First time grow room

Hey RIU
Just seeing if I can get some feedback on my room, ive done a lot of research and put a solid 3 days into redoing this room (can check my journal for more pictures). Im still learning so any tips or info can help.

Its a 400w hps light, 6 inch hurricane inline fan, have a circulating fan and a warm mist humidifier. The girls are finishing veg in there since im rebuilding my veg cabnet. They are in diy 5g air pruning pots, 25% worm castings and the rest promix hp. Using the advanced nutes line.

Without the hurricane running temps are 26c and 30% rh, its currently -15c outside. Fan on the temps drop to 19c, havent had a night cycle to check temps but will post once I do.

If I forgot anything ill try and post it later.

You have been busy ....Yo! ...lol, best to do a running analysis over say 7 days..?

Yeah haha had a few days off so what better way to fill my time. A good 2 days full 12hours working and maybe a 3rd day of slacking finishing it off.

As you said I am watching the temps like a hawk over the next week or so (Trying diffrent things like fan speeds, light height, ect.) Ill keep it updated as the days pass and clearly summer will be a diffrent story but it seems to be a nice temp at most times. Thanks for the feedback.

I am looking at updating some of the equipment, electric ballest or something. Any suggestions?

Digtal is a great start ...lol bot Mh & HPS ...http://www.amazon.com/Apollo-Horticulture-Dimmable-Detachable-Reflector/dp/B00547I5I8/ref=pd_sbs_lg_6

Took the words out of my mouth. The shops around these parts carry Ace ballest, indaga or somthing and Real sun. I guess lumatek went under? Aslo upgrading to a 600w i think

Went out today and bought a new digital ballest. New 400w mh bulb and a new 600w hps. For about 300 bucks. Its a 600 digistar Gavita digital ballest, from 300w to 660w. I have hooked it up and the girls are finishing there veg under the mh.

I figure ill spend about the same amount on bills, and the temps should be about the same as well, but this will cut my veg time in half and give me a huge boost in yeild. Heres some pictures, let me know what yah think
