two 1000 watt lights gives you about 5,000 lumens per square foot. three gives you 7,500 lumens per square foot. the recommended light is 7,000 - 10,000 lumens per square foot. so, yea i'd say go with three.
it boils down to getting the biggest light that you can cool in that small of a space. a cooltube or aircooled hood would be mandatory with a fan exhausting in open air. a portable ac would be another option. if you don't want all that hassle, stick with the t5 but the results would be...
my rule of thumb is 3 sq ft per plant so a 6ft x 6 ft area would be perfect. whichever light you chose you are going to need to ventilate it, preferably with a air cooled hood or cooltube.
why not two growing areas? you can have a crop every two weeks instead of waiting 4 - 5 months for a single grow.
1000 watts is not overkill for 12 plants. that gives you about 4,000 lumens per square ft which is actually on the low side for light.
a typical set up for you would be to get the bigger tent for flowering and then divide the small tent into top and bottom halves. keep the mother in one half and clones for the other half. then you would veg the clones for about 4 weeks. flowering time is determined by plant genetics and is...
yield is determined by so many different things that an estimate is kind of meaningless. that said, if you do everything right for four months you could get an ounce or two in that space. if you get more space and more lighting, then you can get several ounces per plant if everything goes well...
well, since you asked...your tent is 16"x16"x78" ? that thing is designed for growing one plant at a time. you don't have nearly enough room for plants from all your seeds.
and there are better choices for fertilizers that are made for weed. basically you want anything with a reasonably high...
think of it this way. if you grow all 6 plants under the 400 watt light you might average something like one ounce per plant. if you grew them under a 600 watt light you might get 2 ounces per plant. if you grew them under a 1000 watt light you might get 4 ounces per plant. lights are the most...
you are going to have fresh air issues no matter what and you are going to have heat issues if it gets at all hot where you live in the summer. you can deal with the fresh air problem by adding co2. but you would still need to find some way to get hot, stale air out of the room.
1. no. each plant takes about 3 square feet of ground space which leaves you at 2,500 lumens per square foot (47,000/(3x6)). the absolute minimum light for weed is 3,000 lumens per square foot and the recommended range is 7,000 - 10,000 lumens per square foot.
2. with the propane-based system...
it depends on how good the ventilation of the whole house is and whether you can get enough air exchange between your grow room and the rest of the house. the best case scenario would be if you have whole house a/c with a vent in or near the grow room. you may have to put a vent in the door or...
