250w HPS Club And Help Guide

pretty interesting grows you guys have! im thinking about getting a 250 for my 2.5x2.5 area with maybe 2 added 70w hps' alongside the 250. currently using the 2 70w's on my white widow so i might as well use them with a 250...good idea? or not?

if you can control your heat i would say go for it!!! i would get a 250w and see how the heat is with all of them on before you start growing but more light always help:eyesmoke::eyesmoke:
 
This is a old post thought id re-post it:o..

250w.. increase your yields

I find that most expierenced 250w users seem to lean towards LST, SCROG and SOG to increase there yield..

With a 250w you should be keeping your plants short for better light penetration. By using the methods mentioned above you should see a increase your yield.

250w penetration is not very intense anything below 12" of the light is not worth a bud site. This is where LST and SCROG come in with that in mind you should be leaning towards a even canopy of buds so that light penetration is equal.

250w puts off less heat with proper ventilation you should be putting your plants at 5-7 inches from the tops of your plants.another plus is with less heat you can run a 250w in smaller space such as grow cab..

If your not already a Hydroponic setup will also aid in increasing your yield..

SOG.. from all the different sog's i have seen the most plants for a 250 would be around 12 plants... 4-9 plants would be ideal...

All this with good nutes, balanced ph and perfect temps you should be yielding the max with your light!

please feel free to correct me or add anything i left out!!!:eyesmoke::eyesmoke:
 
ill try to get better at growing then i'll give scrog a shot, seems well worth it. so pretty much if u do a sativa dominant plant the lower buds arent gonna be as dense? the 70's dont put off much heat i had one right on top of my white widow but with no ventilation on the light or the top of the plant and after 2 weeks like that it just recently started getting a little burnt, it was about an 1" or 2 away from the top of the cola so maybe i can use the 70's enclosed with ventilation as side lighting maybe...
 
Just got done building a small room for my 250W I have a MH and HPS bulb. I am building ventilation into my hood and running one main fan prolly 80CFM will be running it to check temps. I am running this with a hydroponic system...most likely shooting for some white strains widow and G13 along with some others...
 
Hello 250 watt club! I use the HTG Supply 250 watt HPS system in a Euro Reflector. My last grow I used the HPS bulb but I fried it because (90% sure) of a hot start on my ballast. So this grow I am using an AgroMax high output MH conversion bulb. I cool the hood with a 6 inch duct booster fan from homedepot that cost me $28. I also have three computer fans for intake and a 6 inch desk fan to blow across the tops of the plant. My grow box is 3' 5" tall, 2' wide, and 1' 2.5" deep. I am growing (under 12/12 lighting) one large female plant and a seedling whose sex is unknown. The temps are 76-82 degrees fahrenheit during the day and 70-65 during the night. The humidity stays around 20-30% almost all the time. Here's two pics of how I'm using my 250 watt. If you wanna see more pics just go to my journal by clicking on the link in my signature. I hope you all enjoy!

Interesting setup Tom your room size sounds to be about exactly the specs of mine to the measurement. Also looks like you picked up the HTG 250W kit which I did as well. Right now I am working on getting my ventilation setup I have already built an aeroponic kit for this closet grow, I have been having a lot of fun putting this room together. I will be keeping tabs on your grows as it offers me a bit of insight...
 
That's fine with me man, if you got any questions you can post in my journal or shoot me a pm. The only difference seems to be that I am growing in soil. I have a DWC unit set up so once I determine the sex of my new seedlings I will cut a clone off a female and give DWC a try.

Yeah that is about the only diff besides some substitutions in contruction equipment (I built my grow room out of PVC and then wrapped in panda film. I have a good amount of time on my hands and this is a personal project so I chose to try the advanced route the first time around. I am a pretty smart guy so I am hoping for the best. Going for that short but robust grow...

i actually thought about running some 70w on the side 's i think that would be great just as long as your circulation is well.. but with just a 250 those lower buds will be airy

right on!! is your ballast switchable?
 
well i actually had a new idea and thought about getting 4' warm fluros to stand up vertical on the sides. 4 plants 4 fluros like that there's light going all the way up and down. and for veg prob the same thing but with 6500k fluros. stores around here want 200+ for a hydrofarm 250w with the hood but without the bulb but that's too much! im gonna go with the htg one
 
hey if you guys are in the usa there is a good site to find used lights go to
www.craigslist.com and seach HPS and youll find some good deals most of the time

i got my 250w floralux with a agro max bulb and a 250w metal halide shop light for $50 down the street from my house its worth a shot
 
ive looked it up on craigslist and have only found 400 and 1000 watters but most of it is advertising from hydro stores so i guess another city would be a good try
 
that sucks get what you can!! ive seen this 250w HPS on ebay for like $100 with shipping or something like that didnt look to bad keep on looking man.. best of luck
