I've thought about it too. But it seems that dehumidifiers only take out a small proportion of the moisture present. Leaving windows and doors open here (N.E. Scotland) between September and March would result in rather more ventilation than was intended! Winter humidity is probably my biggest kille...

In the current CactusWorld a mix of a 1:1:1:1 ratio of grit, moler clay (cat litter), perlite and organic matter is suggested, I would personally replace perlite with e.g. pumice or just a bit more of the grit and clay as it is everywhere just not in the pot after a few waterings. Well, as you know...

I'm not sure which formulation of Bug Clear Ultra is being used-there are different active ingredients. Bug Clear Ultra contains acetamiprid, Bug Clear Ultra 2 uses rapeseed oil and pyrethrum as the active ingredients. Brilliant idea, two completely different things with the same name. I'm no exper...

I am gradually repotting my collection of Mesembs into 100% 2-4mm Pumice as my initial trial has been successful. Do any growers using pure Pumice know if Mealy Bugs are less likely to be attracted to Pumice than when potted in JI2? I've seen far far less mealy bugs in my collection since everythin...

I've gone through quite a few of these small sprayers. After going to a pesticide course I saw some much better knapsack sprayers, more pricey, but much better in terms of constant spray pressure, easier to use, sits on your back, more volume and a variety of spray nozzles, extendable lance. I settl...

Isn't one of the differences between the forum seed poll and the BCSS seed distribution one of quantity? I have donated to both, but I recall there is, understandably, a minimum quality required for the BCSS one. And my thanks too to Chris for running the seed pool; I have had many seeds over the l...

It is a shame if the seed pool closes. The society seed list seems to cover plants that are more interesting for the experienced growers. I found the seed pool listed more species that those new to the hobby might want to grow eg Rebutia. So the two sources of seed are complementary. I grow quite a...

Payment csn also be made on the website.

There are small portable air conditioning units- Argos does one for £100 though I've no idea how effective it is. The others seem to be a good bit more expensive.

I haven't tried that, no. Sounds like a good idea.
