Hi all,
I'm a noob and on the first grow. It's been a great journey so far. Can't believe how much I love it! I'm amazed at how much there is to learn and constantly checking what info I'm using is right and relevant for me.
I recently got 2 x Quantum 480 watt boards with no IR or UV just the 600 nm diodes. They are Bright!!!!
I was following old school HID guides for temp and Humidity. I was growing with 2 x HID 400's and one small 250 HPS while waiting for the LED's to arrive. It's far brighter but not much less power usage.
Recently I came across VPD. I've been referring to the the https://docs.google.com/spreadsheet...q_6Mkpd3yJwedSZ3kfxuK0ZVI/edit#gid=1898379675
I've been following some tips from spectrum king vids which have been interesting.
Currently my simple smart humidity and temp sensor is saying 27 C and 70 humidity. Giving me a VPD of 1.3 - I was previously at a higher Humidity but was concerned about being too hot and and humid when referring to tips from grower without LED's. According to the chart increased Humidity will bring me back to VPD of 1 which I believe is to be the ideal for veg for LED? I've been searching for some solid referneces but seeing these boards are pretty new... Maybe that's why it's hard to find.
I've got an infrared laser gun coming to measure the leaves and parts of the tent to fine tune but love to know what works with these lights if anyone is able to chime in. Not having IR and UV atm (may look for some additional bulbs that can add that spectrum soon. But no IR means less heat.
Any tips on what to use for additional IR and UV? I may be getting a loan of an HMS to throw in during flowering. I opted to not have the IR and UV diodes added as they seemed more of a gimmick, especially the UV ones. I worked with UV photography and you need a lot for it do anything. Whether the small amount of UV from 8 diodes would add something is yet to be proven.
So currenlty what are people finding with these Boards? What's a good VPD, temp and Humidity for Veg and for flower? What leaf temp can I have and do I use that to determine how close I can have the lights to the canopy?
I'm doing a DTW, in coco and perlite and it's in a 4 x 8 tent. Watering with halo's every 3 hrs.
I'm not using C02 atm but am pumping in a heap of clean air into the room that houses the tent. Need to invest into a good c02 meter next grow....
I'm organising dehumidifiers atm to help control the humidity, especially for the flower stage. Borrowing a unit to dry the main room to see what that does but thinking I'll just get small quite unit in the tent as I'm after a quite environment once dialed in.
Cheers!!!!
