I'm a first time poster and a first time indoor grower. I have done a lot of reading that I've reached to a point where things are getting messy in my head. This might be a long post but please put in your replies as accurate as possible. I do have a medical case and its the simple insomnia but you think it just sounds that simple. anyways..
I will be posting my grow room dimensions which will be a small closet that I have built just very close to my bedroom. (see map below). I have chosen to use LED lights for various reasons. My grow room is the balcony extension of my bedroom which I closed externally with aluminum windows and will install a closet of 278W x 260H x 70D. Why I have picked LEDs: In my country we don't get electricity 24/7 from the government which means we have to "rent" 5 amps of electricity from a shared generator in the area. 5 amps means anything more than a fridge/TV some lamps will cause the breaker to cut. So using power hungry lamps like HPS with the ballasts and possible cooling fans/ac is out of the question. I also dont want to use the HPS lamps just because the grow room is very close to my bedroom and i don't want to be sleeping near the sound of fans and unhealthy gases that the Hps may emit.
Now, I know the LED is not proven with many and others may endorse it, but I have made up my mind. Having stumbled upon the grow lights called Grow Pro 400 (selective switch) which are relatively affordable for my budget. The help I need from the forum members and possible LED experienced growers is whether the Pro Grow400 that produces 240w in full illumination mode will be enough for my grow room of 278W x 260H x 70D having 4 plants.
- Has anyone used GrowPro? - Will one light of 240 w be enough for 4 plants placed next to each other as drawn in the map?
Technical Specifications
Power Consumption - 240W (full illumination mode) Effective Coverage Area - 2.3m2 (25.0sq.ft) Operating Temperature -20°C ~ 40°C (-4°F ~ +104°F)
Some of the questions that you ask are subjective but I will give my opinions and let other people debate other opinions.
You'll have to forgive me but I don't do metric so I'll assume that the "map" is to scale and that the grow pots are not giant. I'd say that no, a 240w light will not work with 4 plants in that position unless they were flowered VERY VERY small. 2 rows of 2 would give enough room for 4 larger plants with a 240w light, assuming that you don't let them get too big and assuming that the closet can handle approximately a 4 or 5 square foot area. Even in this configuration you would need to start flowering at about 12-14 inches tall or they will get too big for that light. Also you may not need the table to elevate them while in flower either.
The HPS is safe to be near (gas wise) but you could damage your eyes and skin. Same with LED. A 240w LED will put out less heat and in your area that might be a good thing. Can you not grow outside anywhere and use no electricity?
Also, while I have never looked at that light, the specifications you post are very exaggeratted. There is no way possible for any 240w LED light to cover 25 sq.ft You would need 5 times that amount to grow top quality medical plants in 25 sqft, in my opinion.
Hope that helps...
