This electrical timer nearly went up in flames with a 1000W HPS on 110V. It occured 6 hours into the 12 hour cycle. Any ideas why? It is rated to 15Amps or 1750 watts and that was the only thing plugged into it. There are 2 lights and 2 timers on 2 seperate circuits so I check the heat of the...

Is it ok to not use the cooling fan on (2) 1000 watt hps in air cooled housing? In the summer it is on the whole time the lights are on to keep room temp around 90 but in winter with the fan off it keeps the room about the same. My only concern is getting the lamps too hot? Are they designed to...

I was just reading House and Garden's website and they instruct you to FLUSH EVERY WEEK whilst using Shooting Powder. Does this mean to flush once at end of week 6 then 7 then 8 before the big 3 day flush at harvest time? Thoughts?

master kush plants after 8 weeks in flower in an ebb and flow tray in rockwool cubes are ready to flush. Is it necessary to use ro water? I just ask because it takes a lot more water to get through that filter and I thought if I could get away with tap water for the flush I would be saving...

I was told to cover my 4x4 ebb and flow tray with plastic to hold in moisture and keep light from hitting the roots. The plants are in 4x4 rockwool sitting on top of coco mat. A friend told me this may cause the roots to not get enough oxygen... any thoughts on this? Would like to keep the...

There are 6 plants measuring about 46" tall in a 4 x 4 foot hydro tray under a 1000 watt HPS that are about 4 weeks into flowering. Now that the buds are developing the weight seems to be pulling the plants down. One in particular keeps falling down. They are in 4 inch rockwool cubes and sitting...

I have a 1000 watt hps that is cooled by an inline 6" fan. The problem is the light is close to the exhaust window so a bunch of light shines onto my yard! How can I block the light without blocking too much air flow? I was thinking of stuffing some black foam into the inside of the window...any...

I got sold on a co2 controller for my grow room that turns on the exhaust fan when the humidity or temperature reaches a desired level and turns off the co2 at the same time. The problem is it is hard to predict how much co2 to pump into my 1000 sq ft room. I ran through a 50lb co2 tank in 2...

I have two opposing windows at 90 degrees from each other in my basement. One window in intake and the other is exhaust both to cool 2 1000watt hps ballasts through 6 inch flexible duct. The problem is I have 2 big bends in the flexible tubing which has ripped the flexible tubing open in the...

I made an idiotic move and put the Magic Green from House and Garden in my nutrient tray rather than applying it by foliar spray. I noticed after adding what I had done. Do I need to change out my whole nutrient rervoir? Will this be bad for the plants? I think I really screwed up here...:-(

This is my first hydro grow. I have decided to do 3 cycles of 3/5/10 weeks in each for my Pot Of Gold plants. First cycle will be in the clone dome (only 2-3 weeks) then move them to the veg hydro ebb and flo for 5 weeks, then to flower room where they will sit for 10 weeks. This way I can have...

I am 8 weeks into my first hydroponic grow and just performed my first round of clones. I took one cutting from each of the 10 plants currently in veg for the next generation. I was first going to keep a mother plant in the veg room under the light with DWC but now I am realizing how easy it is...

Is it possible to use one exhaust fan that sucks air from a carbon scrubber, through 2 HID lights and then push it out the room? The guy at the hydro shop said I need one fan to cool the lights and another fan for exhaust and odor control. Why not two birds with one stone (or fan)?

I am in the process of building my dedicated grow room in the basement bedroom which measures 12' x 12' with 7' ceiling for the flower room and a 3 x 5' closet for veg. I decided to use ebb and flow trays/reservoirs. Now the question is what size of res should I go with. Originally I was...

I am looking into installing a reverse osmosis system under my kitchen sink then running a line into my grow room in the basement. What type of line would I have to feed into the room? I haven't purchased a ro system yet ... any suggestions? As far as my hydro setup I am leaning towards the ebb...

I am designing my flower room and re doing the electrical. I will have 2 seperate outlets on different 20 amp circuits. Can I put 2 1000watt HPS lights on one of these circuits (4 lights total on 2 circuits). Anyone running 2 1000W lights on the same house 120volt circuit? And it has 14 gauge...

Maybe someone could suggest a some good strains for me and my goals. I will be growing in my basement under 2 1K HPS for flowering with ebb and flow hydro. I am going to be selling this to the dispenseries for profit. I want the most amount of bud possible in the shortest time that the...

I was considering installing a reverse osmosis system for my hydroponics setup as well as my homebrew makings. Does anyone use a at home setup? It seems like it would take forever to fill up a 30 gallon reservoir considering most home units only hold like 4 gallons. What is the best option for...

anybody use this do-it-yourself kit? suggested? http://www.aquahub.com/store/product39.html

I am new to hydroponics and was wondering how far my tray should fill when the pump is on when I am using 4" rockwool in the vegetative stage. These are my first girls in my new setup and just ran the pump for the first time and it only filled up to about 1/2 way up the rockwool, or about 2...
