oldtimer1 Posted January 19, 2007 Share Posted January 19, 2007 Here is the results chart. There are some interesting comments on varibility of compost, their words:- You could be forgiven for assuming that one bag of compost would be the same quality as any other bag of the same brand. But, in fact, this is not always the case. We found dramatic differences in plant growth between bags of the same compost bought from different parts ofthe UK. Our previous trials have shown us that this bag-to-bag variability can be a particular issue with peat-free compost and this year's results tell a similar story. Homebase Peat Free Multi Purpose, Miracle Gro Eco Sense Peat-Free and B&Q Peat-Free Multipurpose all showed significant variation between bags of the same brand. Variability was also a problem with the B&Q growing bag, which is peat-based. It scored well in our tests overall but we are unable to recommend it because of its variable performance. This is a shame because grow bags are generally lighter and therefore a more manageable alternative to the larger compost bags. Variability between bags of compost was clear to see in the section of our trial involving growing on young plants. Each pot contains compost from four different bags of Homebase Peat Free Multi Purpose compost.

obscure_shadow Posted January 19, 2007 Share Posted January 19, 2007 not really.. you can tell how well a compost is going to do by how it smells and it's consistancy really... that is unless this stuff has chemical ferts added ? Link to comment Share on other sites More sharing options...

compostverte Posted January 19, 2007 Share Posted January 19, 2007 Thanks ot1, how did you get on with the Westlands hanging basket compost in the end ? I'm planning to try it for the later pottings-on this time .... Link to comment Share on other sites More sharing options...
oldtimer1 Posted January 19, 2007 Author Share Posted January 19, 2007 Thanks ot1, how did you get on with the Westlands hanging basket compost in the end ? I'm planning to try it for the later pottings-on this time .... I like it the best of all the Westlands compost mixes, all have done well for me except the peat free, that was total cack, the bud produced was good so were yields and it smoked very well. Because it has water retaining crystals, it suits me very well, if I absolute saturate the pots so the capillary matting is soaked as well I can go away for 8 days at a time with no problem, thats with full sized plants in full flower. I think 6 or 7 days will still be manageable in full summer. For normal watering/feeding I water less at a time, ie round every four or five days. The only amendments I make to the compost are adding a little rock dust and an inoculant. B) Link to comment Share on other sites More sharing options...

You can read all about it here. Also you say you've added a ratio of 3/1 perlite. This will cause you no end of problems imo - there really is no need to add that much perlite, if at all. Is there a tiny amount of perlite in the compost you've got? If so it's the older batch. If not it will be the new formula which peeps have been having a few probs with.
