    When to start compost tea

    Thanks for the info, Ruromo! But how YOUNG would you start? Would you give it to the guy in the picture or is it too soon? S

    When to start compost tea

    I've looked and can't find at what week people are starting compost tea. The plant below is a Future #1, and is an amazing 2 weeks from PLANTING THE SEED in the photo. TIA boys, happy growing!

    How I control VPD

    I went all out, dehum has a drain and hum feeds from my drip irrigation system. And just in case, the lights are on an temp controlled switch in case it all blows up at night. I work from home :)

    How I control VPD

    Youre good, I did. As I said in my post, the humidifier is powerful. It runs 3 minutes every 15 or so to restart the range. So its hardly constant. That said, I agree with higher temps. The reason Im where I am is because I have clones coming and I want the temp lower til they get some feet...

    How I control VPD

    The computer is from the pile of scrap I have, so yes, its free. The Interface in the picture is my home 70" TV. I watch TV on it so yeah. It didnt cost nuthin extra. Waterproof? WTF?

    How I control VPD

    Not sure why it should be waterproof. But the computer was in fact free, I have piles of old computers. The software took a day to write and months to tweak. I probably have what you describe. With about 15 mins of code I could include my drip irrigation. Ive experimented with controlling...

    How I control VPD

    Co2 sealed. The only way out is through the AC. Yeah, running hum and dehum seems wanky. But it works. I do not subscribe to the idea that running hi VPD during flowering is beneficial. Any VPD range that does not pass through 1.0 is useless. So says the science.

    How I control VPD

    Why would I pay for one when I can make one that does exactly what I want it to do? FREE? And I dare say... better? I've written code for 25+ years and make a lot of money at it.

    How I control VPD

    After struggling with this for months, I have hit on a solution that seems pretty close to perfect. I have an 8x8 sealed tent. I am running a Whynter ARC-14S set to 75 degrees (it's really at 69, but it translates to 75 average in the tent). I have a ALORAIR Storm LGR Extreme dehum that runs...

    Clone Temp/RH

    I think we are getting them already just rooted. So I'll follow advice and transition to a veg vpd (which would include the ranges you specify). I'm a software engineer. I wrote a program. I got some SensorProbe sensors, they have an API I can access to get RH and Temp readings once a minute...

    Clone Temp/RH

    We are acquiring some rooted clones. I've read a lot but am still unclear. What is the best temp/RH range for these plants? At what point to we switch to using VPD ranges? I have a sealed tent setup with enough HVAC to maintain any temp/RH/VPD range I want. That the result of some serious...

    Sick seedling

    I think there were a couple issues. I have a pair of Spider Farmer SF-4000s on them. I had them dimmed down to about 150 but the stems started stretching. I over compensated, up to 500. Not only that, but the seedlings are on a table and the lights were only about 20" above. I raised the lights...

    Recycled Organic Living Soil (ROLS) and No Till Thread

    Good info, I'm doing something very similar here. I have been lead to understand that the soil Ph isn't really monitored in no-til, the soil adjusts itself to what it needs. How accurate is that statement?
