Grafting, Cloning, DWC, Tent grow

Added too Much Golden tree this week causing root rot, which was quickly caught and fixed. Power bar kept on flipping off because I added a new humidifier which was was drawing too much power. Grow tent went down to 50 F because my heater was on the same power bar. Plants didnt seem too shocked , which suprised me . This has happened in the past and they became droopy . I am feeding more silica now and that seems to help keep them perky. I have been experimenting with grafting with a 50% success. My Cloning skills are getting better. It seems best to have a good routine when cloning , for me anyway. I have always been experimenting with different nutrients and additives , powder or liquid. Either way I listen to the plants watching the ppm . Once I find a stable ppm balance the PH will be stable too. I know that things are wrong when I get big swings in PH or PPM. Lately the PH has been dropping really low this is when I know I have too many Beneficial Microbes in my reservoir ,overpopulating and competing for resources with the plants . Ill change the tanks and keep a cup or two of the old beneficial guys to add back to the new solution. I ordered some alfalfa seeds which I would like to add to the top of my net pots for use as a cover crop. Right now I have a small dwc and a larger one the small one is at 225ppm PH 5.5-6.3 . the larger one is at 325 ppm same PH. I try to let the ph swing but is usually stable at 5.7-5.9 with the appropriate ppm. - For Lighting I am using 1000 watt Philips Hps bulb, running on a 600 watt ballast ( have been doing this for years no issues) The bulb is in a 6" glass air cooled tube . Connected to the tube is a 100 CFM inline fan (which is more than strong enough to do what I need). Hot air is routed out the window. - The tent is 48" wide, 24" deep , 6.5' tall The room my tent is in is very cold and un-insulated (its winter here). I run my intake fan and the heater on a digital thermostat controller . This allows me to keep the temperature within the proper threshold and conserves energy, saving on my hydro bill. Where I live we are charged time of use rates for hydro meaning at 7 in the morning we are charged more per hour because everybody is using the hydro at that time. So my lights turn on and off based off of our time of use chart. -Nutrients . Over the years I have built up a nice supply of free nutrients just by simply contacting companies and asking to try their product . sometimes these companies will have sample bottles that are not for sale but are given as free trial samples. So i mix and use different nutrients all the time most of them contain the same essential nutrients in the same or slightly different format Feel Free to ask any questions.. Thanks for viewing..
