    Hey guys, happy holidays for sure. My plants are getting a feast tonight to celebrate the birth of one of the most important men, if not the most important, in history. I'm talking of course about Isaac Newton. Happy celebration.

    I still have about 5 inches of space to move my lights up and the stretch is appearing to halt. They grew maybe a half inch since yesterday where as they were growing 1-2 inches every day before. I'm lovin the canopy I've gotten, might be a little too bushy horizontally though!

    As far as pros, they are the highest efficiency ACs you can use. With SEER (seasonal energy efficiency ratings) of over 95% efficiency. They are extremely quiet. No noise or vibrations. They allow you to run a sealed grow room because there is no air exchange. My room is about 8x10x8 and my...

    Been a great couple of days since that last 1.4 feeding. Today I began giving them their PK additive, since I'm all out of my PK 13/14 from CANNA and I wasn't in the mood to drive to the hydro store I substituted Ginormous from Humboldt Nutrients, which is a 0-18-16. 10 mL Coco A + B / gallon...

    Decided to go with a 1.4 EC today, backed it off to 9 mL A+B / gallon. Next 3-4 days they should finish their stretch and start asking for some PK, a request I shall satisfy. :-) Healthy 37 inches today.

    EC stands for electrical conductivity, basically all positively and negatively charged ions (in this case we're detecting dissolved fertilizer salts) conduct an electrical charge detected by the electrodes on our meters. TDS is calculated based off EC. There are different scales for TDS and...

    Since I haven't been getting run-off in the past 3 feedings or so I have to be very careful with my EC. I fed 10 mL A+B / gallon last time. Think I'll drop it to 8 for this feeding, then raise it back up to 10 and begin adding my PK. This should max out my my EC at around 1.7 - 1.8.

    First grow! Leaves curling a little & looking a little fried.

    The mold and the look of your plant are no coincidence. You are over watering your plant. As in watering too frequently, if you've been watering that pot completely through every other day that is definitely too frequent. It should be like every 4th day at the most with a plant that size.

    humidity prob

    Actually, colder air cannot hold as much water vapor as warmer air. Thus, as temperature decreases, the relative humidity will increase, and likewise, as temperature increases, the relative humidity will decrease. All this assumes no water vapor is added or subtracted from the air. TL/DR...

    36 inch average today, looks like they loved that 1.6 EC a few days ago. I'm gonna back off a little on my next feeding before I begin giving them their PK additive. Staked some more plants and used the rest of my stakes, may need to get more but I got the main colas for the most part...

    Right there with you bro. I think it is best that way. Like transplanting your plants, you shouldn't just start them in a 5 gallon pot as clones, you must gradually build up.

    It's week 2 day 2 and they're 32 inches and counting. Interestingly enough, I completely switched the two rear rows with my two front rows of plants. The plants closest to the wall in back were growing the biggest and fastest, probably because of the reflection off the poly. Anyway, I did a...

    The difference is Roots Excelurator is $75 or more for a 250 mL bottle. Rhizotonic is $65 for a Liter. That's why I've never bothered doing the math, Roots Excel is a concentrate. And I never really go overboard with the Rhizo, 8-10 mL/ gallon and I have bumpin roots Rhizo is a great help...

    Really pushing for that G / watt. 4 lbs would be on the dot. These WiFi's are super vigorous and if I've had any grow have the potential to give me a gram per watt it's this one.
