150w HPS Club: Inspirational Resource

Okay so I've got a quick question.

I'm using a 150watt sun system 4 without the glass screen. Sometimes my temps have been getting a little high, around 87. The plants haven't been affected by the heat but I would like to get all of the new kinks worked out before I start flower. I have 3 plants that were started from some pretty tasty BC bag seeds. They are 15 days old and really starting to branch out. Just started LST today so I hope to see some good results.

Would it make any difference in the temperatures if I bought the glass screen for the sun system, and if so how much??
I want to make sure this 1st grow goes well in the new box before I start my white widow and blue mystic from nirvana.
Thank you and +rep for any knowledge sent my way.:bigjoint:

the glass screen will protect your babies yes.. but what you really need to add is a cooltube. there are plenty of Do it yourself forums on here.. or buy a fancy one.. It helps with heat alot.. any pics of your LST work ?


heres mine i built for my 150hps


cheers

I would isolate the ballast and as chronicdice88 mentioned, run a cool tube. Search the DIY section for ideas. I use a hurricane lamp that is a 4~5/8 flare on the end connected to 4inch dryer vent. One end of the cool tube is open to help with the flow of fresh air, the other end has a 134CFM PC fan pulling hot air out.
I had the same SS 150 and heat was always an issue until we modded it.

peace.

Hmm, i like the green led fan light idea... thats nifty.

But damn bro, you need your self a better cooltube, just sayin, with that thing you probably get 2 cfms, maybe 2.8 but i doubt it.

Yeah I have the same model, run some piping (the kind for your dryer) over the three vent slices on the side opposite the ballast. Put the other end somewhere outside of the room with a small fan sucking the air out of the side, works for me and have constant temps of around 79 deg.

Alright sounds good. Thank you for the replies. I'm ordering the glass tonight and I'll pick up the other supplies when my next pay check comes in. I know a guy that works on motorcycles and has a plasma cutter so I'll see if he can cut a nice hole in the reflector for me.

Here's a current pic of day 16. I think they are growing at a pretty good rate. The yellowing on the far left was my bad. Took a trip to FSU for a few days and they dried out a little.

its all about the bang for the buck. whole cool-tube/light setup was under $50 im very happy with the results.

more $$ for chronic ;)

Hey everyone. I am new to growing and need to know about how many plants can a 150w hps system grow and will it be efficient enough for the veg stage of the plant of will i need another light seeing that hps is supposed to be the best for the flowering cycle.

Thanks in advance

If clones you can get away with more plants, with a large plant I would say 1 to 2 for great coverage, all depends on how bushy the plant is, mine is really bushy so need to get the coverage. Or you can lift the light a little higher and supplement with some cfls on the side, also depends on the light I think and reflector type. I use the all in one sun systems so the coverage is a little less.

Plants per lumen is entirely dependent upon grow type. Grow type is determined most often by space available. Grow space often limits you to certain plant genetics or will at least determine the technique used to grow specific plants.

150's, 250's and most CFL's are great for SOG, SCROG or LST techniques to get the most of every square foot based on a minimum number of lumens.

Yes. A HPS is very sufficient for vegging.

What is your grow environment like and desired yield? What are you growing?

Do you have a separate clone area/chamber?

I am no expert but these are the issues I have encountered while starting a mini 150 HPS stealth grow.

More details about your predicament make your answers more obvious to those who have been there already.

Dingbang, the space is 3ft in length by 2ft in with by 5'2'' in height. My desired yield is at least 3 ounces. I just have a pill bottle full of seeds. Unknown strains. I just saved seeds over a few months from different batches. No separate grow area/chamber. I just planned on getting a black 5 gallon pot and cut a 3 holes in the top. 2 for the 3-5'' net cups and 1 for checking water ph and for my air pump and air stone to ease into the bucket while using something to cover the little hole. I was also wondering on average how long would it take for the veg and flowering stages. Thanks for the help it is highly appreciated.

Hey it sounds like your best way to go is SCROG, you can call and ounce per foot "par" with this method

would a 150watt hps work well in a 14"deep 19"wide 21.5"tall box? this is the max size i want to use and ive always wanted to use a 150watt hps but now im wondering if itll heat up to much. i was planning on running 2 120mm exhaust fans.

this case will strictly be for flowering on a 12/12 schedule and i will be training the plants

Hi everyone. I am a newbie and i just wanted to know if anyone have any pics of their harvest using 150w hps light, who think they had the biggest yield with it (how many plants), who has had the biggest yield in ounces from the 150 with 1 plant and the strain they used. Thanks. Really considering a 150w hps light.
Any help would be beneficial.
