There's still a long way to go until flower but if I may suggest you start looking for a source of calcium, because under modern lights calcium consumption goes way up and you're going to have to prepare your soil for it or use a Calmag product which brings its own problems in soil (excess nitrogen, chelated products not ideal for soil growing).

I personally add 5g/L of dolomite lime to the soil mix for the last repot before going into flower, just to give you a suggestion.

LIttle discussion about calcium deficiency over at greencalyx's Deep Chunk thread. I didn't know this. So it must be light spectrum causing more calcium consumption during growth?

vapor deficit pressure is likely too high . v.d.p related. the spectrum is fine, maybe lacking radiant heat .. if led grown, likely low heat and high pressure. but essentially is v.d.p related. research it , v.d.p indoor growing


it could be a calcium and mag issue if the base nutrient they are using isn't supplying these elements . if they are using complete base nutrients then the room is not dialled in for the strain

I see, cool, its just a way to correlate temperature and humidity into one value. VDP is used to determine the amount of excess transpiration due to dry conditions or fungal promoting conditions due to high humidity.

My textbook on plant propagation doesn't mention VDP although it discusses temperature and relative humidity separately.

Lets talk Vapor pressure deficit (VPD) in cannabis?

As the title says, how close is this chart? And is this what we should all be aiming for. For a perfect environment? Anyone here specialised on this subject that could give me and others a more in-depth knowledge about the subject. Thanks Green :tiphat:

DLI = Daily Light Integral - total amount of light over the entire day

VPD = Vapor Pressure Deficit (or differential?) - it's a more complex thing related to temperature and relative humidity and how the plant transpires moisture based on these conditions. There's a thread about it here:

Funnily enough revisiting those charts seems to show that dry air and cool temps are actually pretty good. Cool temps slow everything down though so I wonder what these cool temp VPD sweet spots achieve.

Thats a good question, running the plants at cooler temps., at the sweet spot VDP at least in short periods during flower, could get better terpene production.

I always find the plant sweeten up after cold weather. I think the resin changes a little after summer turns to fall.

Oh yeah, lots going on, only God knows it all. We study the thing and end up with more questions than when we started.

The vapor deficit pressure it sounds like describes transpiration water vapor potential of the leaf. Less transpiration due to low RH/VDP and this will cause a slowdown of mass flow, slowing the uptake of heavy mineral cations such as CA+ and MG+.

Still looking into, it but from what I can tell, thats what VDP is for. Wonder if thats new. Will have to look at the plant phsysiology textbook.

I take a bite and shake the shaker over my mouth! Sooo good.
