Hey kids. You miss me. A few things I have figured out with diy sips over the last couple years. .


1. Line your wicking pot with weed mat
2. Mix pumice and coco 50/50 in your wicking pot.
3. Layer the bottom of your main pot with 1/2 inch layer of pumice.

All this to prevent over saturation ^^^^

4. For the first month. Do not fill the resi!! Allow the roots to fill out the pot completely first. Then add water to the resi. This will make your roots grow insane. My roots fill out 75% of the resi.


Now I have ran with air stones and without. I prefer without stones now. Everytime I fill the resi I add a splash of labs. Make sure not to add more than a 1/4 cup of labs per 10 gallons of water.. Too much labs can go bad and stink. A little goes a long way. And keeps the watwr from going bad and prevents mold or harmful pathogens from hitting the roots.

Once every 10 days I top water with a mix of labs, ffj, yucca, and mammoth p. Then plain water the rest. The occasional sst. Never towards the end of flower. Cytokinins in sst's promote cell division causing longer flowering time and fox tailing.

Every 2 weeks i top dress a layer of gro kashi. Then once the layer of pseudomycelieum layer develops i top dress compost. Balance out the bacteria and fungi. I also have red wiggler worms in all my pots.


My favorite design is the fabric pot / octo pot design. I have not yet tried earth boxes. I have not wanted to spend the money as I've fully dialed in my diy sips.

Ah, Mr. Frampton. He's playing this summer down the street from me with Steve Miller Band. I don't own any of their music (haven't since it was on vinyl), but I bet I could sing along to most of their songs. It's kind of amazing how much they are charging for tickets to see a bunch of grandpa's playing songs they wrote 30 years ago...

Back where I was when I first started lol still more to do just the first but here goes nothing I understand in these I will water more frequently but for my current situation I feel this is what will work best. Can always upgrade or modify as needed but I'll be sipping again now :)

so it was decided YES we need a side hole at least one to allow air to transfer in and out of the res area?

All this talk about Res size , I thought i would get out the res for the new grow box and see if it measures up,, the Earthbox i grew in last time was wonderful, and i would recomend it for sure , but the 2.5 gallon res allowed me to go away for a short weekend over nighter, i was looking for a bigger res, but trying to keep it contained, to keep the "Easy Factor" going strong,
also the grow box has a lip that allows filling the res directly and a visual sight into the res as well, and now
So i measured 2 gallons into my green filling can, and its right to the rim, and the Res held right at 2 full cans, so 4 gallons i am very please with the res increase, and its still short at only 11 inches,
i tossed some leafs in the pic for visualIMG_0331.JPG IMG_0332.JPG

Ok, I got two of those garden boxes foxy posted above. I'm going to mix up some soil with build-a-soil's complete kit (30 pounds of nutrients and minerals) and use that.

My goal is to just put water into the res (and maybe some cal mag). I am not going organic. I'm going low maintenance. I have mothing against bottled nutes except for the complexity of custom blending every feed or water cycle. Plus not having to water as frequently will be a plus.

Sure, I'll have to top feed occasionally, but I'm hoping for much lower maintenance and a less hectic grow. I only have a 3x3 tent, so 2 plants in each would be a good number. Won't know till they sex out though.

2 plants fits well in the grow box and the earthbox, and YES to build a soil and water only,, my last 2 grows were water only just cal mag,, talk about easy,, easy makes growing fun, more time to sit with the plants and crank some johnny cash, and pretend i am in hawaii with the bright light,, hahaha

Healthy plants, happy plants. They're entering week 2 of flower now in the SIPs. The stretch has been manageable so far. The screen is full, so any more stretch will go vertical. These plants are pretty bushy, so I will need to do some significant thinning of the lower fan leaves to open things up a bit. I need to get the humidity down, with all the leaves the plants are transpiring a lot of water. Week 2.jpg

Looks great! I've been in the same boat (extra thick canopy + humidity), a couple of times its led to PM. Make sure you have tons of air movement and thinning is really important if your humidity is high, but it sounds like you are on top of that.

I have a fan on above and below the canopy. I know if I turn my exhaust fan on continuously I can get my humidity down to 55%. The only problem is running my exhaust continuously will drop my temps down to around 75 - 77F which is a bit cool. I'd like to keep my temps up in the low 80's if possible. So I'm in a bit of a pickle. I bet when and if I add a few more COBs to my light I will get a bit more heat and my exhaust fan would kick on more often and also take care of the extra humidity. But right now I'm stuck. At some point I may just run the exhaust full time and accept the lower temps.
