HLG 30 watt UVA Bar Posted by NoobBeGrowin | Jan 10, 2022 | Grower Questions | 2 | What’s up DGC!! Anyone use the HLG 30 watt UVA Bar? I’m getting a new grow tent from AC Infinity and I’m grabbing a HLG Blackbird to go with it. Eventually I wanna get the bar but does anyone have advice on best use?
Mangrow_Goodbud on January 15, 2022 at 4:25 am HLG recommends 8 hours on in the middle of the 12 hour light cycle, from about week 5 until harvest. The goal in adding UVA is increased resin and terpene production in late flower. Log in to Reply
GardenOfWeeden on January 18, 2022 at 1:07 am Look into the AgroMax PureUV T5 fluorescents. Much stronger lamp and it includes UVB and UVA, which the plant can utilize both. UVA is a spectrum gap but you’ll get much more mileage from the 75% UVB 25% UVA of the PureUV. I run mine through the entire flower cycle in my perpetual harvest room that basically has two zones. First zone is for incoming and gets 5-minute intervals three times each light cycle. The second zone is basically weeks 4-8 of flower getting three 15-minute intervals. This is my first run, and I will tell you that my trich density is higher and the heads are much more pronounced. I flower in a loft with a limited ceiling height so preventing stretch is a big priority and UV achieves that, plus I do not have to spray for insects and I do not have powdery mildew. Log in to Reply
