Content from a recent email from a European seed-supplier - what will be effectively a ban relates to species/genera that are significant agricultural crops. The only logical way forward would be to bulk-buy as a group of people. Since 1 January 2021 seeds from a couple of “high priority plants” can...

If you search the website there is a thread from a few years back of several posts long about D. r. . Concensus was/is that it is a challenge to grow after it has gone dormant for its first time after germination and is naturally short-lived. So far as nutrients go, there is a pool of wisdom that ma...

I can't find anything online showing it, but you'd only get plantlets form at any scale/node/bract on the scape, which might only be the one flower. I can't see why any would form on straight, clear scape tissue.

Yes, it is patently clear you know what you're talking about. What isn't quite so clear is why you are being so unpleasant - I guess you choose to be that way. You are confused again - unpleasant as opposed to factual. Unpleasant because I point out the flaws in what has become commonly accepted go...

As INK BIRD/Ink Bird/Inkbird claim that they use an NTC (negative temperature coefficient) sensor, that would indicate a thermistor sensor, as opposed to a Pt100 or thermocouple (or, God-forbid, a bimetallic device). Shame that it is stuck inside so much rubbish that it has inevitably become insensi...

Not really - I was heavily involved with BCSS, including articles in the journal unil maybe 15 years ago. Then life went tits-up and I have not rejoined. I know what I am talking about, otherwise I do not talk. Quite simple. So far as heating etc, is concerned, there is an article in past jounals by...

You having a bad day? Not at all - loving this - leading the blind, or at least the very easily led/bamboozled/conned/confused (delete as appropriate). I will say it again - get a cheap thermocouple meter with a bare thermocouple............................ It ain't rocket science, but a lot closer...

Don't bother - just checked online. Inkbirds - a joke - the sensor is encased in mountains of rubbish that produce masses of hysteresis.

Standard max-min alcohol or mercury-in-glass thermometers are rubbish for this sort of thing. Even worse are the saviours of mankind - "digital" thermometers that use a sensor wrapped in layer upon layer of junk. Joe Average has fallen in love with, and been conned by, anything electronic ...

Not caring is costing you money and, potentially, plants, especially with such a very low switching frequency. I do not bet, but am tempted to, that the temperature variation in your greenhouse is a long way different to what you think - the highs are higher and the lows are lower. Being cooler will...
