This was the last harvest of mine. 4 week veg, plants grew waaaaay too fast and my basement has low ceilings, so the plants reached the lights . I veg for 20 hours a day, but the last week of veg I will change to flower bulbs and 16 hour days to let them know flower time is coming. You wouldn't...

I have a 235 gallon system with a 70lpm pump . It's really more about aeration design than the pumps and stones. Get some pvc and attach a 90 elbow on one end. On the other cut an inch long cut out that goes halfway around the pipe. This is for the water inlet. Put a 3/8 inch air stone in the...

Cheap air stones get me just as far as the $40 ones. Just keep them clean. And the waterfall is so efficient. But make a water farm in your Rez with airlifts, you won't need anything but .25 cent air stones from Walmart. Your DO will be off the charts.

Moab 1/8th strength? A little goes a long way.

If you don't have adequate oxygen or temps root rot sets in lowering pH. However.... Most of the time if you don't have nasty root rot pH dropping means they are drinking more water than nutrients, leaving the remaining water more acidic. When my ph drops it usually returns to normal in a few...

Stikk is right... but in a 4 by 8 you should have two lights. You can get away with the res being the same size as the other sites, but a few gallons larger won't hurt.

My totes did the same thing, and the screw and nut didn't really work for me because the tub would still flex and the uniseals would leak. So, I took two cuts of PVC the length of the bin, put on on each side, then tied them together with some 550 cord.

Inaccessibility.

I have a custom 6 site DWC and main res that has a large pump supplying water to custom waterfall fittings within each of the other totes. The waterfall fitting piece itself is made up of a lot of 5/32" holes. Anyways, my main pump quit working on me and didn't realize it, and at the same time I...

I have used CO2 oil many times in the past, and when I dabbed it the oil would vaporize immediately and not sizzle. This stuff I just got sizzles like butane, and when held over a flame the oil lightly sparks up like a sparkler. In my experience water in the oil has more of a popping sound than...

Attached is a picture of the layout in my flower room. It is a 10' by 14' room with 6x1000w raptors, one window in the middle of the room and a large walk in closet. I would like to run CO2, but I know I would not be able to maintain proper temperatures. With the doors closed my room can get up...

Smaller tubes have more chance of clogging from roots, slime or nute build up. If water cant recirculate a tote or bucket will overflow which can cause water damage or burn out your pump rather quickly. The only downfall imo with bigger pipes is they are a little harder to work with. But that...

Give them as much as they can take. Once you see nute burn scale it back.

1. Yeah just put them in the controlling reservoir. It shouldn't take too long to equalize in the other buckets. 2. Your water pump needs to be under what your return pipes/tubing is rated at. For 3" pipe you can have something like 2500gal pump if I remember right. If you are pumping too much...

Nah technically not root aphids. At the end of summer some gnats from out back got in my grow room. I had a hole in that lid for a couple days as I was trying to put a clone in it. I didn't put duct tape over it like I should have and a few flew down in there :(. But the problem is resolved as...

Day 27 update! (since pistils shown).

If I remember right resinator is just a blend of phosphates potash and acids. It's a great product because its an all in one where other lines make you buy two bottles for the same result/recipe. But i just dont think its as special as they claim especially for the price. I didn't mean that...

They are so over priced. Everything they make can be found in other nutrients for $10 less. Do they work? Yep. But other nutes do too for cheaper.

I used to have this problem as well and then I realized less is more. When you start adding all these additives from different companies you can really mess with npk ratios and start locking out other nutes. My neighbors use heavy 16 and canna and they are seeing great results. I personally use...

It really depends on a lot of things, like strain, grow style (like scrog), aggressiveness of the plant, etc. If your starting in veg I would wait until there is a considerable difference between the top 2/3rds and the bottom third. This way you have an idea of how thick the stems will be and...
