    It's nice to finally enjoy it and get to the gardening.

    COB LED DIY Build Journal

    Here's my first run so far under the DIY light. I ended up growing some Barney's Blue Cheese fem. Here they are at just over two weeks from germination. I went light with the Jacks 321 feedings and they were showing some deficiencies, so I've been giving them 1.7 EC - 850 PPM and they have...

    The CXA 3070 Saga continues....

    Thanks for the info. My medium is 50/50 coco-perlite. What PPM/ EC are you feeding at for what you consider 100% strength? I'm getting about 1.7 EC/ 850 PPM with a 3g, 2g,1g per gallon ratio. I've read some other growers going a bit higher grams per gallon to get the PPM even higher than this. I...

    The CXA 3070 Saga continues....

    Are you feeding Jacks 321 at every watering or do you do plain water between feedings? I am trying Jacks 321 and trying to get a sense of how much food the plants like in coco. I've been starting seedlings off at around 0.8 - 1.0 EC (400 - 500 ppm), but they almost look like they want more food.

    Sensi Seed suppliers

    The naming conventions for some of these "new" strains makes it quite confusing when trying to have an idea about the lineage and knowing what you're getting. So, I appreciate the classics and crosses that at least somewhat reference the parent strains in their names. I suppose a good portion of...

    New Loft Grow Room - Input Appreciated

    Hi Loftygoals, I'm a huge fan of SIPS for my outdoor vegetable garden. So, I'm going to try the Autopots for my cannabis grow closet because the system seems similar. How do you fill your reservoir? Do you let it get to almost the bottom and then fill it up again with water/ nutrient mix or do...

    I built the SCROG frame and bolted an attachment rail onto the wall for the clip-on oscillating fan. Okay, this thing is done. Time to start growing... finally! I didn't do an outdoor grow this year because I put all my energy into this project. So I'm anxious to grow again.

    Yeah, I tried the Soler Palau at both speeds. There was about a 17 degree difference between outside and inside temps at 100cfm. Temps came down to about a 13 degree difference between the basement and closet with the fan set at 135 cfm. The Can Fan and larger filter has my temps down to a 8...

    I built a reservoir stand and had a garbage can slider sitting around. So, I used it to hold the reservoir and slide the reservoir back into the reservoir closet. Nice and tidy.

    I've got my environment dialed in now with this grow light. The closet temperature is running right around 78F, 44% humidity. The fix was easier than I thought. I upgraded the fan to a Can Fan 4" HO (165 cfm) and I upsized my filter to a Can Lite 4". The fan is definitely more powerful than the...

    16 COB 848 Watt Grow - My Venture Into LED

    I like your SCROG net. What are those loops you attached to the PVC pipe to lace up the string? They look slick. Your plants look good!

    I need some ventilation help!

    Yeah, since I'm going to upgrade to a 6" fan then I think I will add another passive grill. I'm thinking i might go with a Can-Fan or Hurricane centrifugal fan. I think that might do better than the axial with any static pressure with the filter and ducts. Maybe go with 300-400 cfm fan and...

    Are the Vortex S-600 pretty quiet? Do you need to use a particular type of speed controller with it?

    Thanks for the quick response. Damn, that's what I was afraid of. Okay, I guess I need to sell this filter and fan and size up. I guess this trial and error stuff is pretty normal.

    I need some ventilation help!

    Okay, I need some help with my climate control and ventilation. I've fired up the COB grow light in the closet and have been running the oscillating fan and the inline fan and taking temperature readings in the closet and outside the closet. The closet is running a bit too hot at around 85F...
