thanks for the input guys. I'm still not sure which light to use though. the plants just aren't growing as well as i thought they should under the 1000 watt hps and i'm wondering if the light spectrum is not appropriate. I will probably switch back to the 400 watt mh and see if growth picks up. I have not grown this strain before (delahaze from paradise seeds) but i would be surprised if the lack of growth i am noticing was due to high temperatures. I am using a soil based from black gold organic and it seems like there might be too much fertilizer in the soil already. The leafs are not the dark solid green that I am used to at this stage. Any input is appreciated. thanks team
