HPS VS AGRO

HEY guys, so i purchased a 600w agro bulb,
but i heard mixed feelings about it...
what do you think?
my setup
-SONLIGHT Digital Ballast 4D (Dimmer 250 / 400 / 600W / SL)
-AGRO 600W Sonlight bulb
- LONG-GLOSS 50 V hammered riflector
- mylar all around, 4x4 foot grow area
-atm 1 big fan, but il buy another small one,,

i have another bulb which is Sylvania SHP-TS 600W Grolux.
i was suppose to return it and get a refund but idk if there is any difference between the 2...
and if i plant 5 or 4 plants what do you think my yield would be?
il buy the winner a seed when the grow is done from royal queen seeds...promise

many good compares on Yt

I prefer the Son-T by Phillips

but have a draw full of others

just for backups

naturally ...lol

good luck
