Check out my post #1713 a few pages back. i have a list of parts that i bought from lowes with upc and package codes. as far as the contactor you need to get that at a heating and cooling shop, lowes do not carry them anymore or at least thats what i was told when i inquired about them.

Ok got another question. I picked up the blue labs truncheon ppm stick but dont know how to actually read it. There are 2 differect scales for ppm. one is 700x ec the other is 500xec. since there is a differecne of about 400ppm between the two which one do i use?

Thanks for the reply SB. I would like to apologize for my ignorance in advance but can you tell me why you would choose the 1 600w over the 4 150w's? is it because they dont penetrate as deeply or is 150 watts only 150w meaning i dont add up the 4x150w=600w? I was thinking of the 4 150 because...

Ok i have some question on lighting, seems i fell asleep during that part of class. Say i have a small grow space that i would be able to fit 3 single posts systems. I dont have any lights yet so i'm a fresh slate but on a very limited budget for now. So my question is how do you calculate...

Are you using any type of medium or the net pots with neoprene collars? I would place the seeds in a folded up paper towel and then slip them into a ziploc baggie. Then lay them flat somewhere cool and dark. Check them in about 3 to 4 days. If you are using the net pots and neoprene collars you...

Hope Andy dont mind but i can answer this for you Simply put the answer would be no you do not need this if you are running a 30amp timer. also you do not need this if you are running only 2 pumps then you are good with 15amp timer. These 396 pumps are like 4.4amps running and jump to...

What you state is true but because there is an open source of flame and oxygen is in fact an eccelerator and fire needs oxygen to continue consuming it would be a bad idea to have free flowing oxygen in the same room as an open flame. To me this is just standard safety just incase that furnace...

in your post you state you are "Burning O2" I am going to assume you meant CO2. If this is the case then no you will not blow yourself up since CO2 in non flammable however with that said you also state you have a wall furnace in the same room which needs oxygen to burn cleanly. If this is in...

here you go. If i were you this would be ideal since its only 10ft away. This setup will cost you less the $50 and a cheap timer will work perfectly to run your light. Instead of the dryer plug i would buy 12 to 14 ft of 8 to 10 gauge wire with a dryer type of plug to make it long enough to...

Andy, Just an FYI now that i am not medicating. in your schematic i noticed that you made an error that i just now caught. the fuse you inserted going to the timer may be to high unless you have a different type timer then most of us are using. The timer such as what SB uses has a max output...

Its not good because the start up amperage is higher then the running amperage. So if your timer is rated at 15amps and just for this example lets say each pump runs at 4 amps and you have 3. So you think you are good since 4x3=12amps right? Wrong! For a very brief second at startup lets say it...

unless i'm wrong your would need a 24v transformer to make that work. Its can be done but the transformer cost about $30 or so.

For those wanting to build the "Andy" Timer control here is what i did and it cost less the $30 but i already had a timer so the $30 was just for the other supplies i needed. Work perfectly by the way Thanks Andy for your how too. Went to lowes and bought 1. a pack of 2 power strips since...

I have a question for Andy With the drawing you have and the contactor you are using, and i may be wrong here, but couldn't you tie the neutrals(White) wires together on the load side and just connect the hot(Black) wires to the contactor? Meaning in the picture of the contactor you have you...

Hey Gringo Thanks for the reply. I hear what you are saying about the different variables and such as i have read the entire thread along with a bunch of others but there has got to be somebody out there that can give me an educated guess vs just a guess and i would be more then happy because...

Ok i'm gonna try asking this question again because it wasn't answered so please bear with me. Mr Stink or any others here doing SB's system. have anyone tried doing an every other harvest or every other plant a single top cola for the purpose of allowing some plants to grow big and well the...

Not saying your wrong but wouldn't pulling the air through a water filter cool the air also? I see where you are going in that the air would not be obstructed and x amount of tubing needs to be used to cool x amount of heat in this manner. I mean it does cool the hit coming off a bong with a...

GreenDaze thank you for your reply.

Actually i dont have a need for this as i do not grow but am doing research and had a brain fart with this idea popping into my head, just thought i would put it out there to see if it made any sense. Also i know that the smoke from a bong still smells but i was just putting it out there as i...

Dirthawaker if i am remembering correctly you were the one with the humidity problem right now and dont have the funds for a dehumidifier at the moment? If so have you tried to use that product called RidEx or something like that. Its these very water absorbant crystals that supposedly suck...
