Well I have been wanting to do a grow log on my Medical grow for some time now and with Summertime and the growing season fast approaching, I figured now was as good a time as any. Well with that, lets get into it!!
The Plan: Over the last few years of growing both indoor and out and being a part of many other peoples' crops, I have grown quite an interest in greenhouses and light deprivation techniques. I've been wanting to built a light deprivation greenhouse in order to take full advantage of this beautiful Northern California summer by pulling two harvests a year. So this season I decided to go for it!
The Greenhouse: (Pictures Below) The greenhouse is a 14 foot by 8 foot rectangle PVC-framed blackout greenhouse with a roof sloping from 7 feet to about 5 feet and two support beams put a foot into the ground. To form a base for the PVC structure, I used 2"x10" pressure treated boards sunk and cemented about 4-6" in the ground and reinforced with 3/8"x24" rebar. The PVC structure is all 3/4" schedule 40. This frame is really ferakin' rigid. My wife can literally do pullups from the bars closest to the support beams, but it was designed to be able to support a 1000w for supplemental lighting, ballast and all. The whole exterior of the frame will be covered in a layer of 3.5 mil black visqueen. The whole interior will be lined with black/white "Panda" plastic for extra sun protection and interior light reflection. The top will be one layer of 3.5 mil black visqueen and then the whole box gets covered with a 40'x50' roof tarp. For ventialltion i'm using a ~300cfm snail-type exhaust fan with two 18" Oscillating fans inside. One section of one of the plastic walls will be the door, which will open like a flap and be connected to the frame with velcro.
The Plants: I am currently vegging 24 hours under a self-ballasted 150w hps and a few fluoro's here and there to help. I have 4 very healthy Afrweck clones, one kinda sickly Blue Dream cutting struggling to build roots, and one very robust Blackberry Kush seed. The one picture is the Afwrecks about two weeks ago on the day I got them. The other is yesterday, and shows the Af clones doing fucking awesome, as well as the sick BD and the baby Kush. I should be taking delivery on some 18 Grandaddy Purple clones by next week, all should be at least 6" and healthy. Once I get those i'll switch to my 600w hps to veg. As you can see from the pictures, the greenhouse has a trench-style bed dug out on one side and three holes dug on the other side. This bed is 13 feet long, three feet wide and about 18-24" deep. The holes are 2.5 feet in diameter and about 18 inches deep. The bed will be the home for the GDP and the 3 holes will be home to the Afwrecks, the Blue Dream, and the Kush.
The Goals: Hopefully, all 24 clones stay healthy and happy through about three more weeks of veg before they go in the ground. Every day ill open the top around 7am and close it around 7pm. With hard work, diligence, and a little luck (and no light leaks), I expect to pull 3+ pounds out of here for a mid-June harvest. At that time, i'll remove most of the plastic and plant the full-summer crop, which will be vegging indoors the whole time, and hopefully be 3+ feet by then.
Well thats about it for today! I will be updating this log with new pictures every few days to a week, so STAY TUNED! I hope to refer often to RIU and the vast copendium of knowledge contained therein Hope you all approve and if anyone has any questions/ideas/comments, feel free to contact me or post here. Wish me the best of luck RIU!
Thanks all and have a great day RIU! PEACE!
