    Heading into week 2. Added some Recharge to the top of the soil. They liked it last week, so doing it again.

    Yup, these aren’t stock Autopots. They’re “souped up” under the hood. Stealth SIPs.

    Did another tuck under the screen and flipped to flower on Tuesday. My cat, Jasper, approves.

    I don’t think it’s necessarily better. But you can get good consistency with the soil mix you do yourself. I think it’s actually a little bit cheaper too. When I say super soil, I’m really just referring to any potting soil with all of the amendments mixed throughout all the soil prior to...

    Do you find you get good wicking using super soil? I have always avoided super soil for fear it would be too dense and would either not wick as effectively or would allow the soil to become too wet in a SIPs. I may try pure compost or a super soil with my potatoes outside this year in their...

    Yes, indeed... Portland grower. I get the Down to Earth fertilizer at Portland Nursery. They carry their stuff. I've also used EB Stone. The local hydro store had Down to Earth for awhile, but no more. I tend to find the better organic products at the nursery rather than the grow store. Dennis'...

    How is your humidity right now? The reason I ask is my plant leaves would look like this when my humidity was below 50%. I started paying attention to the Vapor Pressure Deficit and getting my RH up to 70 - 75% with temps at 79 - 82F and I've noticed bigger, greener less twisted/ wrinkled leaves...

    I only top feed my SIPs. But, I make sure the dry ferts aren't simply poured on top of the soil or they won't break down properly. I scratch the new ferts in a bit to the top of the soil. Then I cover them with a bit of cow compost & worm castings. This should allow some of the feeder roots to...

    I’m taking the term medical grow very seriously. Hope you’re feeling okay. That’s actually nice the GG4 likes low nutes and lights. Saves a bit of money I suppose. It’s an “efficient” strain.

    I’m only running mine at 150 Watts right now. Will probably up it a bit once they’ve settled into the SIPs.

    They work great. I’m getting good moisture throughout, good wicking. I’m really glad I made the modifications. It will be interesting to see how it works out going from 250 watt light to 440 watt light as well. I got great flowers last time, but looking to up the yield a bit.

    Just transplanted a Critical Cure and Lemon OG into the SIPs. I’m trying a bit of EM-1 in addition to the bokashi I used last time. I’m curious to see if I get even more mycelium on the top of the compost this time.

    I keep my res out of the grow room and in a cool place with airstones. Airstones may or may not be needed. But I have them so I use them.

    COB LED DIY Build Journal

    I added a couple of case fans to cool the pin heatsinks. I mounted them at the side of the light case... they're blowing across the pins rather than down onto the pins. I had to switch out the fan driver to a bigger driver that could power the six computer fans. The fixture is ready to go for my...

    That’s great you’re growing your own seeds. What strains are you breeding? Are you using siblings for just a seed stash or are you trying to create a particular cross?

    5x5 LED - T-Time grow time

    The other thing I found annoying trying the TD Silent inline fans is they don't draw air like the centrifugal fans, especially when using a carbon filter. Centrifugal fans also do better than the inlines when you have bends in the ductwork.

    5x5 LED - T-Time grow time

    Yes, indeed. I had this problem with a wicking system and hydro. I like SIPs with plain water for this reason.
