cheers mate, I studied your automazar grow many times during this one.... especially with regard to transplanting into larger airpots.... I think that was one of the many factors here.
It's a 1.4x1.4m, but it sags in massively to 1.1 LOL, but only in the middle.... these girls were way above that.
This grow has been a chance to compare lots of lighting configurations, I had 600W MH, 600W HPS, Helios 6, Helios Pro2s and Photon 6 to play with......
AU1 had MH 600W and the AU2 had Helios 6 and a Helios Pro 2 during veg... about the same, Watt for Watt. and in bloom the AU1 had the Photon 6 and 2x Helios Pro2s, and the AU2 had a Helios 6 an a Photon 6..... both plants were roughly the same in terms of size and yield. AU2 had less issues with heat stress, but that might be due to better airflow.
It was too hot to use HPS in flowering, the plants were too big by then
.
With AU2, I also had an opportunity to compare Helios versus Photon.... in the end, again, both were similar in terms of yield and size. I noticed the Helios side was wider but the colas on the Photon side were deeper and the buds slightly chunkier. The photons have a narrower field of coverage, but penetrate deeper into the plant. The only issue with this is that the fan leaves in bushy plants may prevent light penetration. I moved the photons a couple of inches every few days to change the light flow. I try not to pluck any leaves at all throughout the grow, I figure they store all the sugars and energy etc the plant needs for good big flowers.
I noticed the Helios Pro 2s were more powerful than the standard Helios.... 2x Pro 2's were almost on a par with the Helios 6, and buds flowering under the Pro's had more trich coverage and ripened earlier compared to the standard Helios.
With all this Sativa dominant bud sitting around, I have decided to grow an Indica or two..... Automatic Northern Hog (TH Seeds) and Blue Auto Mazar (Dutch Passion), are the options, but the Hog has reportedly big yields (350-550g/m2) and high potency (17% THC) and is 100% indica, as opposed to BAM, which I grew before.... a nice smoke but I didn't get massive yields. I might also do one more Auto Ultimate..... why not!
