If you want good PH'd water. Use rain water. It's PH neutral at 7.0

It will not hurt to use tap water. You just need to be aware of the PPM of the water before you add your nutes. As far as the ph goes, get some PH up and PH down to get it where you want it. BTW. Who said you didn't have to worry about PPM in soil?

Hello all. As winter approaches. I am concerned with my incoming air temps. I have a 7X11x7 insulated grow room that has been constructed inside of a non heated/cooled area. This area gets very hot in the summer and very cold in the winter. The grow room is insulated very well and I am able to...

Hello all, I am in the process of building a new grow room. I currently have a 1000w HID sunleaves light. I am wanting to grow 8 plants on a two week rotation so I can harvest every two weeks. I will use the SOG method for this. I have been thinking of dropping the HID light and switching over...

Cool, thanks for the help.

Ok will do as soon as I get home. Will they fall off after dead or will I have to pluck them to keep from smoking dried dead mites. Thanks

Hello all. I am about 2 days away from harvest and while inspecting the buds with a microscope I noticed the small red spider mite. You cant see them without the microscope. I have only found a couple and try to pluck them off. What should I do with only a couple of days left? Should I just...

Hello all. I am about 2 days away from harvest and while inspecting the buds with a microscope I noticed the small spider mite. I have only found a couple and try to pluck them off. What should I do with only a couple of days left? Should I just discard the buds with the mites and keep the rest...

I've been adding water to get the PPM ratio that the feed schedule recommends, but why would it be listed as that when you cannot achieve it with the amounts on the schedule? Thanks

Hello all, I have a quick question concerning the PPM of my nutes. I am using General Hydrponics Flora Grow, Flora Micro, and Flora Bloom. I check my water for PH and PPM before I mix my nutes and my PPM never even shows on my EC meter. After I mix my nutes according to the chart my PPM should...

Sure you can go this route. You have to survey what your needs are. A 3 ton A/C would be a massive waste in a non-insulated tent. If you want a serious grow, I would build an insulated room and then you could be efficient. If you are going to grow for commercial purposes, then add the lights and...

In reality what you have to worry about is that your wire size is correctly sized with your overload protection. NEC section 310.16 will give you the amperage that any type of wiring can handle. If you want to use a 20-30 Amp breaker, just make sure that you are using at least #12 THHN (and I...

8-10 1000 watt lights would be a major overkill and would be almost impossible to keep the inside of the tent cool. Are you putting this in an air conditioned area (basement,house)? That would be the only way to cool this thing is to vent hot air out and cool air in. 10 X 20 is only 200 square...

Ok let's look at a 1000w ballast on 240v system. To find the amperage, we say 1000/240=4.2amps. With two of these it would equal 8.4 amps total. You don't want this on a 30-40 amp breaker. If something happens within one of the ballast, it could catch on fire before the breaker trips. What I...

Hello all. I am using supernatural grow aqua in a DWC system. My PPM is running what I believe to be very high (1800). What can I do to control this? Less nuts? My PH is consistent around 5.8. Any help would be greatly appreciated.
