Hello All, you are welcome to post comments and pictures on my Journal. This is a legal medical grow. I live at 5,000ft, we have over 30 degree temp. change most days. The Rh can be 80 percent one day and the winds come and 5 percent the next. I am life long construction worker, because of weed. So I built my grow boxes to some things I learn along the way. I have roof venting instead of forced fan removal. I lined my box with Low-e reflective radiant heat barrier insulation. This stuff is how I handle the heat swings and rh problem, plus it refects my light, 400w hps and cfls I use in my smaller box. I am using a soil mix of my own design. I will be changing to Coco base " super soil" next week. No more mixing nutes, just water and molasses. A top dressing is used at start of serious flowering. Now my method of growing, 12/12 from seed. The advantages of this method are: able to sex regular seed in 3 to 5 weeks,smaller plant, thru pot sizes. You can use one box for everything and save power. You grow single cola indicas and super crop sativa. I have clones because people give them to me, you have veg a clone at least 10 days or it won't get any size. Perpetual because I smoke a lot weed, mostly with 20 somethings. When you get older 80 percent of people you smoked with in your 20"s will quit by the time your 30. I like to harvest something every couple of weeks. I am posting pictures of where I am at last night, plus a harvest of Purple Haze Clone One vegged and one not you can which is which.
