Those little HLG 100s kick ass kazzy,i have 2 of those also.
Big I also use to run quantum t5s in veg,if you switch to LED you will be shocked at the power difference with no loss in light or plant health.
Katsu like kushyman said you need to run higher temps with LED,I run low 80s but some run up to 85 (which also saves on AC costs).One other thing ill add is you need to run more calmag with LED.
I am definitely still learning these lights after just 3 runs with them but i cant find much downside except price which i honestly beleive i will recoup fast.Because of where i live(so cal,uggh)my power is crazy expensive and goes up in three tiers from 18cents to 26cents and finally 43 cents a killowatt hour so i had to do something.
I have a half a dozen gavita 6/750s and just as many sunsystems 315s if anyones looking for a good deal,lol.
