All right! Hydroponics is what I know, and hydroponics is the way I grow! :bigjoint:

This forum will be great, we can discuss anything hydro. No dirtbags here, We haul water!

We can compare the different nutrient salts, and all of the additives. Plus the kinds of soilless media and what irrigation system is best for each. And of course, pH and TDS measuring equipment, feeding and flushing, etc.

And all the while, we'll make fun of those guys hauling big bags of dirt! :blsmoke:


I can't think of any questions right now, what do YOU want to know?

water should be just below net cup, as roots grow, the water level should be lowered slightly more.

mix 1/4 to 1/2 the strength of what it says on bottle for “seedling” or “Veg growth”
if using tap, it could have calcium/magnesium in it already. If using distilled/RO water, you add in about 1-2ml/gallon or about 50-75ppm.
Add in your micro / formula mix A, stir.
Add in your grow / formula mix B, stir.
Add in your bloom / if using 3 part fertilizer, stir. Final ppl should be around 150-200ppm.
Increase as plant grows bigger.
3 part fertilizers should have a 3-2-1 rule.
Veg 3 parts grow, 2 part micro, 1 part bloom.
Bloom 3 part bloom, 2 part micro, 1 part grow.

Hey guys,
so i started my current NFT grow about 2 weeks ago. It is my first Hydro grow, i was using rockwool for about 3 years before.
I started my seeds in coco cubes and transfered them into the nft system after a week.

The roots werent long at all so I raised the water level so all of the cube is fully submerged in water. It is more like some kind of RDWC now.
Now I got signs of overwatering. Really slow growth. I thought that would not be possible in hydroponics? The plants are turning yellow from the top and are hanging down.
PH is stable 5.8 and water temperature is 20 degrees celsius. I use a small airstone in my reservoir but maybe it is not enough?

Is it bad to fully submerge the rockwool/coco cube in the water (maybe some DWC guys can help me out here)?

For something like that I would just throw some sprayers from above. People call them aeroponics, but they are really just NFT with low pressure sprayers for the most part. But they really do kick ass the first week or so.

Drop the water level you dont want the cube submerged, the water running past the bottom with cube sitting in it, the cube will soak the water up.

I am going to build a new nft system simular to the one i built a while back but larger for 12-15 plants

this looks so sick! how do you have the water going into the pipes though? is it recirculating somehow?

Yes i had a water pump in the res and pumped it in to the pipes and just recirculated, was a good little build for me i cant wait to get the stuff to build one for 12-15 plants, 3 tubes of either 4 or 5 each depending on space in the 2.4x1.2

Hi guys, big fan of the community!

I'm a first time grower and have build a dwc bucket system with a top drip line for the early stages. I was wondering If I should leave the waterpump on all the time or have it on a timed on/off schedule. Since it is a space bucket type configuration i'm only working with one plant submerged in the reservoir underneath it. I am worried that leaving the water pump for the drip line on all the time will warm up my reservoir too much for the roots to be healty. I'm sure many of you have used a "bubbleponics" setup so please help a newbie out, thanks!

I'm interested in a 4 bucket rdwc system, how nessecary is a chiller?
How much should I expect to spend to get a good set up? Thank you.
Would a 4x4 be big enough for 4×5 gallon buckets in this system?

I built a 4 bucket system in a 4x4 tent. I cut a hole at the bottom of the tent and installed an a/c unit. Cools the tent and blows directly at a bucket and my water is 72. Room is cooled to 75.

You can't see in the photo, but I've cut two holes in each kratky container - one hole to feed nutrient solution, one hole for overflow (because I don't want to overfill and drown the air-roots. These will be at 4 weeks since sprout this coming Tuesday. Soon I'll start tying them down (LST) hence the holes - I won't be able to remove them from the containers once they're tied down with twine and tape. Will probably give them only another 2 weeks in veg and then they'll go into my larger kratky bins and into the 12/12 tent :D
Happy July 4th from Canada bros!

Depends on the system bro I've done plenty of no flush grows and believe me I was dead against it for a long time until I started using Lucas's formula and recommended addbacks. you would think of course that some of the element salts would build up to toxic levels but it really doesn't come into play as you would thing when you properly manage your nutrient solutions. I will still recommend especially for beginners res changes every two weeks but not before that is only wasting nutrients as well as adding extra waste to the environment.

Nice to read that flushes aren’t always super critical. I’m about to start my first and will be going with the 10 day or so flush, but who knows, with an EC meter alone I can hopefully do add backs. Thanks for the every two weeks at first advice, this forum has been great so far.
