Again we grow

It's been a busy week. I have got some acoustic ducting. WARNING... Acoustic ducting has Fibre glass in it and is a MAJOR IRRITATENT to both skin and eyes and should be done in a well ventilated area with suitable protection. So, I have also switched from pure batmix to a 50/50 split with a good compost. I have done this as I'm not 100% happy with the level of water retention in the batmix, I'm finding it to be too much and I do not want to run into any issues. I would rather the soil drys out then I know exactly when to water. I have also increased the HPS to 400w (from 250w) it is very difficult to give plants too much light. I am spraying the tent whenever I can, with warm(ish) water to increase the humidity for a short while. I do have 1 plant that seems to be slightly stunted but I'm not worried just yet. I will be looking into fiming and LST probably next week to make sure they have a good base. I have also had to transplant the plants into another pot as the roots are growing like crazy at the moment. I also purchased a dimmer plug for the fan, as I don't need it to be on full all the time (it's a 6 inch fan with duel speed but thats far too much for what is needed now. Other than that all is good
