I have a marshydro 300 watt with 5 watt chips, got it from Amazon- it has the logo sticker on the front but the sticker on the back is plain and says the model # is MZ-60LED
Any thoughts on this? The vendor name on Amazon says marshydro but I have seen the black stickers on the back in photos of others , wondering

As you purchased from Amazon, the light was shipped from Amazon FBA warehouse, and they did some special adjustment on the lights too, please don't worry.

Thanks for the response! I love it so far. What did they do to it? I am also thinking of buying a 600 watt old series, what would that be comparable to in the MARS2 series?

You can use one first during veg, when flower put them in. Two in that space might get a little hot.

What about if I keep the tent open. Will the waste of light harm the plant?

I would prefer to use a bigger fan and keep the RH above 50%.

Is there any other way of raising the RH other that a humidifier?

Yes bro put a damp towel or a couple of bowls of water in the room or spray the walls with a fine mist sprayer
