Transpiration bags

Plants require sunlight to photosynthesise, transpiration is part of the cycle, thus no sunlight, no transpiration.

Black will allow the plant to 'sweat', but it will not produce a great deal of water unlike the process of transpiration.

As for the clear bags, try a gardening supply store or similair, as I have seen mulches and the likes sold in clear bags in the past. Worht a try

Bunnings sell clear plastic dropsheets for only a couple of dollars. You could fashion one of these into a bag like shape to catch water.

Mike talk to a pallet supplier, we have HUGE clear bags at work that the guys use to cover stuff on pallets

This company provides specialist training to the QLD government and a few other organisations. i am not affiliated with them other than I used to work for the director. Not only does he run training, he also sells survival kits and transpiration bags. ( I have several and they are excellent)

Try a bed supplier Mike.

New beds usually come in a big transparent bag.

Save your money and your time. You can have my ex for free, she is a transparent empty bag. She may be even able to pump up your tyres, engage your ARB Diff locks, inflate your Air jack and air mattress as she was full of hot air. Oh she wont blow anything real important or do the house work, dishes, vacuum, iron clothes, mow the lawn, gut fish, cook food, get beer or make intelligent conversation. Yes she was like a Bull with no horns and not legs. She woudn't buck, f@@@, just sit there and bullchit.
I hope this helped regards,
