This is why White flies are disastrous for cannabis/marijuana.

by Alex Robles

White flies are tiny pest that could cause major problems for a cannabis plant.  I did battle with them back in 2018 and I learned a few things from a lot of different places.  I went back to my library and read everything I could find, I also went to some trusted online sources and I asked some fellow grower their advice.  Here’s what I think you should know about these little assholes.

Building A Grow Cabinet Part Two: Ventilation and Odor Control

by Alex Robles

When we decide to move our cannabis gardens indoors, ventilation and odor control should becomes very important parts of that plan.  In part one of this series I mentioned that when I build a cabinet I use the “Grow Cabinet Triangle” to make sure most of the big questions that come up are covered.  I’ve tried to put this basic information into bite size pieces that can be easily understood but that have to be considered before we put together a micro-grow or grow cabinet.  In this second part I’m going to go over the other two points of that triangle which are ventilation and odor control.  Some of you may think these are one in the same, but I like to split them up because I feel they’re equally important.

No solder computer fan hack.

by Alex Robles

Sometimes a little extra ventilation and air flow is needed in small grow cabinets that are used for sprouts, seedlings or clones.  When this comes up I like to use a computer fan for this job because they’re easy to hack and easy to find.  Below is a video of how I put a fan together without solder.   I hope it helps and let me know if you have any questions or comments.

by Alex Robles

Sometimes there are situation like prohibition or state regulations that make people have to take their cannabis gardens indoors.  When that happens space is usually limited and stealth is a must.  In these situation a grow cabinet is the perfect solution.  The beauty of growing in one of these is that we can make it as big or as small as we need it to be.  In the past I’ve used things that are already put together like a closet, locker or cupboard and other times I’ve had to build a custom cabinet.  This series will go over the basic information that has to be considered before we put together a micro-grow or grow cabinet.  I’ve tried to put this information into bite size pieces that can be easily understood but that have to be considered before we put together a small indoor grow space.

Something to think about for powdery mildew

by Alex Robles

What’s happening everyone, I hope your gardens are going as planned.  Lately when I get on Facebook, I’ve been seeing these ads for “Cleanlight Hobby Unit”.  The ad claims it’s a good tool to use against powdery mildew.  I have to say the ad made me curious enough to go to Amazon and look for some reviews.  I was surprised to see that the first review was from someone who not only hated this product but gives advice on how to build a better type of light.  It’s an awesome grow hack that I will be trying soon.  Check it out if you get a chance, it’s an interesting review.  That’s it, enjoy your day.

Growers Note:  Be very careful using any UV light for fungus control.  Some of these spectrums  have been known to cause skin cancer.  If you have to turn on the light while your in the room, cover up ALL parts of your skin.  Be smart and be safe.

Hack a transplant pot into an air pruning pot. a.k.a Rocketpot

by Alex Robles

Greetings fellow cultivators, I hope everyone’s day went well.  Today I’m going to talk about air pruning pots for a bit.  In the “Guide Book for Native Propagation” Julia Walker describes air pruning like this.

“Air pruning happens naturally when roots are exposed to air in the absence of high humidity.  The roots are effectively “burned” off, causing the plant to constantly produce new and healthy branching roots.  If roots are not exposed to air, they continue to grow around the container in a constricted pattern. Healthy, highly branched root structures allow a plant to more efficiently uptake water and nutrients while increasing growth and overall plant health.  A strong root system will make a plant better able to establish itself.”
