more light can never hurt but the mylar is just going to make the most use out of that light. i think mylar is worth it but more light would be better.

i picked up some light proof curtain from wal-mart. that seems to work well also. i hear mylar and other shiny material is highl reflective while flat white material such as paint and poly curtain diffuses the light, while directing 90 some odd percent of the light back at the plants.

it depends on what kind of mylar you get. the silver is very reflective and is almost like a mirror but you can also get mylar with white on one side and black on the other. the white is reflective and the black discourages mold. prepare to pay heftily for the black & white tho.

ok ive seen that. im sure it would work but i think the mylar is better. 95% reflective, it really does work well. this is where i got mine. the only problem is the mylar is only 1 mil here. but its cheap.

yeah, that reflectix is 97% reflective, and all you have to do is run a couple of staples through it. i've been re-using the same roll for 3 years no joke. plus it has the dimpled structure for better diffusing light instead of a hot spot reflection. i guess in the end people use what suits their situations. what works well for one, may not work well for another.

wow thats really cool. one thing about the mylar is its a bitch to keep flat and wrinkle free. and once you crinkle it good luck to ever get it as good as it was. i hear the black and white is great if you are doing a closet grow. but i might have to go to home depot and check it out.

if you dont want to spring for another hps just get a couple of cfl's from home depot.
were using fluoro tubes, t5's, i was thinking about just getting another 23 watt CFL, yeah. but then we'd need another timer, but theyre only like 6 bucks...
we'll just get that reflectix stuff from homedepot that reflects like 96% and has little diffuser bumps and see from there..

I got some 4 foot by 8 foot sheets of styrofoam house sheathing at Lowe's. It's white and I made walls out of it. Works great! They also have 4x8 sheets of styrofoam covered with the reflective aluminum stuff. The stuff I got was $7 a sheet. Very good for insulating my cool bloom room too. Hope this idea helps! If option is mylar or white paint, I'd go flat white paint. Works better with MH Mylar supposed to be better for HPS I read in a Ed Rosenthal book somewhere.

I got a roll of mylar, its a good idea, but useless in the end. If you spray neem or organicide, your never gonna take the time to clean it off the mylar. I'd go with flat white paint, Panda film next, and then mylar begrudgingly.
I'm interested to see the reflectix stuff though.
