i looked but i cant seem to find the answer....


what exactly is "R" value?

I think it means reflective value

Here is the wiki answer
R-value is a term predominantly used in the building industry to describe the insulation properties of certain building insulation materials. Its use is limited to situations where thermal insulation is achieved by retarding the flow of heat through the material itself rather than reflecting radiant heat away. The higher the R-value, the greater the insulation. Although they offer a useful means of comparing the performance of different products, other factors need to be considered in maintaining thermal comfort (see building insulation).
R-value is a measure of apparent thermal conductivity, and thus describes the rate that heat energy is transferred through a material or assembly, regardless of its original source.

so if foam has a very high R...

and R is used to describe insulatability? why wouldnt it be good? the higher the number the greater the insulation?

i was going to spray the foam down then wrap with mylar or poly!

they got this shit at home depot where its two layers of bubble wrap that have been aluminum coated on both sides. reflective thermal insulation, reflects 97% of radiant energy... comes in two and four foot width rolls of twenty five or fifty feet

is that insulation? would that help?

im sure it would, they use it for attics, i use it over the windows near my grow space, and i constructed my grow tent out of it. im pretty sure the air space between the foil layers created by the bubble wrap insulates pretty well... might wanna check into it, if nothin else makes excellent wall coverings for grow rooms

Foam is best.

duely noted...only thing about that spray foam is that it could get a lil messy. im pretty sure i saw some foam mylar combo on the spaceshuttle, thats workin well...? looks real official

I harvested some Afghan the first of Jan 08,
and now 6 months later,
I just rolled a joint
that is as fresh as it was
6 months ago.

I like the vacuum containers for long term storage.

They are pretty expensive,
around $20
and I couldn't afford enough vacu-vins
to cover my harvest.


I also live alone
and eating all the leftovers can be a challenge,
sometimes I have to throw away some food
because it spoiled before I could use it.

The other day I was at the grocery store
and found this item in the ziplock isle.


So I invested the 20 bucks
and got the gear.

I used it to seal peanuts,
grapes, blueberries, carrots,
celery, and cookies.

Works great, and keeps the stuff fresh.

After you open the bags a few times
the ziplock seal can start to leak a little.

The bags are about $1.30 each,
so I try to use them a few times,
but they don't wash well.

Anyway, I thought I could use the plastic valve
to make some vacuum jars,
and it works.

Here are some pix.

First cut the plastic one way valve from the ziplock bag.


Second,poke a small hole in the lid of the jar.

Third, use the stick to apply a thin film of glue
to the blue ring around the valve
and and stick it to the lid
so the hole lines up with the center of the valve.


Give it about an hour to dry,
and then use the pump to pull a vacuum.


The lid does not need to be screwed down tight,
because the center part is vacuumed sealed.

This cost about $3
if you have to buy the jar.

The vacuum pump is about $10
and includes the 6 "C" batteries.
