If you want high volume check out the GE Merlin. That thing can support a huge grow. Over 500 gallons per day for about $400 if I'm not mistaken. I use a 100gpd and it does about 70-75gpd for me. It does a damn good job by taking my water from 280ppm from the tap to 8ppm in my holding tank. I...

Moving your plants from your veg system to your flower system is no prob. Many people do this. Use a transition formula to take them from veg to flowering formulas gradually (first 2 weeks of flowering). The biggest tip is actually not to let them get too big. Flip um at 12" and they end up...

Pretty much. You may want to throw in some hydrotrom rocks or lava rocks into your net cups simply so that the clones don't tip over. You will also want to keep your water level right at the base of the net cups so that they get water while the plants become established. Otherwise, it's as...

OK, no one told you the trick. Here's how you get the mixture and the ppms right... the easy way. Take a small gallon container and fill it half way with the water you're using. Dump all of your nutes into this containner to get the percentages of your 1, 2, or 3 part formula correct. Now you're...

I just put them straight in hydrotron rocks in a net cup. The trick is to raise the water level in the DWC so that the net pots actually sit in the water a half inch - inch (depending on how deep you set the roots). This allows the small roots to get water and nutients while they get...

The biggest piece of advice I can give you is to take a good look at what your ventilation needs are, its the hardest part. What ever you think you need to vent the room, double it. Go with a bigger diameter blower all together. I run 6" blowers on my lights but 8" and up on my vents. Carbon...

Looks good. If your res temps come up you may want to consider silver tape or even just throwing some white towels down on the top of the lids. I've only had that problem under the 1k's but I've seen those t5ho setups and they seem like they's pack a pretty good punch for what they are. Once the...

Plants at this stage often don't look super healthy. Generally their newly rooted cuts and they're just getting their legs back. Give them a constant ph between 5.5 and 6.0 and a ppm of bout 400 or 500 ppms.Give them a week or so for new growth to start and the you can boast the nutes to 600...

It depends on how big your plants are. I was growig 3' topped plants and they'd use up most of the space (hudge dense mat of roots) in a 5 gal bucket by havest time.

I'd run 4 of the long air stones in each of those puppies. I've done somme experimenting and the amount of bubbles do make a difference. I've done 6 DWC's systems of all sizes and the biggest tip is to ditch the walmart pumps and get one of the biggest pisten pumps you can. You really can't have...

It could be a couple of things. It could be your water. You need to use RO if your tap is over 300ppm and then you's still need to run one of those hard water nute solutions like GH Micro for hard water. And yes, let it sit for at least 24 hours with bubbling it withe bubble wands to evaporate...

Doing a perpetual DWC is tough IMHO. In my large DWC systems I have all of the DWC's linked together. This makes water changes waaaaaay easier. You change the water once and it reachs the whole sysem. All the plants in the same system need to be on the same light/nute cycle. For example, you...

Looks cool. From previous experiements with the recirculating DWC systems, you may want to put the circulating pump on a timer and run it sparingly. It's going to raise your water temps a bit if you run it non stop. The first time I tried it I ran it 24x7 and I had a lot of root issues because...

It basically means your nutes are a little on the low side (ppm), which isn't bad unless they are way too low. You'll just need to do water changes more often so they aren't starving for food. If the ppms are rising as the water level lowers you are putting it too high to start with. The plants...
