after some investigation I found that my Digital greenhouse 400w digi ballast was shutting down because the base of the hps bulb had insufficient contact and had melted the lead. I suppose that it was a good thing that it shut off when it did. I replaced the bulb with a homedepot metal halide...

hey moon how did that set up work for you. I had the same idea to cool my rez of 10 gallons. I might try putting a 2 inch vacuum hose coming up from the lid of my rez and connect that to the suction side of my lite cooling fan to see if the airflow will cool it down a bit as well. My...

I bought a digital ballast from HTG (Digital Greenhouse brand) It worked great for a month and then went tits up it will fire the lamp for about an hour and then shut down. I am going to upgrade to a Lumatek and keep the replacement HTG (haven't sent the old one in yet) as a backup. I would...

why in the world would you go to all that trouble to save a few dollars and end up with something probably rigged together and only 250 w. All the time and effort and money and if it doesn't work perfectly youll spend far more on it then going on ebay and getting a new light with ballast and...

i added some cfls as a backup so the light cycle wont get to messed up and the temp was measured a about 6 inches above the light so i imagine it registers abit higher than the grow itself. I would move the gauge and measure the temp at the canopy itslelf but oooh i guess i cant my light...

I have a Digital Greenhouse brand 400w HPS digital ballast with air cooled hood. Its worked great for about a month on 12/12, but now shuts down randomly. The ballast is even cooled, I built a duct around it to flow the exhaust air over it. The top of the hood maintains a pretty steady 90...

hey check out grainger.com for shaded pole blowers. The clearance ones can be cheap for a good blower.

the fan wasn't wired to anything but the power cord with the hot wire on the low speed terminal, the polarity was correct also. I suspect that my air intake wasn't large enough. At least there is a warranty. A

So I have a 3x5x5 grow area with a 400 W HPS with an air cooled hood and a 4x12 charcoal carbon scrubber with a TD 100x that is 135 CFM with out the scrubber. Anyway I had ordered a TD 150 to cool the light seperated from the grow to keep out most of the heat so I can add CO2 and the god...

pot plants are like people. Most would rather die than go through a sex change. So just kill it and put it out of its misery. Unless your into that kind of thing then you can just dope your nute water with some estrogen. :rolleyes:

I was on a MMJ forum at MT NORML as a friend of mine is getting a mmj card hopefully soon. I'm not sure what her doc. has said yet but I wouldn't believe it if they denied her. The MAYO clinic recommended it to her a few years ago, but she hadn't tried it until recently. It helps her deal...

the larvae where probably in the soil u used. even stuff from the store can have parasites in it just waiting to get your babies.

if i were you I would get a "little red wagon" to haul dirt out and supplies in. Could make things easier you could have a rope on the handle to pull it. Also as stealth as this area is I would go all out and make it worth the trouble of putting a settup together. Automation will also be a must.

Id cut it off at the weak point. that way the plant puts its energy into the healthy growth. Think of it as if you just pruned the plant.

I ordered my 400w remote digital ballast system from HTG supply. Totally happy with it. I don't see why so many people go with cfls. THe HID is soooo much better and really not that expensive. It looks to me like that system you are looking at would be alright. Id have to look at the...

I can't even remeber what the book was called but in it the people made a setup where water was piped in through pvc pipes, and out through sprinkler heads into 2 liter bottles that where upside down, with the bottom cut out and turned inside out for a cup to hold the plant. The idea being that...
