So I'm looking to do a little experiment where I supplement my COBs with a string of a few different colors of monos. The ones I'm interested in all seem to run at the same current of 700ma which makes things easy. The different monos have slightly varying foreword voltages @700ma ranging from...

So for some reason I have only bought Mean Well "B" version drivers so far for my COB lights (maybe growmau5 recommends that somewhere in his videos...). These are constant current with dimming capability. I have a 1.4 amp one and a 1.05 amp one. Now that I am looking to add some COBs and...

Okay so this isn't my first COB setup but it's not a kit this time, I assembled all the parts myself, and it's not working. Here are the basics: Driver: Mean Well HLG-240H-C1050B [output voltage 236v, constant current] COBs: Citizen CLU048-1212C4 36v (actually it the Fv is 34.6v but let's...

Does anyone know of a fix or a way to get Hydrobuddy 1.4 or 1.5 to work in Windows 10? I really need this program. I have attached two screenshots, the first is what happens when I attempt to install version 1.5 and the second is after I successfully install version 1.4 but then it fails to...

Never had any problem like this but when I opened the lid of the rez, there were literally hundreds upon hundreds of fungus gnats both dead in the water and flying around on the underside of the lid. I have no idea how they got there. The system has no media whatsoever (no rockwool, perlite...

I was wondering if someone might help pinpoint what is going on here. These plants are about 2 weeks from harvest, and all of a sudden the leaves started looking like...well...burnt and very yellow. I know this usually happens late in flower but there must be something else going on here. All...

So I just wanted to throw this out there and get some feedback. About a year or so back I had dried a crop in a bit of an unconventional way and it resulted in the best bud I've ever produced. I have not been able to replicate these results to date. To summarize, I pretty much did everything...

I'm using large 50+ gallon plastic tubs from Home Depot to create a home made aero system where the the sprayers are fed in from the tops of the lids. The system works fine except for the one major annoyance - the lids leak.... well, more specifically, water seems to pool up in between the tiny...

I'm doing a little experiment just for fun to compare cloning in an aerocloner to cloning with nothing but a bucket of water with some air-stones in it. I have had clones sprout roots in nothing but a cup of fresh RO water that I change every day, so I don't see why this wouldn't work. I may...

So I'm in the market for a few new lights and love the new Gavitas, particularly bc they finally run off of 120v. What I am wondering is if I should get 1000w lamps and dim them down to about 750w for most of the grow, then kick them up when flower is in full swing? Or just get the 600/750 and...

So I just built a nice RDWC system and went to to fill some of the buckets and discovered that they are leaking around the bottoms of the Uniseals. I disassembled the thing, made sure it was dry, made sure there were no burrs or imperfections around the holes. They are round Home Depot buckets...

So I ordered a bottle of Protekt along with a few other things and the shipping box showed up the other day during a cold spell. I brought it inside but didn't open it until I got back home several hours later. When i finally did and picked up the bottle of Protekt, there was a frozen chunk when...

So I'm assembling an RDWC without air stones similar to the one in this thread: https://www.rollitup.org/dwc-bubbleponics/497270-how-rdwc-ucdwc-diy-advanced.html There will be hoses top feeding each bucket then the water is circulated in one way or another back to the control bucket. Here's...

So I'm building an under current system with a few buckets and I'm trying to construct a build which doesn't connect all buckets to one another with PVC pipe. Instead, there is a small 1 foot length of 1" dia PVC pipe inserted into the side of each bucket through a Uniseal. The PVC protrudes...

In reading a bunch of threads about the use of hydrogen peroxide in hydro applications, I had a few questions. I like the fact that it oxygenates roots and also keeps the water free of nasties. Most seem to advocate the use of 35% food grade H2O2 vs the 3% variety available in your average CVS...

So here's my dilemma, I am building a modular low pressure aero system with home depot buckets that I can add or subtract. There will be a central rez and pump (maybe 1,500 gph or so). Then running to each bucket will be 2 water lines of 1/2" O.D. clear poly tubing that I got from home depot. At...

I recently took cuttings of a few small plants in order to sex them. I put the in jars of plain RO water and stuck them in 12/12 for about 2-3 weeks. Usually I throw all of the cuttings out when I know the sex, but this time I was thinking, hey, maybe I should keep this male and harvest the 7-8...

I tend to buy my nutrients in bulk because it's a bit less hassle this way, but the containers are very ungainly for pouring small mL amounts. I always lose some solution because of the way the mouth of the container is designed - it dribbles down the side when I pour. I thought about pouring a...

The situation is this: I have several plants that are about 3 weeks into flower in a 6" PVC tube being misted in a LP aero setup. The plants have stretched ridiculously and have overgrown my light. The long and short of it is that I have small vegged plants of a different (better) strain that...

So I was wondering how you guys out here go about keeping track of your plants? I take a piece of Scotch tape, fold the ends over on themselves just slightly so there is a non sticky area that I can use to pull the tape apart, then sandwich the stem as I fold the tape in half, sticking it to...
