this is my first indoor grow. I'm using soil as my medium and got a question. How long until I can start using nutrients on my plants. There should be enough food in the soil for atleast a month? Here's my mix I made this morning. 2 parts promix potting soil 1 part Perlite 1 part Worm castings 1 tbs/gallon blood meal 1 tbs/gallon bone meal 1 tbs/gallon Dolomite lime ( also thinking about adding some guano) So what you guys think. Am I missing anything in my soil.
Check out the organic forum.....tons of there about soil. One thing I see missing is rock dust. Another thing to note is mixed organic soil has to "cook" ( sit) for four to six weeks before use. If you go the organic route, and your pots are big enough, you don't need to add nutes at all. I have used pro mix as my medium for about a year in a hydroponic top feed system. I mixed perilite with it at 50/50 ratio and started feeding after three weeks or so. Note pro mix has a shot of fertilizer included and was too strong for young plants (tested the initial watering runoff at over 1000 PPM ) so I often flushed it till PPMs dropped to 300 or so). Also test the ph of the runoff as it is sometimes way off where u want it initially. I have swapped to hydroton as my medium recently as pro mix took a lot of babysitting to get it working properly G/L
I plan on doing a sog. I have 2 fem seedlings about a week old in the current soil (Barney's critical kush). These will be my mother plants. When they are big enough to clone I plan on vegging until they are 12" tall. So if you recommend waiting 3 months then I shouldn't bother with nutes at all? (veg approx 3 weeks + 60 flowering). With this hinder my yield at all without the help of flowering nutes. By the way my veg room is a 3x6 tent with 3 4' florescent t12 40w each. Flowering room is a 4x4 grow tent with a 600 Watt hps. Plan on having a constant harvest every 2 months with 16 clones (1 per square foot)
My veg room fluorescents are plant and aquarium 240w total. I will be using 1 gallon pots. I didn't plan on doing an all organic grow I just wanted a good starting soil to begin with. Little bit of poor planning on my part in letting the soil cook but atleast the clones will be in the cooked soil. I appreciate at the help I can get I am quickly learning that indoor is about more complicated than outdoor growing haha
