg -high.

I'm not knowledgeable about VPD, but 40 RH sounds good to me.
Those buds are big, but they're not a solid mass of plant matter.
They still have that sativa openness about them.

I can't see anything nasty taking hold in there.

Thanks for the encouraging words. They are the densest sativa buds I have grown. So Far So Good though!

Very Nice! I'm amazed this is out of a 6" Rockwool cube.

I am as surprised as you. I thought they would be somewhat dwarfed by the small root system boy did they fool me. The Panama Red might have been close to 8 feet tall if I had not super cropped her main cola twice.

We have to look at the fact that these new ChilLed lights combined with the GreenLeaf MC 2 Part nutrients is a real winning combination.

I have been able to keep the RH ~40% and I am not seeing any more Bud Rot. I might still harvest the Panama Lemon tomorrow as she is very close with all cloudy trichs but I do like a little amber? The other problem and why I might wait is that with the super cropping is leaning all over the place I might damage the other plants trying to get her out?

Your efforts might have just a little to do with it as well. You have me interested in Rockwool as a replacement for Coco. Just curious as to what you think about running a 6" or even an 8" block in a Autopot tray?

I think it should work just fine with one caveat. Rock wool watered from underneath will develop a salt line inside where the nutrients stop wicking up. This happens in flood and drain that does not over-fill the top of the cube. It is simple to accommodate though by top watering once a week to flush the salts out.

If you start them like I do You could grow some monsters in an 8 inch cube. An 8 inch cube is 512 cubic inches while a 6 inch cube is 216 cubic inches so the 8 inch is 2.34 times larger than the 6 inch.

The Citrdelic Sunset 167g in for the cure. So with the estimated once I lost to Bud Rot on it about a 7 ounce plant.

Ok Gang this is without a doubt the biggest single plant I have grown. I harvested the Panama Lemon this morning. The top cola alone weighed in at 369 grams wet so maybe 3 ounces dry for the top of the main cola! I have not weighed any of the rest. One of the branches is over 40 inches of bud and several others are right there. I am blown away by this plant. I had to harvest it by cutting one branch at a time while it was still in the grow space because of all the inter-twined plants. I managed to get it done without breaking any of the branches on the other two plants. I made a video and will add it this post after I get it edited and uploaded to YouTube.
