250w HPS Club And Help Guide

[MostlyCrazy]

15-20k difference but with the 250 I was able to manage the heat with some properly placed fans. With the 400 I wouldn't even try it without a proper ventilation system in place.

 

[tom__420]

Yeah that's true.
When I bought my ventilation for the 250 I went a little over board so that it could be used to cool my upgraded light. Good thing I did

 

[MostlyCrazy]

Yeah, I always over buy just in case! By the book I would only need about 120cfm blower for my area but I went with the 265 and it can suck any heat from my 250 too.

 

[tom__420]

I use a 306 CFM 6 inch active air inline fan. Works great and is pretty cheap too

 

[Wretched420]

Man the 400 watt puts out so much more light than the 250 watt, there is a very noticeable difference in lumens

yea man i been thinking of upgradin or running 2 - 250w i dunno yet

Hey Eveybody!!! Love the thread...

Hey I just ordered my 250 watt digital balast from ebay for my first grow attempt. I have a question about how i should design my hood... I am creating a stealth grow operation and my space is 36in wide 18in deep and 5ft tall. I was wondering which type of hood i should design to hit the plants evenly as it is long and narrow...

I know alot of people are proponents of horizontal lamp placement but will pic1 refelct the light more given the spacial constraints?...

Pic 1 - where the hood will be much taller but hard angles on the ends

Pic 2 - horizontal and much more shallow

Also Anybody have any recomendations on HPS 250 bulbs?


Thanks, CC

My cab is almost the same size and I prefer horizontal bulb placement. For a 250w ballast I use the Super Agro 270w bulb. Higher lumens than a standard 250w and also has the enhanced spectrum with extra blue in it. I prefer a mixed spectrum for flowering over pure red spectrum.

Hey Guys,

Quick question about plant numbers in my new grow box. I have a 2 X 3 X 5 box with a 250 WATT LAMP and several 42 WATT CFLS. I have several unknown Indica strains to try out. I am thinking of SCROG or just LST. How many ladies should I do? I am thinking 3-6? What kind of yield have others gotten with a similar setup? Also.. would a COOLTUBE provide me any benefits? It will be during the winter up north where things get chilly. Thanks for any advice in advance.

Thanks Techno Mage I'm going with your advise on the bulb!

I think your are right on the range of plants. I'd be thinking about 4 or so. I would also want them to be fem seeds or I would plant 6 and figure on getting 3 and hopefullly four. You should be able to lst an indica for the height restriction. The cooltube option is there but up north you may need that heat! LOL! I'd keep it as an option for now. Can you vent the grow space?

 

[infdjedi]

Thanks for the reply + advice. I am going to start from seed and veg + determine sex, pick my favorite, then take a bunch of clones and start again to flower while keeping one or two to veg for new moms. I am debating on venting into the attic or outside, but at the very least I will vent into the room its in. Another question I had is based upon my area restriction. Should I get 3-4 gallon pots and veg them for a while and constantly LST them out to take up the entire 2X3 space, and then at 18 inches start flowering? Or.. use smaller pots and just wait for 2-4 colas per plant and a height of 18 inches, then switch to flower? Either option would give me more than double the space to grow when they flower. Thanks again for the help.

 

[MostlyCrazy]

Not a soil grower. I'm hydro. Can someone else help Infdjedi?

My only input is that I like to raise my babies to adulthood, take clones, switch them to flower and harvest while keeping my clones in another area with a 24/0 light on them. Might not be possible if you only have one area. Think it might depend on how quick you want bud.

 

[The2TimEr]

Thought id stick some updated pics up, getting there slowly but surely cant wait to see these in a few weeks time!
3rd pic is the roadrunner she's starting to straighten back up. The other small plant you see is a California hash plant from dinafem (another freebie)
Could any1 tell me if they think i could grab an oz off each of the auto's ??
Also should i chop any of the lower leaves off that are more dead than alive?
Thanks

 

[MostlyCrazy]

An oz should be no problems per auto plant. Probably a little more. Good number of bud sites and plant helth tells me so.

I remove a leaf when it is mostly yellow. If you pull on it and it shows any reisitance then leave if for another day or two.

Thanks for that mate will be over the moon if i can get over an oz off each of them.
Yeh the oldest leaves at the bottom of a couple of them are dying but still well held on, i'l just wait for them to loosen up i suppose.

well your space is close to what i have i would do what you think would work best for you..seems like you got a good idea.. if i were you i would try the constant LST with the big pots.. you most likely yield more with LST and bigger pots and as far as how tall they are i would try and get and even canopy with the LST and just start flowering.. but this is IMO im truly suggesting it cause i think it will work great and because i have never tried LST with big pots so you may be sitting on a nice fat sack at the end of this... but im high only listen half the shit i say hahah

Not sure how many plants that is really up to you. I would suggest an air cooled hood connected to an inline fan

yea i would suggest the same and as far as how many plants that is really up to you like tom said.. you could Scrog 1 plant or SOG 9 its up to you


anyone had any harvest lately???
