Whats up icmag, This greenhouse was built on the lowest budget possible and is a prototype to test a few theories before i take things full scale.
First thing's first, this greenhouse is located in a heavily populated area, my neighbors aren't really cool with weed, there is also an ordinance in my city banning outdoor cultivation, the greenhouse un-permited I'm sure in violation of some code.
My goals are to be able to grow year round, i want to be able to harvest 4 times a year. i also have to contain the smell.
THE STRUCTURE
25x15x7.5
2x4's pvc and wiggle wire. very simple and cheap construction, it took one weekend to build.
the greenhouse is air tight, on one end there are 3x 12" canmax fans 1700cfm each. there are also three 6' carbon filters.
on the opposite end of the carbon filters there are 2x 20x30 house filters that act as passive intakes.
with just one fan running there is plenty of negative pressure and hopefully i will be able to control all the smell.
the temperature stays within 2deg of the outside temp with one fan running, i expect on the hotter days i will have to run all three fans to maintain the ambient temperature.
My main worry at this point is if the carbon filters will fail under humid conditions.
the greenhouse has already survived a ver strong windy storm and seems to be anchored properly.
The greenhouse plastic is 60% diffused plastic, it is translucent.
the dep tarp is 12mil reinforced poly.
The plants.
50 blue dream
30 backwater OG
3 gorilla glue
3 mendo breath
3 girl scout cookies
3 training day
3 cherry pie
3 xxx OG
the plants are all in 2 gallon pots
promix HP is the medium, Im hoping the plants won't get root bound in these small pots. my goal is 1/4-1/2lb per plant.
100 GPD R/O
Jacks 5-12-26
Calcium nitrate 15-0-0
PEKacid (drip clean)
Right now I'm feeding with every watering with runoff.
ph is 6.1-6.3 This may be a little low for promix, Any suggestions?
ec 1.2-1.4
i use a milwaukee TDS PH combo along with a truncheon, and a bluelab PH pen to double check all my values and make sure i don't make stupid mistakes. having both meters reading the same ph and ec values gives me a lot more confidence.
The plan is to set everything up on a drip system and trellis the entire greenhouse, hopefully the plants will be trained/pruned well enough that they won't need much assistance once they grow through the trellising.
Any input is appreciated.
Thanks.
