not really sure lol i bought it and figured it is full spectrum for plant growth so it would be fine.. im using a argo brite 125w and a hps 400w is this ok? thew hps is above and the argo brite is in the conner. is it better for flowering? will iut be ok to veg with? im gonna veg it untill middle of feb.once in awhile is fine, plus that will help keep a decent humidity level since there still in veg. Also, I noticed u said u are using an HPS light but u are in veg. is there a reason why u are using this light in veg?
