when I say dry out a little on top, they aren’t dry by any means the only did grouping is starting to brown off but the whole pot is heavy and wet/damp. I will start to feed daily, I’ve been meaning to for awhile but it’s such a task trying to manage it with life ha. res PH is always set to...

Hey there I have these browning edges and stripes through a lot of my leaves.. It is high and low on the plants. Humidity -55-65% Temperature -15-26c (lights on/off I aim for those,sometimes a little outside them) Medium -coco EC -1.7-2.0 Lighting -3x600W hps Fans/ventilation -All...

Sound good, what temps and RH do you chase?

Perfect, sounds good. What temps lower or higher in the acceptable range more likely to give a nice non airy bud? I’ve just recently pulled my temps lower (23) from 25-27 seeing if this will create a nicer bud along with other things amended

Okay thank you. Mine is around there

Pulse One Smart Environmental Monitor this what I need? Or the equivalent?

Sorry, I don’t know quite how to explain it. You know how you test EC with probes. How do you test for VDP? Is there some monitor? Also How do you bring it up or down? Via temp and RH?

How do you actually find the data within your grow though? What is the tool called?

I’m running temps of 23.. how do you find VDP (kPa?)

I have just switched over to LEDs. Just wondering, do you want the tent a little warmer with them over HPS etc? I was running 23-25 with HPS but have heard with LEDs you should have it warmer?

damn mine are all over the shop, 200-1000.

What ppfd should I be after at the canopy?

I can’t seem to find an LED that will cover 2mx2m.. all they seem to cover is 1.5m max… do you think I’ll need something else alongside this?

Can you post a photo of bar LED? I know next to nothing about them. Also, what watt of the equivalent would I need in that size tent to be sufficient?

interesting, if that’s the case. What would you recommend putting in there? For the most even coverage for 14 plants/watts. Could be open to LED options too.. could you recommend a HID option that would be best then LED 2mx2mx2m area.

have thermometer sitting at canopy level

That’s fair chat too. I’ll go grab some 400w hps.. then I’ll just dim the ballast back to 400w

Growing in 95% of it.. only thing I can think it would be foxtailing for would be heat stress?? It never gets above 28c but on occasion may have?? So if I bring the 3 hps down to 400w instead of 600w I’ll have much more play with temps. I’ll run 23 lights on and 19-20 off. Reckon it’s a starting...

Thanks everyone for the help

For sure, I don’t believe I had that issue.. don’t think I have any light leaks either but something to look into..
