The humidity in Afghanistan tomorrow at mid day in 34c temps is 12percent. But where the best sativa comes from in Kerala it's 30c and 70percent humidity.

I read your previous reply, this chart is a better example but for full cycle not just flower although it still fails to appreciate low humidity growers. What is my vpd when I hit 32c and 30percent humidity? This is a common situation for agriculture in warm climates. Tomatoes and cucumbers...

Your chart says on a hot dry day every marijuana plant dies or suffers badly, rather than I educate you why don't you educate me and explain why this dosent ever happen? The answer is it can draw enough water but I'll be interested to hear your version. The upper and lower transpiration...

Google hemp data, there's a whole decade of study on transpirational thresholds and water availability. It's upto you to learn yourself.

Brown weed contains the wrong end product, it's taste is lacking replaced by another. The oil is unaffected still makes good hash. Green is the best overall. You can cure your extracts, no trick just let time slowly work it's chemistry in low moisture environment. Why cure and age are the same...

I recently checked the transpiration limits of marijuana and it's well above 1.7 so not sure your advice is accurate and might want to look into it properly as those charts are full of shit. Only when the plant is water starved would 1.7 be a problem.

Could have topped them or trained, possible option if it happens again.

I'm referring to your first post as well - To us curing and ageing are the same thing and interchangable, just how it happens to be due to it being the same process for this plant. We don't smoke chlorophyll we smoke it's byproducts - enzymes again. Any small change makes different enzyme...

So all this time we're waiting for leaves to grow back you could have just flipped earlier and not run out of room and done more grows in the same time you take to do one. Plus one for defoliating.

Bud turning brown except by extreme lengths of time is not a good thing. Tobacco has different chemistry which makes it brown when drying. For bud to turn brown bad bacterias and enzymes would have to be at play to degrade the green stuff into other byproducts off from its normal path of degrading.

I looks like some noob came up with the product because he had crumble weed and still couldn't grow well. I bet after using silica gel packs and failing his Google search led him straight to cigars. Not realising that is a totally different plant he applied the same principle and found his bud...

Come back to me when you work out the transpiration threshold of different plants. Until then I've given facts and figures from studies thanks!

Keep growing they will get better as you do, there's a lot of stress on your pictures and autos are the least forgiving especially in flowering.

Wondering if you read what I said about VPD? Where was I saying it isn't a thing? Basically saying most of these charts and growers are not describing VpD in relationship to marijuana's transpiration threshold. Are you after a real conversation or not?

I never seen anyone mention the data on hemp transpiration thresholds, very keen to thrust a chart saying I need between 0.6 and 1.1 but hemp can go up to above 2.0 because it can transpire fast. That's the simple answer to stop making an industry based on buzzwords and people not suited to...

I grow as low as 30%, there is no slowing of growth rate more like a faster rate, check the stem of your plant, looks like big hose lines running up the stem to the leaves, water it then cut the stem of and watch water form droplets quickly. The plant is designed to supply a lot of water to its...

It's a common fact that lower humidity encourages the plant to drink more and if that more is present you will not suffer at low humidity or even loose yeilds. Where that chart starts to make sense is when your low in water, the plant cannot bring enough water to compensate the pressure needed...

No I've not noticed even side by side the same strains. Autos lie, some banks put correct times and no quicker than 12 weeks 80/85 days. I think Dutch Passion had a good write up last time I was there about it.

An old assesment but how could the physics and real life situation be any different to this based on what we know about basic leaf temp so far; The use of LED technology is commonly assumed to result in significantly cooler leaf temperatures than high pressure sodium technology. To evaluate...

The optimum temperature is a discussion not a figure. You could vary humidity to vary the cooling rate. Plants are clever, they reflect a lot of unwanted and how about the shaded, underside and stem temps. I would like to say it's the air temperature minus it's cooling effect from water loss...
