Hello All! This is my first post and first grow (of my own).

I was mentored almost a decade ago but figured now that I have the funds why not do it for a hobby.




First off, I am a medical patient and currently working within my states limit. I live in the NW and figured with our current cold weather I could get away with 3x600 in a 4x8 tent with enough exhaust and intake from the cold air outside (no AC hoods).


 

I cracked my seeds almost 4 weeks ago and sprouted 3 weeks ago under my 30k lumen 4foot 6bulb T5 HO. The plants were recently transplanted to 5g buckets and upped to full dose veg cycle nutes. They have been feeding on Advanced Nutrients Sensi Grow A and B, with B52 and Voodoo Juice all at 2ml per liter for the first week and now 4ml per liter.


 

Testing has show my tent to get as hot as 79 degrees with all 3 600w HPS on 100% and 75 degrees with all 3 MH on 100% with my exhaust on full. I can dim the middle bulb or add a MH to the HPS line for flowering to help keep temps proper.

 

The current problem is not being able to keep enough humidity in the tent!

 

I realized I could spray down the walls, use 2 small humidifiers and 2 large shallow trays filled with water to allow evaporation. Using these techniques I was able to bring the humidity to 40% with my exhaust off. Before spraying the walls and using the trays I could not get above 7% humidity with my exhaust on full.

 

After an hour with the exhaust off my temps reach around 84 degrees. At this point my timer on the exhaust kicks on and back off after 30 minutes (still testing this).


 

Thanks for stopping by, and sorry for the long read. According to my teachers so far so good. I will continue to update with pics as the plants progress. Also any good advice is greatly appricated!

Seems I have been able to keep temps in the low 80's with my exhaust completely off. This has allowed me to keep humidity levels around 30% and up. I had to dim my middle ballast to 75% and increase my cold air flow intake. My fan speed controller should be here soon and hopefully make things easier. I still need to spray down the walls often, but my plants seem to be loving things and really taking off. I will post Pics in a few days with growth progress.

Thanks for stopping by!
