First ever grow, so bear with me.


Room stats:
60"L x 23"W x 74"H (Floor to top light, additional 24” freespace above the light)
Floor and 1 sidewall concrete, consistent 60ish degrees F
Two walls 1/2" drywall, entry door is white tarp
Space is narrow, long, tall, and will be cool year round. Heat from lights will not be a problem.
Room is isolated, building is isolated, smell and noise are not an issue.


Lighting stats:
400W Metal Halide for entire grow/bloom and
3ea: T5 46" Fixtures, each with 4 bulbs
For 18/6 seedlings: (6) 3500K bulbs, (6) 6500K bulbs, no MH
For 18/6 grow period: (12) 6500K bulbs + 400W MH
For 12/12 flower period: (12) 3500K bulbs + 400W MH
Digital power strip/timer for the lights
It is bright as SHIT in here when all lights are pumping and the room is sealed up. Might have to wear sunscreen when watering the girls.


Grow stats etc:
Soil: Scotts
Nutes: Hesi Soil
Seeds: (10) KC Brains Spontanica, (5) G13 Power Skunk
Homemade adjustable shelf unit to adjust for plant height, keeping plants at ~20" from lights
Vornado 10” fan for air circulation
800W ceramic heater to keep temps above 70 degrees F, humidifier undecided

Questions:
1.) Is this enough/too much light for <15 plants? I've got another 400W MH and (4) T5 4-bulb units available, will adding them aid in anyway?
2.) Along those lines, will adding additional T5 units down the wall aid in anyway? If so, what bulbs should I use?
3.) Is it possible to burn lower leafs with too much light?
Take a look at the pics, let me know what you think.

you can and should add the t5's down the side of the wall, too much light is only too much if the room temps go up and/or the plants start touch the lights.... only way they can burn. especially with t5's u can get pretty much 1/4 inch away without burning

im not an expert but as far as i know u can never have to many lights. as long as the mh arent close enought to burn the plants. side lights will help the growth by giving light to the leaves that the top lights cant get to. the T5 can be placed close to the plant like 2-3 inches. good luck with ur grow.
