You can use Hydrogen Peroxide to Aerate your res, and of course aeration is very necessary for your plants. It can also kill bad (and good bacteria). I would limit it to maybe one third of a cup in a 30-40 gal reservoir. To determine the health of a plant, you can look at the leaves. If they...

I have a low ceiling restriction, and love the drip system I have right now. Presently I have 2 trays 4ft by 4ft and 10 inches high. The bottom one being the reservoir, the top one is the plant tray. The top one is separated by a couple of 2x4's.... and of course the reservoir catches the...

Nothing wrong with that! excellent!

I should also mention that the ballasts ideally should not be in the grow room adding to the heat. But even then, there is a lot of heat generated by the bulbs, and if its a vented 1000W light, you could probably fry an egg on top of the lamp.

That sounds excellent. But that 68F, could be misleading. For example if its summer time and the outside (cold) air being drawn in is 80F, there's no hope of getting the temp DOWN without A/C. Then you need to figure out how much heat your lamps put out. Four 1000W lights will put out...

When you are using the cleaned air and re-directing it back thru your lights, that temperature is perhaps 10 or 15 degrees warmer than the temp inside your growroom. So if your growroom is say 75F, your exhaust might be about 90F. So you are running the lights starting with 90F degree air...

Well, I would use the 12" on your scrubber and exhaust it out. The scrubber would be up as high as possible so that the warmer in the air leaves the room first. You might consider hanging it horizontally from the ceiling. I would use one 6" and hook up all four lights in a daisy chain and...

Well, I was in the heating ventilation and air condiitioning biz for about 10 yrs or so.... I really don't believe you need a 6" fan for each 1000w light... I can tell you that I set up a guy with 4 1000w hps and a 600 hps, with a scrubber the size of a 40 gal hot water tank using only one...

Generally speaking, the size of fan you need, will largely depend on what you are trying to do with them. For Example if you have 4 1000W HPS or MH lights in there, your answer would be a lot different if you were a couple of fluorescent tubes there. In other words, you need to specify what...

Well, perhaps too much water, or mold/fungus...but why does it only affect the cuttings with the ones dipped in cloning gel? there are no nutes in the water with the exception of the gel. In my aero cloner, I've been changing the water every other day since I've been having these problems, and...

Looks like I'm gonna have to read up on Hicks.... BUT I potted the first clone with roots from the healthy batch I had left which was straight tap water. It took 9 days. I do believe that's maybe 3 or 4 days longer than my aero cloner. HERE'S MY QUESTION: What is it that seems to eat away the...

I've been having problems getting clones to root lately. I use both botanical aero cloner and rockwool cubes, and have found the stems start getting slimy after 2-3 days and most eventually never make it as a clone. I've tried everything I could think of including completely disinfecting my...

I"m running both ebb and flow and drip using hydroton on a 4ft by 4ft tray. The ebb and flow I run every 4 hrs for 15 minutes. The drip, using filter and just 1/4" lines, are run continuously for the first couple of weeks, and then one hr off one hour on. I've found in the beginning of the...

it depends soley on how big your plants are at the time you want to start flowering. I use a 4x4 tray in ebb and Flow and use 15 with a 1000w

anything that will cover them up..... even if you put plastic sheeting covering the whole tray with holes cut just so your plants get thru, but no light on the roots.

You should cut off any part of the plant that got burnt or damaged. Otherwise the plant will want to "repair" those areas, where you want growth and size. once your plant is getting as far into the light, you should tie it down so that the plant will not grow into the light as before. It is...
