well i guess i should start off by telling u what i have first so u will know whats what and not have to ask to many?.i have a 7x7x71/2 ft rmwith half for the grow space. a space for the seedling dome, and i have my 3 ballast boxs up on a shelf to the left 5ft up. and my light in the middle to back of the room. and an ac unit on the right side about 4 ft up right in front of the light. so as it can blow through the hood's 4 inch duct. and i have it set up on a carbon filter/same duct meaning i can hook up that sides duct with the carbon filter or take it off and let the a/c run through to the other side. where the duct from the inline fan is to suck the air out of the rm. i have a dwc system i made but not in the buckets. i have 4 30 gal rubbermaid tubs that holds 8 plants each. with a pvc set up with 14 sprayers each i got the 360*ones. as i have bought others and the 360*ones just out do the others by alot. it sprays all over and the back side of the spray hitting the walls and bouncing off. and with the bigger openings it looks like they might be harder to clog up on me.


anyways my lighting system, i was online looking for the ballest lite hood and everything. and found this guy on cl an online trade site. and a guy had a 400wmh set up. (ballest lite 2 bulbs lite hood with 4inch duct and a box of air stones about 5 with 5 air pumps 3 inline fans for the ducting then 2 set ups of the 1000w mh and one a 1000w hps/mh set up with a ballest box and hood each and a bunch of other stuff) like a tds tri meter ph ppm temp. and other stuff he was wanting 2300 for all that was a good deal in it's self. so i went to meet him at his storage cause he was moving up north. and had it in storage i had to travel a good ways out of town to meet him. but he had me waiting for awhile. so when he got there he was way behind. so i told him i would help him pack his stuff up if he would give me a better deal. so i did i did most of the work i might ad. at the end he just gave me all the stuff for free well i helped him move but no money. so thats why i have all this stuff. and was trying to put it to good use. all the stuff for the lites are from diamond anyone know of that type of lite?? they seem good to me i like um.


so what i did cause of the limited space i have.i took all the lite out of there hoods.and i picked the biggest one.it was the one with the hps setup.and it had room for all three.and for sum odd reason it already had the hole cut out and set up for 3 lites.so i mounted the other to mh (1000w and 400w)on the sides of the hps.now im not gonna run all at once but 2 at a time won't hurt like the 1400w of mh or 1000 mh 1000 hps or what ever so thats my set up pretty much now my ? is and im sure i'll have others. but 1st one is how can i change the humidity? it's been staying around 65 to 80% with most of the time around the 70 mark. is there a way to dry it up a bit. i know how to make it higher that part i know. but how do u lower it is there an easy way. and the reason it's been so high is because it's been raining for a few days. will that hurt at all or is it ok to be humid for a few days. and i keep the room spotless it's clean. any input would be great!! oh and 1 more ? what is ur thoughts on well water/hard water well im sure it's hard i put my meter in just the water and it's around 23ppm (230ppm) is that considered (hard)oh and the ph on that water is around 7.8 to 8.1 and sumtimes lower

Don't worry, if there is a problem a mod might move it into 'basic' or 'indoor'.

Humidity can be a bitch. I see you emphasize cleanliness, and that is a VERY important goal when you go through periods of high %RH.

An air conditioner is almost indispensable in most indoor situations. Not only does it control high temps, which can be a KILLER, but it strips excess moisture from the air.

If you don't need the cooling, a dehumidifier is the next choice. Remember to keep it emptied so it keeps running.

Your water may be a problem, not as much because of the ppms, but because the pH is high. You will have to make up your fert mix and then adjust to pH in the high 5s low 6s because I see you are going to be running an aero grow.

Bonus on the dehumidifier, it is sometimes possible to use that for a source of water distilled water. Check the ppms in the catch bucket! And don't forget to use your calmag plus!

There's lots of good help in the hydro section. Good luck!

thank u for the help another ? is how do i know when it's time to move the seedlings to the aero i have 5 lil plants growing i planted on the 14th and there about an inch now. the stems coming up is red on one side and a nice green on the other running up the stem the leafs are tough looking thick but when i touch the plant it seems loose in the rocwhol maybe the roots are'nt deep enough? and iv'e noticed 1 seed has not sprouted at all so i opened up the hole to look in it and there was white fuzz stuff on it and it was not sprouting at all.everything else seems fine other thani don't know what i can do about the water down in the tub im starting to feel a thin layer of slick stuff im guess it's alge and all the tubs i painted black and the tops black then white so im guess the light is getting through the clay balls around the edges so maybe sum plastic over top of them?
