Wow, can't believe I haven't updated my home thread since last November. Very sad on my part. Hoping I can keep up better moving forward.
So what's been going on down on the farm? I had a few less than desirable auto grows in my outdoor box through the spring and early summer. The problem was my grow medium. My local supplier stopped carrying Pro Mix HP, so I used some BX instead. Even with an additional 15 - 20% perlite it still wasn't drying out fast enough, sometimes taking over 2 weeks. As a result I couldn't keep them on a good feeding schedule and the plants really suffered. I had some Black Dragons, Sour Diesel Haze, Afghan Kush, Mohan Ram, Sweet Special, Sweet Coffee and White Sirius that yielded far less than what I'm used to. At least the potency was good. As an alternative to Pro Mix I tried some Bonnie Professional Potting mix. Same ingredients as Pro Mix minus the myco, sphagnum peat moss, perlite, lime and a wetting agent. I'm on my first full auto grow with it and so far the results look very good. I've shut down the outdoor box for the summer and have moved to my smaller indoor spot. I've got four 20 day old plants in it right now, a Sweet Trainwreck, Sweet Black Jack, a Spanish Diesel and a Pakistani Ryder, all looking very nice. I like that the starting pH of the Bonnie is 6.7 instead of the 7.0 of Pro Mix. With the lower starting pH I no longer need to add any aluminum sulfate to lower the pH. Feeding at 6.3 is keeping the soil pH right at 6.4.
I've also got my 3rd hydro grow going. Running some Lemon Kush from Female Seeds this time. They are on day 46 and looking very good. I also added some photo soil plants into the hydro room. These are being lit with some UNO T5 XHOs. So far I'm very impressed with them. At 110 watts per bulb, they are giving good penetration and good node spacing. They are in preflower and looking very nice. Unfortunately the new T5s are running a bit hotter than I anticipated. As a result, temps were hitting the low 90s and the hydro plants were suffering. When I designed the room I had planned on using all LEDs and sized my heat pump accordingly. As things stand now, I'm going to need to get a larger one if I want to continue running a closed environment. I've had to vent externally, which means no CO2. No point in running the burner if it's only going to get sucked out of the room. I had also bought some T5s to side light the LEDs. Again, because of the increased heat I can't install them yet.
I also just completed a modified SCROG for the hydro room. I built frames and stapled some cattle fencing to it. Two layers spaced 18" apart. I've not tied the branches down, instead am just redirecting the branches to spread them out and get more light to the lower buds. The frames are attached to some 4 x 4 uprights, two on each end. Each rack can be removed by taking off 4 bolts. I had tried using some cages I built from the same fencing, which is 48" high. The cages were a PITA to take on and off, plus if I put them on when they were really needed, I couldn't lower the lights enough. I think this will work out much better. One rack goes on when the plants are smaller, and the second once they get bigger. I'll get some pictures up so everyone can see the setup. I think it's going to work very well.
That's all the news for now. Hopefully I won't go another 9 months before the next update. Woops
