my mini cold chamber

[Robert]

This is only a trial, where i kept my intermediate and H/L neps, and seeds. Run by a blower at every 45 mins for 15 mins with aid of timer, 2 blocks of ice, floor were laid with wet sphagnum moss. The cover was slightly open to let air in/out, reinforce with wire mesh. The transparent plastic sheet allow for filtered light.

The poly box was left in the open. No ice was added during the day till 7.00pm, though sometimes i missed placing it for 1-2 days.

Nice... now the question is to see how "sustainable" is it to run this setup for long term... Thanks for sharing.

Hmm interesting cos when i tried something like that and put the ice in it the humidity drops but yours remains at a high level.

placing 1-2 block of ice is not a peoblem, The real problem was when the plants outgrow the chamber.

misting the inner wall of the box and keeping the base of sphagnum moss wet will maintain high humidity.

So when u didn;t mist the inner walls and moss did the humidity go lower??

Yea...nice, even thou a bit of a hassle to replenish the ice it seems to work perfectly.

yes,it goes to low 53%. One way to ensure high humidity, besides misting the inside, was to cut out a hole 3.5" x 3.5" behind the blower to suck in fresh air.

outlets that supplied scientific equipment and lab chemicals. cost RM80.00. Things in east sold at slightly higher than peninsular so you can expect lowere price.
