Hi, ! I've just joined up to share (and get some help with) this grow. No pics today, but here are the specs...
Strains: 2 Sour Diesel and 1 Holy Grail Kush, both by Reserva Privada about 4 weeks old but small, just fimmed this morning @5th internode.
Space: 3x3 Secret Jardin tent, kept open into very big room, LSTd for wire SCROG.
Lights: These did three weeks in Foxfarms coco loco, outside in the hot desert sun, showing awesome roots at repot in dwc the other day. Are under HydrogroLED for a few days before switching to Eye Hortilux 400watt HPS in the next couple of days, depending on heat. I'll need to get a cooltube setup soon if anyone can recommend a reasonable
How: Recirculating DWC, topdrip fed 15 on/45 min off. 3 3gal buckets, res outside tent.
Medium: I plugged the coco into Growstones in big net pots in 3 gallon buckets (may change to 5 gallon) w/ small airstone in each of the three grow buckets and in the res., which is same size.
Water: Rain catchment, soon to be RO that I'll be buying by the batch at 25c gal. I only need about 8-10gal per week for the moment.
Nutes: Using foxfarm Big Bloom, Grow Big, Tiger Bloom and have some Beastie Bloom, GH Cal-Mag and another chelated version of Mg. The ppms went up to 1900 from 15, I'm thinking from the drip over unrinsed medium, and they drank it down to 1200 over the first night.
Temps/RH: Air temps @68-84, res water 68-78, a tad high. RH in tent around 20-40, and I've got a little humidifier to bring that up some.
DWC scared the hell out of me, but the results I've seen others get outweighed the fear and here I am . A tad frazzled from checking the PH every hour I'm around the res. I've noticed a few things that are pushing me toward AN ph perfect nutes, just so I don't accidentally kill off the crop. One, the drip through the Growstones raised the ph about .5, so i needed to rinse them repeatedly to break their buffer. Once broke, it appears to stay broke and I didn't put the plants in until I'd run the system 24hrs and got stable numbas. But, as it seems ph goes up when they suck the nutes out of the mix, I wouldn't mind some extra ph security. Anyone tried these nutes for hydro/dwc?
Or have any other ph buffering experience with this sort of setup?
Thanks for taking a gander, I'll post some pics within the week. dwdude
