Yield and bud structure.
I'm very pleased with the yield this plant produced from a 7.6L pot using a Blumat system for the first time and minimal initial training, just a few toppings for 10 main colas and a bit of bending with plant bendz. The plant was large and stretchy with buds well spaced out and they were nice and firm from top to bottom, top and mid buds being solid with large dense calyx. The extra bit of bending to open her out and keep her down as she stretched contributed to the mid canopy buds being pukka, as well as the genetics. She grew well with no real problems on a one feed fits all, but I tried my best to base the feed around this one with it being the biggest. She didn't really go hungry through flowering but got a nice fade on near the end as I reduced the nutes. The idea was to make all the plants in the tent happy and that wasn't an easy task with a 6 bottle feed being added to rich compost with slow release guano, so the SAH suffered a bit of over feeding. I wasn't sure if I'd put the TPFV on plain water too soon or if it was the low humidity that caused a lot of the older leaves to curl up in the last week or so, but they came off steadily and allowed more light to the lower buds. I reckon it was the low humidity causing over transpiration. The LED above her was turned up steadily throughout the flowering stage to avoid stress and I only got as high as 230w by day 44 before noticing stress and tell tale signs of Calcium problems appearing on some of the plants (I had lowered humidity for fear of rot). This wattage was only maintained for 3 days before I dialled it down to 220w on day 47. I started dialling the far red down on day 56. It was fully down by day 59, leaving the blue wattage at 183w for the rest of the grow. This totalled 498w along with the CMH at the back. At a guess I'd say this plant and the other 2 Sweet Seeds plants at the front were only getting about 100w from the end of the CMH reflector, so about 320w total from day 47 to day 59. Then 283w from then until chop. So I was quite impressed that this plant yielded 139g, just shy of 5oz :D I'd recommend training this plant low and wide for a monster yield. Just make sure you have the lateral space because she will go wild, even if her final pot is well rooted out before flowering and day/night temps are close. I could have maybe tamed the stretch a bit more by turning the power up earlier but I was aiming for a stress free grow and also higher lamp power might have negated the close day/night temps I was trying to keep.
