Hi guys , first I would like to thank everyone for all of their contributions of experiences and advice being given on this forum. I have learned a great deal over the past few days and decided that I may be able to eventually have a grow of my own. Also in advanced if this is the incorrect place for this thread I apologize. Fortune have it , a very good friend of mine has recently needed to move due to getting a new job. He is currently running a grow that is near harvest ( about 2 weeks ) and will be no longer be able to continue to due space and a lack of free time. Due to this, he has offered to let me borrow as well as help me with starting my own grow. His equipment is currently 2x3x6ft grow tent. a 400watt HID bulb with a ballast of some sort, he is growing using 5 gallon buckets and a hydroponics setup with bubbles is all I know at this point. He has a carbon filter and intake fans along with a 6inch fan for circulation. Again I am still very new and do not know the exact details on specifications on these products but I hope this is enough information to give you guys a good understanding on what I will have at my disposal. My problem is A) I have zero experience with growing anything. 2) From what I have read I will not be able to deal with the amount of heat that the 400W HID bulb puts off effectively. I do not have access to routing the heat away from the plants/closet in my apartment. My go to thought is that going LED would solve this problem and this is where I would like the advice from everyone's wealth of knowledge and experience. I have about 400$ to purchase an LED grow light ( or to invest in this setup in order to make it function effectively for my situation ). Would 400$ even be enough to get a light to properly support a 2x3x6 space and if so , what would the correct number of plants be in order to take advantage of this amount of space. My friend has completed 2 grows now so he is much more experienced than I am and I know that no matter how much a I read and research , there is no replacement for doing it and getting my hands dirty. That being if you guys could help me come up with a better game plan and strategy before I do this I know that I would be much happier and prepared and also have a smaller chance of failure and wasting money. Thanks ahead of time for all of the help and time and I look forward to learning!



P.S. - I know that my friend has averaged about 10.5 ounces from 4 plants over the course of a 3.5 month grow using this equipment. I do now know the particular strain , and I may have no given enough information. But if you could guys could ballpark whether under average conditions if this is a average yield or not that'd be fantastic. Thanks again!
 
:welcome: you chose the best site for info you seek! I wish I could give you tips on LED light choices, but I have no exp. w/ them, you might consider CFL bulbs, they don't run hot like HID/HPS bulbs. My other thought is for you to read the many journals detailing LED & CFL grows. You read read "completed" journals or journals in progress, you will get great member feedback if you ask the right questions. Experience is what will increase your yields per plant, so many options! Best of luck to you!:peace:
 
LED's give off heat. You won't be able to utilize your entire grow space unless you have some place you can exhaust your room to.

Portable AC units (or window AC units converted for "portable" operation) can work... if you have a place to exhaust the heat from the condensing coil to (and can deal with noise in your apartment)... or have a window and can manage the condensation off the evaporator coil since you'd be dripping water outside that'd smell like weed.

Also, you need to circulate the air. Take the volume of your grow space. Good rule of thumb is a well ventilated room will refresh that air AT LEAST once every five minutes. So, 2' x 3' x 6' = 36 cubic feet. 36 cubic feet divided by 5 minutes = 7.2 cubic feet per minute (CFM). That's nothing. The air you'll need to move just to keep temps down will easily be enough to provide adequate ventilation (CO2) to your plants. You can ventilate that with PC fans powered by phone chargers, not to mention the AC unit would move more than that amount of air, but it doesn't solve our issue.

Good rule of thumb is for every square foot of grow space you have you'll want approx 40W of LED covering it (less will work, so will more...). So, 2' x 3' = 6 square feet. 6 square feet multiplied by 40W per square foot = 240W of LED. I'll split that into two lamps in an attempt to get more even canopy coverage. So two 120W panels. Easily done with $400.

But where does the heat go?

Also, not only is it not smart to grow in an apartment due to the many constraints and dangers inherent with it, it's not smart, imo, to grow in any place that you're renting/allowed to live in. You don't own the property.

GL, and stay safe, man.
