How long does soil take compared to hydro?

does anyone here actually own a lumen meter? buy one, you'll learn a lot.

No I dont have one

But they dont add, not exactly anyways.

Lets say you have 2 white circles. Both same size, same whiteness. Does having them next to eachother make them more white? No. It just makes twice as much surface area the SAME whiteness

Wrong, please stop mis-information people.

The reason folks add light is to cover more square footage.

Do some research, you'll learn something today!

ahhh you are a idiot and a mean one lumens dont add moronj you do the research. they overlap example 2 100 watt cfl's put in the space only usually occupied by 1 your only giving the lumens of the 1 bulb the other is a useless draw of power. man read a little people geeze

They don't add period. But wha you believe won't bother me one bit

Peace - OGH

Hehe, this is fun, they don't add. Where's the ignore button?

how is it that when you buy a 4 bulb floro light with 4 bulbs that are ONLY 5000 lums each ... they advertise the light as a 20000 lums light??? what say ye???

was i late or what

If you have 3 apples [lumens] and someone gives you 2 more apples [lumens] how many apples do you have?
Of course lumens add... why else would people use more than one light?!?!

As to the main question: It depends on how big you want your plant to get. It will continue to grow as long as it has space, food and light. If you are doing a small personal grow, let it veg about a month to 6 weeks then let it flower til its ready (depending on the strain).

he's right, lumens don't add up.. if you have 4 3000 lumen bulbs, you don't have 12k lumens, you havre 4 3000 lumens.. for instance, you're not going to get the same lumen output form 4 3000 lumens bulbs, which are probably about 23 watts each, as you would from one 250 watt'er which is probably about 25k or so lumens.. you still only got 4 bulbs, each of which are only 4k each.. i know it's a bit confusing..

but as far as how fast is hydro vs soil. there really is no difference between the two.. hydro you get bigger growth faster in veg, but it still takes a 10 week strain 10 weeks to flower regardless of medium.. the plants might be bigger in a hydro setup vs a soil run, but they will still take the same amount of weeks to finish..
