I cant get my irrigation setup to break the siphon. The system is as follows... foot valve > 1" pvc suction pipe > Leader 1/2hp pump > 30' of discharge pipe travels one floor below > manifold feeds (3) tables, each table has a pressure relief valve at the end of each loop. Room had 144 sites...

Please take a look at this photo. I'd estimate 5% of the fan leaves in the room look like this. This is in a new setup helping a friend out. He sprayed wettable sulfur 6 weeks prior to this photo being taken so there is the possibility this is actually sulfur. We spent a good hour scouting the...

I just setup a Leader Ecojet 1/2 jet pump that does not want to operate properly and I cant figure out what is the problem. Only thing I can think might be the cause is my suction line comes up and over the top of my reservoir and then down to the intake of the pump. I notice on most setups the...

I've got a plants that I should have moved into my flower room 2 weeks ago... currently almost at week 6, should have flipped at week 4. This is a new setup and flower room wasn't finished on time. I flip flop flower rooms so don't have the option to veg in my flower room and my veg room does...

Just setup a new spot and first time running a sealed veg room. Temps are between 73-78f at canopy level and humidity ranges from 75-85%. I've never run my plants this long. I do a 4 week veg so they do get big and bushy. Should I just roll with this high of humidity? Plants seem to love it...

I'm setting up a new room with a bunch of Gavita De fixtures. The manual says not to coil the cords but I see so many photos in IG where the receptacle is right next to the ballast, cord is coiled and plugged in very close to the ballast for a real clean look on the install. My room is setup...

I pulled an old Blue Ox 8 light co2 burner/generator out of storage. It's been there for almost a decade. Cleaned it up, removed the jets and cleaned them, fired it up and thing works perfectly... nice blue flame, zero delays to ignite. Only issue is it puts off slight smell, barely noticeable...

Well as the title says, I'm in the process of laying out the electrical in a new build. I've got 5 rows of 3 lights and if I can get 3 lights on 1 circuit it will make the layout look really clean. If I run a 20 amp breaker/circuit, and have (3) separate 15mp single outlet receptacles on this...

I want to start using Co2 in veg. I can get away without having to run an A/C if I use my drying/processing room as a lung room. Doing so will equalize Co2 levels in both rooms. So my question is, when I have whole plants in the lung room to dry, will a co2 level around 700-1000ppm effect the...

Will 800-1000ppm of co2 in a dry room cause issues to plants hanging in the room to dry/cure? Its a new setup, will be running LEDS in veg and I have a room adjacent to my veg room for my drying, processing and also housing my reservoirs. I want to run Co2 in veg and temps might be slightly too...

I plan to run 1800watts of LED's in a veg room that is 18'x18' with 8' ceilings. Room stays around 67 degrees all year long. I want to keep it sealed and burn Co2. Do you think I can get away without running an A/C?

So my friend has some coco from a grow he took down just about 10 years ago. Were talking a dozen 55gal drums of it. Its been sitting in garage, uncovered for all this time. I know he only used it twice before storing it and I don't see any old roots, smells fine, looks like brand new coco to...

I currently grow in pure coco, 2gal fabric pots, multi feeding. I'm getting tired of cleaning these fabric pots and thinking of making the switch to plastic pots. My concern is plants getting root bound. Fabric pots self prune but the hard shell pots won't. I'm 100% positive these plants will...

I'm sure many use DE lights for veg but couldnt find any specific info on vegging under DE HPS lighting. What is the veg footprint of a 1k Gavita DE? I plan to use (3) 1k Gavita DE fixtures for a dedicated 8'x16'. I'm going to start them off on the 600w setting but any idea how high I should...

Seems like you get a lot of bang for the buck with the Autopilot APC8200. 15' remote sensor, awesome display that shows co2 levels, dead-band setting, records min/hour/daily/weekly ppm levels, photocell etc. Comparable units are easily double the price of the Autopilot. Is this a reliable...

I never hear of people using Ozone generators to sterilize a room in-between runs. If what I'm reading on Ozone generators is accurate, your grow room and all equipment inside will be much more "clean" after running an ozone generator for a few hours compared to wiping everything down in...

I've read through the "cheap enzyme" thread and did a few searches on the topic of using pond-zymes. After reading that long thread there doesn't seem to be a conclusion to the debate. I'm interested in the API Pond-Zyme. 1 32oz bottle treats over 16000 gallons, safe on plants and fish. I've...

I'm blessed to be on city water that comes out of the tap @80ppm. I know the city treats with chlorine and not chloramine. I assume I'm wasting my money and tons of water installing a RO machine? I also need lots of water so were talking lots of waste. I'm thinking of just installing a...

Hello all... what is the best way to light up a 6'x16' space which is dedicated only for veg. I'm vegging out plants to 18" max so don't need the penetration, just the spread. I'm looking for something that can be dimmable and ideally daisy changed. I'm looking to spend about $2500... What...

Hello all.... I have a dedicated veg space in the basement. It's a 18'x18' room and stays at an ambient temp of around 60-64 degrees all year long. I want to run 3 or 4 SF-4000 lights over a 5'x16' table. Do you think these lights will get me into the mid to high 70's on their own or will I...
