Will rearing from seed negate this issue?

So at what temperature is HPLVD treatment done dose anyone know? Most plants are treated at 35-43c for 4-6 weeks for virus infections. Although I can find success stories of treated cannabis plant's I can't seem to find a definitive temperature. I mean hopefully I never need to treat a plant but its useful information to have just incase

@brock1 you're not saving a hlvd infected plant if that's what you're asking?  Even tissue culture isn't guaranteed to be clear.

Thats not what I am asking. What I am asking is this. Lets say you have a mother thats 30yr old. Now you suddenly get HLVD & your the only person who keep this clone at current time. To clean the clone you need to culture it apparently.  I say apparently because I don't believe that part for 1 second. A clean clone in a clean environment in rock wool would be adequate for most plant imoa. Not to remove the virus from this previous clone it need to be kept at a higher temperature. Normally 35-43c for 4-6 day. Just like humans keep warm plenty of fluids to stop dehydration to kill a virus because they don't like heat. So what I am asking is the upper end heat more important than the duration of treatment or the duration more important than the heat in treatment of HLVD?  Lets face the facts most people I know that could get this would ether bin the sick plant or dump it somewhere away from their grow causing its spread. So were going to see it more frequently. Personally I would rather treat it than start again with someone else's selections ect.

The only heat treatment id use for hplvd requires a can of ronson and some swan vestas...

@brock1 sorry mate I still don't understand what you're asking.  What do you mean by 'treat', what are you trying to achieve?

 

Hlvd is a viroid also, not a virus.  There's no protein coating on the rna and molecules are smaller and more mobile.

 

Are you asking how to dispose of infected plants?

I am not sure I can post the links here but here's a copy & paste of what I am asking. Hope this helps?

 

The best way to control the spread of HLVd is to get rid of infected plants as soon as HLVd is detected. If this is not an option (because you want to save the stock plant, for example) viruses and viroids can generally be eliminated through heat and cold treatments of meristem via tissue culture.6 Nov 2019

This I would have to see, is that even possible? Off topic but what's the longest non flowered mother you could keep?

Ot1 would talk about bonsai mums being kept over a multi decade timeframe as long as there was proper care and maintenance.

Gooey mother is from the 60's. A Thai if I remember correctly but he talks about it in his podcast. I had it & its exactlyas he says. The G13 used to make mr nice was over 30yr old. I have a NL cross here from the early 90's. Cheese will be around 30yr old by now. The biggest factor seems to be light. Even with all the fancy new light everyone i know who as old cut as to put them in sunlight to keep them healthy.

Sorry bit off topic. @brock1 when you say put them out in sunlight, do you mean for a few hours each day, or will you actually leave it outside for a long period? Also what do you do to stop bringing pests in when she comes back inside?

I will run them all summer outdoor. Around July August I will take a new cutting to be a new indoor mother. I have cleaned them a number of ways over their years from peroxide, chilli & garlic spray, need oils or just a general bug spray like bug clear. You don't need to put them out every year around once every 3yr seems to be just fine.

I got ya. A few new cuts are a lot easier to clean than a big mother would be, makes sense now! Cheers Brock
