Question 1

Can these be used in the bottom of a planter for lime hating blueberrys  for drainage please

Accepted Answer

Yes these can be used in bottom of pots to help with drainage. It's exactly what i use them for.

Question 2

what is the volume (m3) and saturated weight of 45L?

Accepted Answer

Sorry Salt for answering your questions and sounding a bit prickly but it does say on the advertisement "45 litre bag" and as there is a 1,000 litres in a cubic metre I think that makes a 47 Lt bag .22 cubic metres.As for the "saturated weight" these are aerated clay pebbles and as such do not actually 'hold' water.The aerations simply provide a greater surface area for water to adhere to as a 'damp coating'.The weight really is the actual pebbles, which is 13 KGs in the bag. Yes I know I also sound pickybut the answers are all in the ad for the goods. Sorry for being a git! O'Keef

Question 3

Has anyone used it for vegetable growing in troughs or raised beds? I have a container and I wanted to lay some pebbles at the bottom

Accepted Answer

I have used and reused these pebbles in a number of ways.

Firstly I use them as the filler in a basket to hold the plant in a "Kratky" system.  In this respect the pebbles were fine once the plant had laid down roots.  This is used for both tomatoes and cucumbers and is very successful.

Additionally I used the pebbles in a trough containing Non-woven Breathable Permeable bags.  In this respect all the nutrients and water is poured onto the pebbles and not the bags.  I have used this for growing chilli peppers and tomatoes, with excellent results.

Question 4

Do they dissolve while contact with water??

Accepted Answer

Simple answer is no they do not.  I put the pebbles in a bucket of water, prior to using them (to clean off the dust).  I have left pebbles in water for weeks without any adverse affects.
