WHITE WIDOW: AUTO PT 2

hey there GeMann, you dont want any more of that tacoing, that looks like max VPD to me , sometimes those QBs are like Xrays they have so much penetration lol anyway hope this helps ! 🚀

I think you should keep it at this intensity. It is tempting to max them out but it can be counter intuitive with autos. As your on a 20 hour light cycle they will be getting enough DLI . I estimate your on about 50 DLI right now. Any higher with a 20 hour light cycle I think you would need extra CO2. Remember you can increase your instensity with photoperiods as they're only getting 12 hrs of light per day . Autos are differnet .

Looks like you need no advice. Looks dialed in to me. Looks awesome.

The VPD charts for cannabis in flower are all skewed in a way to make it “better” to have low humidity . But actually why would that be the case ? Well, it wouldn’t be for any other reason than that low humidity is common practice (to reduce the likelihood of mold) . High humidity in flower as well as in veg is better for the plant perspiration , but all the vpd charts say low humidity. So if you want optimal vpd keep the 1.0 but if you want a safe flowering (and you should!) go with the higher VPD . Hope this helps ! 🚀

Vapour-Pressure Deficit for those playing along at home! Basically about plant transpiration rates and CO2 assimilation. I'm not sure cannabis cultivation needs to be so complicate, VPD is really splitting hairs and I can't see how it could or would affect cannabinoid quality, quantity or synthesis. Anyway, a high VPD is required during flowering. Hope this helps,......... Organoman.

yea every genetic has it's own unique way of ripening on the trichomes.

All plants are different individuals. even if they all came from the same packet and will have their individual schedules and will not grow exactly the same from one harvest to the next. There are too many factors involved with each and every grow that will influence timeframes. Going to 18/6 would be much more plant friendly, anything more the 18 hours of daylight is going to stress any and every type of cannabis plant. It may well cause this/these plants to mature faster, the reduction of light often triggers a hormonal signal within the plant to get moving and hurry up finishing. It is also a good trick to use with stubborn and continuously re-flowering Sativa dominant strains in order to speed up their maturation. Even going to 11/13 with photoperiod Sativas is advisable to hasten maturation, with no drop in quality or yield. So, 18/6 as a max will give you healthier autos, again with no loss of quality or yield. 20 hours of light is just too much for cannabis, and is often recommended by people who don't care about their plants or those who don't understand the basic biology associated with cannabis growth and maturation.
