They did ask @kbag and @Hydro first but then realised they both grow fluff... not bud. So I got the sponsorship

Hey @Keeno Looks amazing! So what height is it that you have settled at? I have my 240w FBar and its' Wee single FBar freind sitting at 16 Igches above the highest tops.... do you think they could be lower?Keeno wrote: ↑Thu Sep 02, 2021 10:12 pmUpdate
I think we are about a week from the change to flower. The lights are certainly doing the business so far. I think I've found the sweet spot as in height now. Any closer and I start to see light stress, as mentioned before this shocked me given the wattage for the area. The plan is to tuck these again tomorrow, I think this will fill the net, if not another 5-7 days and it will be done. I know the strain so will be able to get the height perfect through the stretch period.
Feed is now at 1.25ml per liter of Canna A and B per liter. They have just finished a 3-day cal-mag load up which means I've added 0.5ml per liter of Plant Magic Mag-N-Cal to the feed and given them a good foliar feed with Epsom salts. PH is now set to 6.2 to aid the load up ready for flower. Plants are getting around 3-liters a day.

In veg around 18-inch on these atm. The F-Bar you have are more powerful up close. The reason is the test light produces similar or more light but by running softer. Meaning the LED are running at 10% power, where as the F-Bar LED diodes may be running at 80% power. Them percentages are lliterall random numbers off my head but you get the point.Rixtar wrote: ↑Thu Sep 09, 2021 12:48 pmHey @Keeno Looks amazing! So what height is it that you have settled at?

So the X-bars will need to be closer than the F-Bar in veg and more importantly flower. My custom 720w in the pictures is far higher than both the ISH530 and the test X-bars.
With yours once in flower I'd lower daily by just a inch. Look for signs of light burn or stress until you find the sweet spot.

Update
I've held pout as long as I can on these. The net is bursting and these are ready for flower. Up to this point, the X-Bar has kept up with both the custom 720w and the ISH530. The real test is about to begin. The plants under the X-Bar definitely seem healthier which I'm excited about. In my previous HPS v LED it was the plant health under the LED that was the biggest difference and IMO attributed to the more delicate aromas and overall weight of the flowers.
These pictures were taken before another tuck into the scrog:



These were taken after:



The plan is to let them go from day 1 flower, no training. This will show some structure to the plants, how they react to the light and if the X-Bar can push through 1-2 feet of tops.
Feed is currently at 1.25ml per liter Canna Coco A and B. PH set to 6.0.

Looking awesome so far bud. What’s the biggest difference you notice on the plants under the different lights so far?
