I have been growing personal medical mj for a few crops now. I use a four foot, double "plant" bulbs to use on my clones, lighting for 24 hours the first week. I use cloning gel (I use Olivias) after letting my cuttings soak in my "secret solution" for a couple of hours. Then, I put my little ladies in peat pellets I have soaked in a batshit (guano) solution. Then I put the peat pots in the middle of a larger pot filled with ProMix, slightly covering the top of the peat pot. This has solved the problem of having the peat pots drying out too quickly. After a week or so under flourescents, they go under the big light, my 1000 watt halide, at 18-6 through the veg stage. I have just been given a 400 watt HPS. I am looking forward to expanding my little operation, allowing me to have plants at three different stages. I have never used sodium before, only Halide and flourescent. What's the difference? Anybody have any tips for me? I have grown some sweet, sweet Northern Lights hybrid, but am always looking to learn more. I use Super Thrive/batshit and some root and bloom stuff called "Garden of Hope. I have just been given some different stock...wish I could identify the strain. The leaves literally unfurl themselves, one segment at a time. I am getting a lot of big fat single leaves (as opposed to the threes, fives and sevens, I normally see with my Northern Lights). I must be doing something right. My plants are all getting lusher by the day. I like a shorter bushier plant than what a lot of my friends grow. I carefully pinch back from the time they are young, so I end up with at least four or five main stalks. Once they get to about two feet or so, I take shishkabob skewers and stake out the stalks, pulling them to the outer edge of the pot, so the inner part of the plant is getting good light, too.
