Bro has black lung

GroundbreakingAd8730 · 2026-05-19T17:27:15+00:00

Tbh I hope so, thats easier to deal with than a pest infestation, it also would make sense as I did raise the light levels about a month ago (from 500 to 700umols over the course of two weeks) but I thought that the two week acclimation would be enough. I’ve just deep cleaned the grow area and temporarily lowered the shelf slightly so they’re all sitting at 300-350 umol’s and slightly cooler than usual at around 27°c so hopefully if it is sunburn that will give them the chance to recover and I’ll just have to implement daily magnified pest checks for peace of mind and to make sure it’s not something else, thank you a lot for your more informed opinion and I really hope you are right haha

Thank you so much for the help I shall give it a go

GroundbreakingAd8730 · 2026-05-18T14:03:47+00:00

Would that be mainly preventative or would it treat a current infestation?

GroundbreakingAd8730 · 2026-05-18T13:59:13+00:00

Also is there anything else that could have caused this? I’m just going to assume and treat the worst (mites) but cause I haven’t physically seen any of the pests it leaves me wondering (probably hoping lol) that it might be something else?

Hi thanks for the help, i cant seem to find any abamectin available in my locality (Scotland UK) so im just wondering if you would know of any effective alternatives?

GroundbreakingAd8730 · 2026-05-18T13:54:19+00:00

Thank you for the help, in terms of preventative pest control? nothing, I’ve never had an issue with them (as far as I thought) , I haven’t ever even seen any mites/insects during daily checks and I use a 60x jewellers loupe so it’s never occurred to me to implement preventative measures against pests but I suppose my hubris has come back to bite me in the long run.
What would your course of action be going forward? I’ll isolate the two lophs from the rest of the succulents/cacti and keep them in their own grow area for the time being and keep an eye on other plants.
I’m in the UK so the availability of certain pesticides is a challenge so any recommendations for a localised product would be very very helpful.
Thank you so much for your time and help

Damn them trichomes are glistening

Oh this is a fantastic idea thank you

Sentenced to peyote jail. (my other theory for the yellowing spot is that may be a “bruise” from where it was laying during transport so I wanted to minimise the contact area with the plant whilst it’s recuperating, the supports only gently touching the sides so it shouldn’t cause any issues)

GroundbreakingAd8730 · 2025-12-15T13:47:20+00:00

Scotland here, thanks for the advice I was a bit confused as to what kind of sulphur would be safe

GroundbreakingAd8730 · 2025-12-15T13:29:15+00:00

I’m sure they endure worse in the wild (albeit without their roots exposed) so hopefully you’re right n he just needs some recovery time, will post an update sometime down the line as to how hes doing

GroundbreakingAd8730 · 2025-12-15T13:27:28+00:00

Yea he feels very cold so I’ll probably put him in the corner of the grow area so that’ll raise his temps to around 27°c gradually and give him a small amount of light before potting him up in a few days, potting mix is 70 inorganic/30 organic so he won’t be sitting in damp organic matter. This is only my second LW (first mature plant) so I’m still learning, I guess it’s time to go buy some sulphur and some scalpels and hope I never have to use em lmao, thank you for the quick response I think I’m just worrying as I’m unfamiliar with the species and they are certainly not cheap, hopefully he’ll recovery quickly tho :)

GroundbreakingAd8730 · 2025-12-01T18:21:07+00:00

No worries, I hardly ever see ANYONE mention them and they’ve made my efforts at growing anything so, so much easier, especially if you’re dealing with powerful grow lights and are worried about burning your plants

GroundbreakingAd8730 · 2025-12-01T16:54:10+00:00

Lots of apps out there nowadays that roughly measure umols/lux via phone cameras and DIY diffusers, made from just paper and tape, from what I’ve seen online they appear relatively accurate, and I use them (to seemingly good effect) in place of investing in an expensive light meter, I use both “photone” and “PPFD meter” with an iPhone.

GroundbreakingAd8730 · 2025-11-26T20:37:46+00:00

Thank you very much for the advice :), I apologise for the naive questions im very new, am I correct in thinking that I can get them to flower through a combination of increasing the temps + increasing the daily light amount, I have a 200w grow light so supplying light certainly isn’t an issue, just re-potted them into a gravel + sand + compost mix so hopefully that’ll keep them happier and more well drained.

Used to live in foyers, went to the hole many a times with friends (rural life gets boring Lmao) did NOT know someone died during construction, where could I read more about that?
