hey i was wandering your opinion or anybodys im ordering seeds and starting my first indoor grow. i grew outside they were like 1.5 feet tall by 1.5 feet wide and deer ate them. what light should i use. 400 w or 1000 w or does it not matter
it definitely matters, with a 1000w you would have more than double the watts than with a 400w, that's a given. With a 1000 you could have a much larger crop, say, a space about 6x6. with a 400w you are limited to about 3x3. Based on what kind of bulb you have, ventilation, and cooling unit, this will determine how close you can the light to plants without burning them up. More light = larger yield.
Basically the short and simple of it is there is a basic rule of thumb. 1watt = 1 Gram.
Hope this helps.
