Good to see you have come over from the dark side ;)

I didnt give you the full picture here. You need to start with the nozzle pressure you want to run at. Those tefins should make ok to good droplet sizes at anywhere from about 80 PSI to 100 PSI. Higher is better because the droplets will be smaller. But - you need to have a good spread between...

I need to ask what your goals are with this system. My opinion on HPA and AA systems is that you are wasting your money unless you do it in a way that will get you fuzzy roots. If you dont do it correctly, you will end up with smooth roots - which you can get far cheaper and easier with LPA. So...

Yes, but thats not an ideal situation. If you keep it to 100, it should be fine - BUT - if the pressure switch fails, and the pressure goes to 120, that could be very dangerous. Those tanks explode very violently. Thats why the tank max pressure should be above the pump max pressure. That way...

Carefull - that tank has a max working pressure of 100 PSI. Thats low for an HPA tank, and below the max pressure setting on your pump. That makes it a dangerous choice. The tank I listed above has a max working pressure of 150 PSI. Those pumps are actually designed to run once - for 1 to 2...

Im confused about a couple of things. Is the pressure switch the solenoid that opens to allow water to get to the nozzle? Is the shutoff valve just a manual shut off valve or is this the solenoid? When you say its on and misting - you mean the its misting full time - no on/off with the...

We will have to agree to disagree. Like I said - not interested in getting into a protracted debate.

That power supply says can deliver a max of 2 amps at 24 volts, so you need to add up the total amp draw for each item it is powering. I would recommend you be at least a little conservative and not go the full 2 amps. I personally would limit it to 1.8 amps max. That pump has a peak amp draw...

Sounds good to me.

See, I knew it would get some push back ;) Im not interested in getting into a fight, but here are a few points to consider: 1) Watts from the wall or actually reaching the plant or from the label on the fixture? 2) What about efficiency - LED vrs CMS, HID, etc Big differences here. 3) Distance...

<sigh> I am tempted to let this go, but I will give it one more shot, and then I promise to shut up. Google "how to lower water hardness" and see how many recommendations for using an RO filter you get from municipal water company's, health departments, EPA, or virtually anyone else. They...

Ive always heard in the past that its a lack of calmag that causes purple stems. Also, LED's have been blamed. I dont know if anyone has actually done any real scientific studies, but here are a couple of links from other sites that make sense to me...

LOL that awesome! Sorry, dont mean to make fun of your problem, it just struck me in a funny way - plus Im kind of stoned. Thats not ideal but still pretty cool :) I suspect its a matter of light getting in to the roots. Any light in the root zone is almost always bad. The light will encourage...

You obviously didnt follow the link I posted ;) Try Googling something like "Does RO filtration lower water hardness" and see 1,240,000 some odd links. Everyone from the EPA to every (reputable) RO filter maker on the market, scientific studies, university papers, etc etc. The only way to...

I had the same issue - too much air exchange for the humidifier to keep up. My normal winter time humidity in the tent - when the tent isnt full to the brim - is in the 35% range - I keep the tent around 80F. My DIY humidifier could only raise the humidity to maybe 40% except during lights off...

Wow. Thats an insanely low price for all that. I would want to know what the tech is in the DI filters though. If you are curious about your water hardness, you can get a very very rough idea easily. Just put a small amount in a container with a dark bottom and let it evaporate. if you see...

Couple of questions. Is that PPM the total or the amount over your base water PPM? I would assume your base water PPM would be pretty low with that mix ratio, but do you have a number? What is your tap water like? Is it so bad you have to dilute it that much? How long has it been since you...

A couple of points. RO systems dont change your water hardness. Thats because they dont filter out calcium or magnesium very well at all. Water hardness is just a measure of how much dissolved calcium and magnesium is in the water. So using RO doesnt have much if any effect on whether you need...

Oh - I forgot to mention - those mysterious fungal/mold spots on your leaves were probably due to your humidifier. Visible 'fog' is not actual humidity. Its micro droplets - just like the ones you are spraying inside your root chamber. Its only after they evaporate that there is a change in...

LOL!! Exactly why I do it too. Well that and Im addicted to fuzzy hairs :D P.S. shhhhhhh dont tell anyone or you will get into a fight, but grams/watt is 'stoner science' and completely meaningless ;)
