"What Experiment?" I hear you ask. The links at the bottom of the post will see you right.
Well, here is what my little seedling pottles look like this evening. Lovely and lush, a little overcrowded, but that's okay - I want a good number of plants in each pottle to give a more reliable result.
I have not moved their positions around - so the one that is "top left" has always been "top left" and shall stay that way for the next 4 to 6 weeks, and ditto for the other three pottles.
On Tuesday I set up the different water treatments but have been slack about blogging (while being un-slack about parenting), so here goes now.
As you can see, I have used 4 more-or-less identical jars (Chunky Marmalade for those with insatiable curiosity about such things). There may be minor differences in the amount of scratching each label has received but I have not paid much attention to that. Right this second, each lid has got a label on it identifying which water is in the jar, but when Merl gets home from being a responsible youth group leader (they're playing Laser Force, the lucky dog) I'll get him to label them A,B,C,D so that I won't know which plant is receiving which treatment. The jars and lids were washed in the dishwasher all at the same time.
Details of the treatments are;
- Plain tap water - from the cold tap after it was running for a bit
- Boiled in the electric jug - start with cold tap water as above, boil it, let the jug turn itself off, let the water cool to lukewarm before pouring it into the jar. We have a stainless steel jug with a concealed element.
- Microwaved in pyrex - start with cold tap water as above, fill a pyrex measuring jug, use the "Auto reheat" function on the microwave and repeat the 'reheating' until the water is properly boiling. Stir cautiously with a stainless steel teaspoon each time the microwave beeps or stops (but not the last stop - just leave it - microwave-boiled stuff can be extremely hot). Leave the jug in the microwave until lukewarm then pour water into jar.
- Microwaved in plastic - as with pyrex but using a 'microwave safe' plastic container from the last time we had Indian takeaways.
Here are the links to what this experiment is all about...
Is Microwaved water safe?
