My second crop is hydro, bubbler. I used to grow in dirt at my pad in Chino Hill Ca. had a little greenhouse, 6 foot ceiling, had to tie them down as they grew to an astounding 12-15 ft. Was bag seed and was some pretty decent smoke, lots of cow dung for ferts. I grew one dirt grow in my closet, got 6 plants WW and they didn't flower very pretty, but they were potent. Am into my second attempt with the bubbler. Killed the first batch off trying to adjust PH with bleach and vinegar. My tap water I used on first grow was 650particles to start, with nutes that put it at 1400, so it was fubared to start. The plants got about 6 inches tall really fast then when I started adjusting they got sick. I yanked them, washed the bubbler out with bleach, rinsed well and started over. I'm now at about 10 days from seed with rock wool and growrocks, Ph-5.8-6.4 PPm 650-750 using pure water that I get at the water store for 16 cents a gallon, PPm 6-10. a 10 gallon bubbler with 6-3in. pots and the plants are approaching 6in. tall, they were slow to start, but you can almost watch them grow now. They are growing at an alarming rate compared to the soil grow. at this rate, I'll be putting them into flower within a week, already on the 3rd nodes. Maybe soil tastes better, I remember the Panama red, that is absolutely the best weed I ever smoked and believe me, I've smoked about every kind you can imagine. The second best was Cambodian red, you don't hear much about that, but my brother who was in Viet nam brought some back on a leave and gave me an Oz. man that thing lasted me for over a month, 2 tokes and you were history. I used to roll small pinners and fire them up and forget where I put them after two tokes, I'm sure you can relate.
