if It’s a problem I’ll upgrade cheers I’ll get the VPD sorted I’ll experiment a bit more in morning before lights out .Dr.meter LX1330B Digital Illuminance/Light Meter, 0-200,000 Lux Luxmeter https://www.amazon.com/dp/B005A0ETXY/ref=cm_sw_r_cp_api_i_kdHzFb53AQJVB
This is the one I use. The one you posted will be just fine though. I like this one because the meter is separate from the Eye which makes it a little easier to read.
VPD is around 9.5 25dec c 66% rhBiggest thing is get that humidity down some.
Ok cool thanks for the charts have but them on file and will print out for my grow room downstairs , the chart I’m using has had me pretty close but I’ll get my VPD better sorted with these charts . Always learning always thankful to the Farm community. OdThat equates to 77f with a RH of 66%. That’s ok for seedlings and unrooted clones but that’s about it. You’re at 0.9 kpa which is really low. Meaning your plants aren’t perspiring enough to carry immobile/micro nutrients throughout the plant.
You want to be at 1.5-1.9 for flowering. Here’s the chart you should use as there are ones for seedlings, veg and flowering.
VPD Charts in Fahrenheit and Celsius With Leaf Temperature
We made some easy-to-use VPD charts for both Celsius and Fahrenheit, for clone, veg, and flower stages. Hope you find them useful. For more information about VPD check out our VPD Guide.

I wouldnt air layer just take cuttings to make clones from it’s very easy as long as the diameter of the plant material stem is over 1/8 “ or 3 to 5 mm . Od
No worries mate I’ve cloned for many years and once your up n running it’s a breeze . Thanks for tagging along and for your support have fun growing keep us posted Cobba .Much thanks for this pointer, OneDrop. Neve tried traditional clone making before, but I've seen lots of pictures, and might just give it a go this time around. Done lots of air layering with non-cannabis plants, and my success with those other plant species led me to think air layering would work just as well with cannabis.
Now to wait until the stem grows thick enough. Your response here is much appreciated, and I'm tagging along for the ride with this amazing grow of yours.

It’s in deg C . Od .I seen one drops pic of the surface soil temp of 17. 65 deg F in soil is ok? If so why? How? I slways thought 70ish for better P absorption
Which is 65 or so in F. Wont that limit P intake?It’s in deg C . Od .
Yes a little but I’m not growing for anyone but myself and wife so no big deal it temp is warming up as spring kicke in I’m figuring it will increase which will help the P uptake , may have to get the oil heater in there again keep the space lungs a little warmer . It’s hard in my neck of the woods I’m on a island and have varied weather patterns I must say it’s tring to say the least . Od .Which is 65 or so in F. Wont that limit P intake?
Growing!!!27/9/20 Quick update it's been a battle but I think I'm winning I took a week of flushing to get the ppm down so there a little bit over watered but there drying out have up the heating in grow space lungs spring isn't getting a leg up on the winter as yet had snow on mountain again , I'm still in there swinging . SF 2000 doing great plenty of coverage I'm at 100% 22" above the canopy my vpd has been a bit up n down it's just what it is . This grow is sponsored by @SpiderFarmerLED & @One drop . Cheers for the butchers hook .
They are it's just been a very cold winter down here even with extra heating , the light is running great the external dimmers are great to help control my vpd . The second light is running over the last of a clone crop I'm running seems to be doing a great job . Od .Growing!!!
