I have been growing for 3 years using a drip slab system with rockwool slabs, PBP full line, and Beneficial bacteria (plantacillin) with no problems.
I recently moved and acquired new equipment. My room is a micro climate with co2. I am running liquid cooled lights and a small window ac unit to keep the temps at 75 during the day and 65 at night. The mechanics and equipment of the room seem to be working great. I have included pictures of the room and of the largest clone.
This is the first time using an ebb and grow. It has 24 sites placed in 3 circles of 8 around each light. I am vertical with 3 1000k's)
I stated off my clones in an ez cloner and rooted all 30 in 7 days. With the first sign of roots, I added my bennies and superthrive. The roots blew up for a week, and then I added a light dose of Botanicare ferts. They looked great, and continued to blow up over the next week. I transplanted four days ago into my pre-washed hydroton and all seemed well. I mixed up some PBP, half strength bennies, superthrive, and ph to 5.8. and run the system every three hours for 15 minutes. After a few days my ph rose along with my ppms. The res smelled bad and white floaties were in it. It is the beginning of a bacteria infestation.
I am noticing how difficult it is to grow with hydro organics with hydroton as the medium. Since I have no rockwool and nothing for the bennies to culture to in the main reservoir, I think the bad bacteria is taking over the main reservoir, but since the bennies have cultured in the root zone, I believe they have not burdened the plants with rot yet. Since I can't run h202 with PBP, I switched it out for the BC that came with the unit.
Today, I refilled my reservoir with 45 gallons of dechlorinated 100ppm tap water, with only 25 ppms total of the BC line (no carbs) dutch master zone, and 1 tsp of h202 basically for a flush. I am sure this is going to kill all the bennies in the root zone of the plants, but will trade that for no bad bacteria any day! I am trading my wonderful hydroorganic ferts for chemical ferts to help ward off the bad stuff.
Any input would be awesome. Has anyone ever had this problem?
