Raise light for a full day or so to let them “adjust” to the HPS, much hotter than the HO’s.
When I come from my T5 Ho’s to the Gavita, I raise the gavita a good foot over where I normally would run it, and lower watts to 400. Next day I bring it down to height I want it at, the 3rd or 4th day crank it to 500, then by day 5, up to 600 where it stays until they get some size to them…then to 750/825
I’ve been thinking about this too, in my case MH to HPS (or LED) anyway, I’ve been wondering would it not be better to run the first two weeks under 12/12 with MH (Blues) then switch to HPS (reds) after two-three weeks? Instead of switching to the HPS with the 12/12 switch.
Actually this little vho almost runs hotter than the air cooled hps.
I understand about intensity, I’m just wondering which would give a better ratio to m/f, I normally run at 65% females.
Running the first 2 weeks the way they are or go a head and throw the air cooled in?
I have adjustable ballasts so it’s not like I’m gonna throw 600 at them right away.
