Well hi guys! I'm Nech, first diary here, not first grow though. The strain is a feminized photoperiod Whidak 47 from breeder Super Autos Seeds (Latitud Sur).
I always grow organic, using organic amendments as fertilizers. This substrate is a mixture of coco coir, perlite, regular soil, vermiculite, expanded clay, organic Bokashi, organic Compost, earthworm castings, Azomite, and seabird guano (manure).
I really can't say the exact proportions because I mixed it intuitively based on what seemed to make sense according to my experience. But basically grabbed a whole bunch of soil and coco coir as base, mixed it with a small batch of perlite, vermiculite, and expanded clay to improve aeration, and finally added the amendments. Some Bokashi, Compost, earthworm castings, Azomite, and seabird guano.
The idea of organic growing is to feed the soil, and the microbes in it, who then feed the plant. Overall I'm pretty confident it's going to work just fine, I've used similar substrates in the past that worked great. I don't think I under or overstepped with the nutrients (although it may happen, let's see). In each transplant, I'll be using Mykos mycorrhizae to reduce stress and improve root growth and nutrient uptake
Next time I'm going to document exactly the proportions of each compound in the mix but this time we'll have to roll with it.
As a light source these firsts weeks I'm using a Cobshop Autocob LED rated at 60W, hanging at 60cm (24"). Tent is a 60cm x 60 cm x 160cm (2" x 2" x 63")
I hope you enjoy this grow as I will, and I'm always welcome to questions and suggestions.

Being summer in my country this has been a pretty hot and dry week. Relative humidity ranged between 35% and 50% inside the tent and temperatures ranged between 26ºC to 31ºC and I'm using LED's, thankfully I'm not using HID bulbs. Despite the really low humidity and high temperatures these girls just kept growing.. They didn't seem to care at all. I'm pretty happy with the growth rate they've maintained. Let's see how they evolve.
@GuerrillaNo_4, Thankfully they're tough as nails, I hope they keep like that until harvest.
Yeah, I just saw your diary, maybe it's because Northern Lights are genetics usually resistant to cold, I never cultivated them in high heat environment. But in winter they handle it like pros. Great job tho! I'm sure your plants are gonna harvest a great deal.
@Nechmett, I'm amazed how well they are handling it. Just look at the burn on mine from 32'C, and mines a Northern Lights Auto cross, so fairly hardy genetics too
