grow "closet"

i have a 2'x1.5'x4' grow room and have a 2' ecolux fluorescent plant light 750 lumen, 20 watt is that good enough for 1 auto strain plant????
thx.

A t-12 set up is cheap and works.

I have this set up I use from time to time.



They can grow into it for a few hours to a day they stay cool.

My set up is (4) 24" T-12's 20 watts each at 6500k it's a light blanket.

I also have some 2600ish k's (don't use but may add to my hps room for some side lights).
These thing may be old school but you can not f--- it up.

Not really, no. I've typed this out a few times already today so I'll give you a link, save the wear on my keyboard... https://www.rollitup.org/view.php?pg=faq&cmd=article&id=259

my lights are F20. any good for my situation? by the way im totally new at this stuff.

Sorry, that doesn't mean anything to me. I'm not a fan of fluoros myself, but I can see why people use them. You will need more than one, and I'm pretty sure cfls are better on a lumens per watt basis, as well as being more space efficient than tubes.
Get 10,000 lumens in there at an absolute minimum, 20,000 would be better, more if you can fit them in.
You'll only get out what you put in, you gotta give a little to gain a little.

they work but are in the range for when you switch to 12/12 for flower.

for veg the daylight 6500k works best.

that one on the bottom is one of those f20's

Check the link in my first post, here's a few more https://www.rollitup.org/view.php?pg=faq&cmd=article&id=57

There's so much to know that I wouldn't be able to give a small tutorial for fear of missing something important, but if you've any questions after reading those just pm me.

the one i have is green the cove of the light not the actual light itself. but its 24" ecolux plant and aquarium F20 750 lumens, 20 watts, cri 90 (what is the cri?), and the label reads it promotes red radiation
thx. good smokin + rep

there is a set of these at home depot.

yellow cover
blue cover
violet cover
red cover
green cover.

they work just get the correct color temp. I is on the side.

6500k for veg
2600k for flower

or as close to the # as you can find.

back in the day all indoor grow just used 5000k all the way thru. or 2600k

mixing them also is good.

CRI stands for colour rendition index. It's a measure of the quality of the light from a light source in comparison to sunlight (with a maximum value of 100). The closer a light source's CRI is to 100, the better it's ability to show true colours.
It's more or less irrelevant to growing, since we're only interested in certain parts of the spectrum (red during flower, blue for veg and maybe some uv to increase resin production) rather than trying to reproduce the colour spectrum as a whole.

so what light should i get for an auto flowering plant. only 1 or 2 for veg and flower stage?

for auto flower do a mix of 75% (3) what you have and 25% (1) of 6500k

or just use what you have.

Even an autoflower will have a veg period, albeit a short one. It could be days or weeks, depending on the strain. Before it starts flowering it'll respond better to 6500k, but using a mixture is perfectly acceptable. Just make sure whatever light you put in there, that there's plenty of it.
