Whats better for reflectivity & lumens?

[Twils]

I was wondering what would be better for a small grow area say 19"w x 24"l x 48"d flat white paint on the walls or mylar? Lighting would be 400w MH for veg and 400W HPS for flowering, Thanks! +rep!

Mylar is better, but in that size space I would go with flat white.

ok awesome, this is my current set up not sure if its clear or not, but have already flat white walls, covered in mylar lol just wasnt sure what was better to cover the lower foliage

Great looking plants! Flat White is *almost* as good as mylar... The walls look perfect though. =) Great job!

Thanks! So just keep the mylar?

I would keep what you got looks good enough to me, adding white paint wont make any dramatic difference just wasted money and time if you ask me, plants look good and healthy

Well the walls are already painted flat white, but just covered in mylar. Just wasnt sure what I should keep being more "reflective" I guess for the lower parts of the plants! Thanks +rep!

You should read his post again, he already has flat white walls and mylar,
why tell him to buy emergency blankets as well.

yo you could put mylar disks cut with slits around the trunks atop the pots and that would keep the light from drying out the soil and reflect a little more light, and also keep the temp down on the root mass.
