temporary light screens?

Hi,

I have a relatively open space in which I would like to grow.

It will be divided in the "usual" clone/veg area and a flowering area.

I would like to have it be as flexible and "reconfigurable" as possible.

That means sealing or containing light from a 24/0, 18/6 photo period and a 12/12 flowering period.

Does anyone have ideas/expeerience with consructing temporary barriers that are "easily" reconfiged but seal off nearly 100% of light?

I would like to able to "peel" back or gently move the barrier(s) on a daily basis to tend the grow.

I have though about making wooden lattice structures covered with something like Foylon, but can't think of a way to seal the tops and bottoms and still make them moveable.

Perhaps black rubber "ribbon" or weatherstripping top and bottom.

If I make a protoype, I post a pic

TIA for you help/suggestions

Just a cautionary note. Test any light screening material for flameproofing. I was going to use some black plastic ground cover material (meant to keep out weeds outdoors) as a curtain. Since the lamps emit heat I took a snippet and put a match to it over the sink. Instant napalm!! Melted and stuck, red hot to my thumb. Luckily it landed on a guitar callous or I'd have had a very bad burn.

Ive seen people use black/white poly.They use velcro on sides and bottom and use a string to hold it in place after you rool it up.This would work with any light tight flexable mat.(flame resistant of corse).
