Which would produce more DO in a DWC?

Hydroponics / Aeroponics Which would produce more DO in a DWC? I've got an Active Aqua 60W, 70 L/min pump coming for my 4x5 gallon bucket UnderCurrent build. An 8 output manifold comes with it. What I'm wondering is, would 2 air stones per bucket produce more dissolved oxygen than 1 air stone per bucket at twice the pressure (because 4 of the outputs would be shut off)? more info...

Food grade barrels with smell safe to use for holding tank?

Hydroponics / Aeroponics Food grade barrels with smell safe to use for holding tank? I have 2 food grade 55 gallon drums I got cheap off a local guy. He used them as rain barrels for many years but they still smell like the soda syrup that he said was originally stored in them. I cant remember exactly how long he used them.. 10+ years at least. Do I need to be concerned about stuff leeching out into my water or should I try to clean them more? I was going to put them out back to collect the RO waste water but plans changed. I have a large holding tank already, but I was... Food grade barrels with smell safe to use for holding tank? more info...

Question about upping nutrients as plants grow.

Hydroponics / Aeroponics Question about upping nutrients as plants grow. Hello. I have a couple Mama Mia's that are about 22 days or so from seed in a rdwc. I have been feeding them around 150ppm for a week and they seem to be growing well. My base water is 150ppm for a total of 300ppm. My nutrients have stayed at 300ppm steady all week. PH has stayed at 5.7-5.9 all week and I have not adjusted it yet. I am going to do a res change in a couple of days and was wondering if I should stick with 150ppm? A better question would be how do you know when to increase... Question about upping nutrients as plants grow. more info...

Leakless RDWC

Hydroponics / Aeroponics Leakless RDWC Hey everyone! I’m starting a new grow soon, and I was wondering if anybody had ideas on how to create an RDWC system that doesn’t involve drilling holes in buckets. I’ve been down that road before, and it usually leaks. Don’t want to chance it I my new apartment! I was thinking some kind of top feed system would be best, but I’m not sure how to drain each bucket. Thoughts? more info...

Chilling several rez

Hydroponics / Aeroponics Chilling several rez I run titan flow and gro setups. I usually have 4 systems in flower, another in veg and a flood and drain table for early clones. So thats 6 50 gallon rez. I'm seeing water temps up at 78f lately. I started dropping old PH jugs of frozen water in them for now but thats not doing a whole lot and I have to change them every 8 hours to do much of anything. So it looks like I need to buy a chiller. I will soon be moving the setup to the basement so the rez and buckets will be on... Chilling several rez more info...

the issue with Lucas formula

Hydroponics / Aeroponics the issue with Lucas formula While I find the Lucas formula good for sativa-dominant plants (ie fast growers and heavy feeders), when using it with light feeders plants (either whole breeds or particular individuals of a breed) it walways ends up in nitrogen deficiency. This becomes particularly evident when using high intensity lights with UV component such as COB LEDs I believe this happens because the 5ml micro/10ml bloom (per gal) formula supposedly to be used in veg is too strong for certain strains at the earlier... the issue with Lucas formula more info...

The Membrane Meniscus System

Hydroponics / Aeroponics The Membrane Meniscus System Hey everyone, after reading about the membrane meniscus hydroponic system on Larry3215's thread: https://www.rollitup.org/t/three-types-of-hydro-in-a-small-tent-on-one-airpump.960095/ I did a little digging, got in touch with the inventor Andrew Parker and also read his book on the system. On paper it seemed like the next step in hydroponic systems as it claimed to be a recirculating system where the PH and EC dont change throughout the grow, the roots get the maximum amount of...

First time hydro, going to try Ebb/Flow - is this a reasonable plan?

Hydroponics / Aeroponics First time hydro, going to try Ebb/Flow - is this a reasonable plan? Hello everyone! I am hoping to get some feedback on my first ever hydro plans. Im in the final weeks of my first MJ grow in soil and its going pretty well. I have decided that I want to try a hydro grow next time around. After tons of reading, I have decided to try an ebb/flow setup with two plants in scrog. My grow tent is roughly 7 sq ft (28”x38”x48”tall) and I have a 300 watts LED light fixture using 3500k Solstrips (the same led’s as in Quantum Boards). I have read a ton of threads and...

ph probe protector

Hydroponics / Aeroponics ph probe protector Wanted to share my idea about how I protect my glass on my ph probe that always stays in my barrel. If you use one of these you need to do this. I just used a torch, vice grips and a nail to poke the holes in it on all the sides and make sure you put holes in the bottom so the water can drain out when you pull it out your rez. I trimmed up an old toothbrush to fit in the top to clean it. View attachment 4058240 View attachment 4058243 more info...

1st DIY Hydroponics Build; Mike Huntherz

Hydroponics / Aeroponics 1st DIY Hydroponics Build; Mike Huntherz I guess this is bubbleponics? Top-fed RDWC? I am making this shit up. I have a control reservoir on the left with a very small return sump, which is split four ways into three little drippers buried in the hydroton (pulled out to show in one photo) of each bucket. Each grow bucket also has an airstone which are attached to a sizeable airpump rated for a 60-100 gallon aquarium. I repurposed a few Blumat parts I had laying around for the drippers.

Harvest a Pound Every Three Weeks!

Hydroponics / Aeroponics Harvest a Pound Every Three Weeks! Outdoor growers are heading inside now so I thought if might be a good time to start a thread on how you can harvest a pound every three weeks from a 7x8' closet. I'll take you through my process from start to harvest. What is different about my system vs. others? 1) 3 separate Aero/NFT flower systems allow me to run a 9 week flower cycle. This allows the buds to fully ripen and also allows me to run strains with more Sativa in them. 2) I... Harvest a Pound Every Three Weeks! more info...

Flushing a myth??? Or a Mystery???

Hydroponics / Aeroponics Flushing a myth??? Or a Mystery??? So as the title says Flushing a myth??? Or a Mystery??? Is flushing or not flushing a cannabis plant actually beneficial to flavor, weight, and potency? When i refer to flushing i mean cutting off nutrients and feeding just water or a flushing agent for a period of time before harvest. Im hoping we can have a civilized conversation about this based on facts and reason. No false equivalency!!!!!!
