One more question, on my lighting set up (2) HLG 320 watt QB288 Rspec slate 2 triple combos that I plan on running a 4'x4' tent, I checked the wattage at the wall with a kil-o-watt meter & one is pulling 288 watts & the other is at 278 watts, I haven't made any adjustments to them yet. From what I have read I should need 30 watts per square ft for the 4x4 which is 480 watts. Should I dial each one down to 240 watts each to give me the 480 watts needed for the area or run them maxed out ?
Guidelines for lighting intensity are real and important but just guidelines. Understand more light is more bud and more potency so no, you dont limit what you COULD use.
Before going further use that Kmeter and tell us what power supplies you are using. You should be able to get close to 320 watts per in that setup, not just say 280. There will be voltage and current or dimmer settings to fix this (easy).
You want a lux meter, the orange one from dr meter works great and easy. This eliminates guessing.
You want at least 2 places in tent to read temps to insure your airflow is good.
Humidity is created or removed in 2 places...you can add a humidifier to the room or the tent, and you could dehumidify but most likely only in the room, the tent is small and a dehumidifier would heat the tent.
So think beyond the tent to the room...you control the room you control the tent. You control just the tent the room will limit what you can control. So if humidity cant get under 55% in the tent during flower due to your environment...you get the room down to say 40 or 45% and boom your tent can be what you want. Airflows from your room to the tent to somewhere...think through the entire flow. Now you see where u put the tent MATTERS a lot!
I have QBs, finishing first grow, i have cloudline exhausts, lots of fans, and have read every newbie guide and tutorial in existence (lol). Ask anything I have good newbie answers having found many myself.
Dont try to overautomate the environment in your first grow. You need to observe and read the plants and see how the room, tent and plants interact. You will likely tweak the environment daily or several times a day. Would you rather be sure it is good by checking frequently or find the plants fried because the automation didnt work as planned! Fancy isnt important...easy is not important...results and learning are imo.
