Starting first grow, buying the girls tomorrow... 5x5 tent 2xhlg550s INSULTS WANTED

Hey guys, I am starting my very first grow. My grow setup consists of a 5x5 gorilla tent with a 8' ceiling and 2 HLG 550 lights. For ventilation I have a 350 CFM AC Infiniti cloudline t6 with no filter currently. I have a used Can-Lite filter that is 40"x12" but do not know any history behind it and am timid to use it. I have setup my reverse osmosis filter (stealth RO150) close by and am getting a reading of 5.3 for PH and 0 for PPM, out of the tap the water is around 7 for PH and 45 for PPM. I do have PH up and down. These readings were done on old Bluelab pens, I will be replacing these eventually but they still read the calibration solution just fine. I just did a stress test in the tent at 750watts at the wall (375watts a piece) and recorded a temperature of 87. I plan on vegging at around 400watts. 87 degrees is a little higher than I like but I plan on taking the two Meanwell HLG480h-2100As out of the tent. I am not sure how much this will lower the temp but it should be something. Ambient air temperature was around 76 when testing.The room the tent is in is a 10x10 room with the tent exhausting into the room. I can not vent the tent into the attic because I use the whole house fan often.

Tomorrow before I pick up the clones at RCP in sacramento I was planning to get (4) 7 gallon fabric pots with enough Fox Farm Ocean forest to fill the pots.

My questions are:
1) Is starting with Fox Farms Oceans forest a good idea or should I look for something different?

2) How is the pot size at 7 gallons?

3) Can I use an old filter that I do not know the history on? I have washed the dust cover twice in the washing machine.

4) Is it wise to grow a combination of Indicas and Sativas? I figure the flowering time would just be longer for the sativas and I could harvest the indicas first.

5) The wiring is going to get cleaned up more but does anyone have any suggestions on what I should be doing differently?

6) Should I use a used filter that was from a liquidated grow room?

Thanks in advance

1) Yeah its fine, just play around with it, I personally use a 70/30 coco perlite mix.
2) This depends on how long you veg the plants and with taking into account the flowering stage, so generally the ratio is 1 month veg : 1 gallon so yeah it should be enough for 2 months veg and flower in a coco grow medium however I am unsure with soil.
3) If it works yes, if not dont use it.
4) Generally sativas mature faster than Indicas.Yes it is fine growing them in the same tent just cut down the plants that are ready for harvest by looking at the trichomes and keeping the plants that are not ripe for harvest in the tent for longer till the trichomes indicate otherwise.
5) The environment looking good, just have fun and alter things that cause problems on the way.
6) If it works yes why not, if it has problems or is broken NO.It all up to you to decide good luck!

Hope this helps and have a fun time growing!

Filters can have spores and biological crap in them. I would want to burn some sulfur and run thru it first, then it would be a great silencer on the inside of your inline. (carbon in the filter may not eliminate odor due to age/usage)
Good luck at rcp, that place is a zoo.
If you go soil, you can do better than Fox Farms imho.

Thanks, will do.

TintEastwood, what do you use for soil?

about a pound .. oh and .. penis (I think I got all the obligatory insults out of the way.. oh wait.. LEDs cant grow sht and flushing is for toilets! ok now got em all)

"2) How is the pot size at 7 gallons?"

Probably too big. I have an 8 foot ceiling in my flower room and most of the pots sit on 12 inch booster seats but I still have plants growing into the light in 3 gallon pots. Try 5 gallons first then consider 3 gallon pots if you have height problems.

Good luck, BigSteve.

Thanks, unfortunately by the time you posted that I already purchased everything. A new thread is to follow with my new girls.
