24 hour light?

[engineeredweed]

Is this bad for the plant? is 18 on 6 off better when veging?

 

[Igotdialup]

I did 24/0, but I think 18/6 would be better.

 

[del66666]

cannabis can only use around 16.5 hours of light per day so go 18-6 in my opinion.

 

[engineeredweed]

decent yield etC?

 

[del66666]

not yet they r still working on it, saw a grow on you tube, wasnt impressed.

 

[engineeredweed]

would this be better?

 

[del66666]

cfl, envirolite,hps light, still got to say no led, dont think they sussed them yet. t5 tubes r ok, t4 tubes work, strapped 4 cash? space only small? how much bud u after producing?

 

[camaro630hp]

cfl's all the way

 

[The sim's Bob Newbie]

I always thought it was 24 hours for the first week or 2 then 18/6 to veg properly before flower?

 

[del66666]

u can do 24 hours but dont think there is ne benefit and u guna just waste electric.

Haha, I was right about to post this question!

I have 4 plants that I do absolutely nothing to but the occasional watering. They sit by the window all day (I live in Florida in a condo on the 15th floor) and it seems to be just fine for them...

...but I also have 1 plant I've decided to have control over. It just broke through the soil yesterday morning, and since then it's been underneath a 32w circular CFL every hour of its life (of course, I took off the plastic shroud so there's nothing between the light and the plant):

So far, so good...in the 36 hours that it's been alive, it's already about an inch high, and it's already grown its first set of leaves apart from the cotyledon leaves.

del66666, why is it that only 16.5 hours of light is "usable"? Does the plant need to "rest" after a long day of photosynthesis?

 

[del66666]

got a friend who does horticulture who says after 16.5 hours the light does nothing, other chem processes take place, i guess every living thing needs time to sit and rest,mayb thats just me.

 

[Scranny420]

I don't mind keeping a 32w cfl on 24/7 for a while...it barely uses any electricity anyway...

 

[emptypool1]

yeah i grew with mine on 24 hours
my plants LOVED IT
but when they got to be 3 weeks i took them to a 20/4
and they really love it.

 

[del66666]

global warming te he he

 

[Scranny420]

Oh don't give me that global warming crap...the amount of methane produced by 1 cow during its lifetime will affect the world's temperature more than my measley closet grow.

 

[del66666]

i dont drink milk or eat meat so dont blame the cow on me.
