So what seems to be the average yield with the 250s? Is 4 zones too high a hope? Ive got 4 plants under a hortilux super hps just going into flower now. 2 White Widow, 2 Super Skunk. Went in at 12 inches. Plan to prune up the bottom 3rd of branches, which Ive already started. I plan to put 6 in next round. Have some seedlings. Actually I have some purple indicas sexing soon that I will probably try to slap in there next to the other 4.

the pictures were taken yesterday and just look t the stretch the plat has made. is this normal for it and i moved the light up a bit because i was a bit afraid of it burning it from the significant stretch. and just wondering how much you guys think i could get off this?!

So the first picture is from the 15 and the second is from the 19..

well your light can only support so much room 3 - 5 gall pots run 4 plants at most but i would do 1-2 plants and bigg pots. keep that bulb atleast 5-8 inches close and you can pull some nice yields.....im sure people will shine in im just browsing lazy and stoned and saw your post gotta help a out:weed::joint:

Hey guys

i have a 250 W HPS grow going now but have a couple questions as far as stealth. is it the heat, or electricity use that determines stealth?
how much heat does a 400 W HPS put out?
or even a 600 W HPS?

or is it the electricity use?

my area is probably 3' x 4' and i'm using a 250 W HPS - is this the best or should i use a 400 or even a 600W? i'm doing a hydro grow with 1 container for now (1-20 gal tub) with 8 net pots but i'm finding plants get too big for 8 net pots so i'm thinking of using only 6 net pots (3 3/4" net pots).

any suggestions are completely hypothetical!! wink wink

gab - with those spec lights i dont think you have too much to worry about heat wise.... or electricity wise for that matter - maybe if you had 4 x 1000watters you might have a problem - just dont vent to the outside, mine just vents back into my room and i open a window for circualtion and to allow cooler fresh air in. Apparently FLIR cant see through walls and only detects heat build up in a particular room (see barry coopers vid on youtube just type in FLIR) so if you distribute that heat to other rooms of your house as well or run it into an ac unit you should have no problems at all. Hope that helps

Now my question.. someone said earlier how many plants should you do under a 250... my next grow is going to be 5 as i have a very small grow space 0.5mx0.8mx1.7m and there is potential to get 6 under - thoughts?

A 250 can handle a 3x3 area just fine. I have one res with a 250 over it that is 3x4 so I put in a couple of sets of 40 watt 6400k cfl (two to a reflector using a splitter) when I turn to flower. I can get those 40 watt really close to a promising bud to max it out. You can use a 400 to get pretty much the same thing but you'll still want to add some cfl's for side lights to get to that bud under the canopy. A 400 is a lot hotter than a 250. I have one of each now. I wouldn't attempt a grow with a 400 without proper ventilation for the heat.

Power wise is pretty easy to figure. Your power bill list your cost per kilowatt hour. a 250 is 1/4 of that cost per hour and the 400 is 2/5ths of that cost. My rate is 6 cents per kilowatt hour which is low from what I hear. Here's a sample calculation from my grow. I have a 400 and a 250, some cfl's, pumps, etc so I figure I run at max about 1 kw per hour total. 6 cents x 12 hours for 12/12 and so it cost me 72 cents a day or abut $25 per month in electricity to run my room. Stealth wise that is nothing that will alert anyone that you grow.

Number of plants under the light is strictly a function of the mature height and girth of your particular strain. I grow Barney's Farm LSD and it grows to about 35" max (with supercropping) but has strong side branching. Two fem plants will fill a 3x3 space if you supercrop and turn the netpots on their side at some point during the grow. Turning the netpot on their side involves lifting them out of the portholes about an inch, tiping them about 30-45 degrees and taping them in place. Just don't pull them out so the slits in the netpots show and the roots never see any light. I do this about 3 weeks into flower and the underbud get expose to the light and grow to meet it and you increase your yield.

Say waaaaaaaaaaaaaa :confused:
Lol I'm guessing that was a typo
I think you meant it would be around $25.00 per month
And yeah 6 cents per killowatt hour is pretty low, aren't you lucky haha

Good catch Tom! I corrected it! Thanks. Poor GABrownzfan probably had a heart attack if he read that before I corrected!

Yea, 6 cents is pretty low but I live with a woman who never likes whatever temp is in here! I not sure she understands how a thermostat works! LOL! She has a masters degree but it's no help here!

So here we go to all at the 250 club i hope to have finally found the place ive been looking for. Ive primarilly been a cfl grower until my last bluemystic grow it was so good that my ole lady actually jumped on the band wagon and got me some x-mas toys there is just one problem she got me a 400w hps/mh electronic ballast cooltube complete set up now wait thats not the prob great system to have but two things are wrong my grow area is not large enough to support that and #2 they sent her a cool tube the size of pee wee hermans pecker..they sent her the short ass 9" cooltube when she ordered the 16" obviously im not happy because im almost into flowering nl x haze/skunk #1 /blue mystic bubbleicious /papaya so i need my equipment like yesterday.anyway after reading this thread for over two days ive come to realize my grow area wont support that 400 so i spoke with the vender and hes going to send ne the 250w complete cooltube set up with digital electronic ballast so here are my box set up.. im going to run 2x 80 cfm inline fans for the cooltube fresh air intake and hot air exaust one pushing one pulling.i have another 4" 80 cfm inline fan for the sole purpose of box air circulation and fresh air with passive intake my box is 20" d x 32"w x 40" h i need to know what the thread thinks is this ok i hope to have at least 4 females out of the beans i mentioned will i have problems with heating or light coverage? all help is very welcome and most valuable..thanks and happy new year and merry x-mas..Peace pot proserity

yo bro .. you make sure you give your old lady a big kiss or take her out to a nice dinner..thats a great gift and a kind thought..even though it wasn't exactly what you wanted..i would be floored if my wife bought me anything for growing(she doesn't smoke)..but anyway kudos to the old lady(wife,girlfriend,whatever)...Merry X-mas..
