It must be 40 years ago since I last used a smoke bomb in the greenhouse! To really be effective you need a fairly airtight greenhouse with the vents and door closed. It is advisable to tell your neighbours what you are doing as the greenhouse will be full of smoke. One of our old members used one i...

Move them outdoors would be best. This recent hot weather has set back a few of my plants on the top shelf of the greenhouse and that has four vents in the roof unlike most conservatories. I have even bought some shade cloth for the greenhouse not needing it in the past. We have not been used to hot...

As long as you put "rare" or "choice" on any plant on EBAY no matter how common it will sell for a stupid price. However a plant that size has taken a few years to grow, but not £437 worth. I like then adding postage is extra at £5.50p. The main attraction of the C. cinerea group...

As I understand it the correct way to restock habitat is as with the Kew Millennium Seed Bank. Collected seed is stored and never germinated until needed to refresh their original habitat. After germination the plants are returned to the habitat the seed was originally collected from. Not further pr...

The problem is always the source and whether you have collected plants or seed material direct from habitat. Or are the seed and plants under those numbers second or third generation obtained from nurserymen? If so you can never be sure enough precautions have been taken to prevent open pollination ...

I don't know the flower colour variation in the S. breviflora population, but as a matter of interest this was originally an offset years ago from a genuine Cardenas specimen and its very shy offsetting. It was give...

Yes some of the largest Echinocereus flowers (4 inches to 5 inches diameter if I remember correctly) on fairly thin stems. I once had it in the middle bed in the greenhouse and it spread. A poor picture as it was just a quick snatched record shot at the time as since it was bedded in I could not mov...

I looked up Photoshop Express for the differences to see if the all the editing is done using your devices memory or using their computers on the Cloud but was not successful? As far as I am aware todays cameras or smartphones would not have enough resources to install and use Photoshop or even the ...

I'm not a frequent smartphone user, but maybe Mike could describe his method? Janine raises the reason people Post Process on computers. Conventional cameras, let alone much more compact smartphones, don't have the same memory capacity to include the same advanced Post Procesing programs as a comput...
