Hey guys i just had a few questions that i was hoping you guys could help me out with. I am planning to start a grow using a 4 foot wide 8 foot long 6.5 foot tall grow tent or a 6x6x6.5 grow tent. I will be using a 1000 watt HPS air cooled light and then adding a second after my first grow. Which of these tents would be best in your opinions for best light coverage and access? I am really hoping in the future to achieve 1 gram per watt but as this is my first grow i know it is highly unlikely. I figure i might as well get all the info i can to make sure i am on the right track to achieving this goal. I am planning on growing 4 plants to the size of 12 inch's and flowering under one of the lights, is this height and this amount of plants per light adequate? As i said i am just trying to make sure i am on the correct path to yielding one gram per watt so i figure i better make sure i am starting out the correct way. As far as ventilation goes i am planning on using the 6 inch Vortex 449 CFM Blower but money is tight at the moment so i am trying to figure out what exactly i can get away with. I hope to be able to vent only the lights so i can leave the room sealed for co2. I just need to know how many CFMS i need to exhaust 1 or 2 1000 watt HPS straight threw the tent? I know the vortex would be the best because i am pretty sure it could handle the job and i could turn it down to the level i needed it, but as i said i am on a budget. I also realize that humidity issues may require me to vent the tent, but if so i can always throw on a carbon scrubber and pick up a smaller $30 booster fan from eBay or home depot. I am taking Rumbles advice and going with Vic super soil for my first grow or two just to learn the basics and for mediums for my mothers. I have a few bubble buckets laying around and i would rather start with bubble buckets but i figure i should probably go with this for my first grow. Anyways i will be using this recipe and i would like to know approximately how many gallons of soil i will come up with? And i just wanted to make sure that it is safe to use this from seed? i would also like to know how much i should moisten it? 1 Bale sunshine mix #2 or promix (3.8 cu ft) 8 cups Bone Meal - phosphorus source 4 cups Blood Meal - nitrogen source 1 1/3 cups Epsom salts - magnesium source 3-4 cups dolomite lime -calcium source & pH buffering 4 cups kelp meal. 9kg (25 lbs) bag pure worm castings - Mix thoroughly, moisten, and let sit (uncovered) 1-2 weeks before use. I am also considering starting early with nematodes as preventive measures against bug attacks seems like soil growers have problems with this. Anyways what do you guys think? Sorry this was so long and rambling but i would really appreciate any help you guys could offer up?
