    I have a question about the difference between traditional clonal propagation and tissue culture

    now if a new cell is born from the meristem of a clone isn't it a proper new cell? does the said new cell before getting is final role have any kind of memory? I personally think that the new meristem cell doesn't have any metabolic or dna/rna (if so pls let me know!) kind of senescence info...

In 2019 around 800 hectars where dedicated to CBD or seeds or biomass all over italy more or less the same surface had been dedicated to cannabis in 2020 only in a region...

    PAR level for seedlings? @300?

    from what I gathered the general numbers are those -seedling 60/100 umoles -veg 300/500 umoles -flower 800/1000 -flower+CO2 around 800/100ppm up to 1500 umoles more that is not useful to the plant, since the light provided energy can be used and stored up to a certain point. even after u set...

    pH Crashes and EC Spikes in DWC - is this the issue?

    could the purple response be a phytocrome response to full spectrum LED? to have better purple expression I used cold temp during light out in the range of 16-18 C between other things... but having such big sway in your reserve could mean P isn't absorbed at the ideal rate...

    pH Crashes and EC Spikes in DWC - is this the issue?

    Any experienced CBD growers?

    it's my understanding that there are 2 kind of trichomes. basal trichomes are the ones resposable for cbd production, I suppose they're shorter than the ones producing thc. I grow a high cbd less than 0.5 thc strain and in about 8 weeks I get to the cloudy trichomes stage.
