Cabinet grow and 400w hps

is a 400w hps too much for a cabinet grow
should i do a 250 or something like that?

i have 2 closets the double closet has the 400 and the single closet has a 250, but if well venterlated,will also take 400. it all about controling the heat. if you have a single closet a 250 hps should be ok for 3 to 4 plants. 6 plants for the double closet with 400 hps. how big is the closet?. any pics.

no picks yet but it is about 2 1/2' across x 2' deep

What about the height? If you don't have enough room to move the lights high enough, the light could burn your tops.

I have a 1000w in a pretty small space but have a lot of ventilation.

im good on hight bout 6' 7"
but it will be a veg room only

I would go with the 400 but i like a lot of light.

my cab is 26 deep x 36 wide x 40 high.....supposed to be designed to handle 9 plants.....I only have three in there now and its almost too much....though I have made no efforts to trim and keep tight structure, one 400W superHPS.....works like she's built! excellent results so far.....at least from my perspective....I aacknowledge many others with considerable time under their belt that would have lots to say to improve.....and over time I will try and leanr more and adapt better

Can i use a 400 HPS through the whole grow cycle--the prob I have is I have a flowering girl on 12/12 and I am growing Agani buds still veging and I am supplimenting them with Full Spectrim Floresances. My question is how much will I loose on the Afgani yield. After two weeks of this regiment they are getting wider but not Taller.

hps is not recommended for vegeing.....better choice seems to be MH or hog-ass-big CFL (I use a single 200W).....

I agree--I have A conversion bulb MH. But the prob is I used bad timimg in overlaping my budding and growing cyle(I am a newby). One bulb makes it hard for me to choose between the HPS for betters yeild on my girls , or veg growth on my new plants. I have Florecent lights supplimenting , but I know this will buy me only a little more time.
I have heard that you can use the HPS and get VEG growth with a little lose in time.

It sounds like you are trying to flower one set of plants under 12/12 and grow another set under 12/12. it doesn't work like that. 12/12 triggers flowering regardless of the size of the plant. If you started your Afgani under 12/12 you are going to lose most (if not all) of your yield.

whered you get a 200w florecnt from and how much did you spend on it?

they are reasonably common now.... Fluorescent Grow Lights ..... I didn't pay this much for mine....but it certainly is a beast!

if i have a card board box with light reflective sheeting inside with 3 100 watts bulb and well ventelated will this grow my plants

yes, you might also consider some air movement like a fan to keep the air moving and fresh.

I tried to veg with HPS for about a week or two. NOT RECOMMEDED! My plants started acting funny, leaves twisting, un-even growth, and purpling of stems. Once I put my MH back in, it started to look normal. If you have the proper vent, go for the 400MH for Veg. My 250MH ran ALOT cooler than 400HPS.
