The girls are on week eight, almost ready to flip!. Had some problems with my clone/mother room this time round and the neem oil stress took its toll on the Pink NaPali clones. The Pink grew a little slower than usual. Looks like when I flip the lights the Pink will start it's stretch at about a foot shy of the rest of the crop. The Skunk, Gorilla and Wedding Cake is now touching the top metal trellis at four feet for some final light stress training. The plastic coated metal top trellis works well allowing the canopy to fill and makes pruning up easy before the stretch. The tide of this sea of green is coming in! Had a little problem here in the winter months with my last harvest. The ambient relative humidity got as low as 17% and buds got a little over dried. Hence, a humidor was built for this harvest! 😃 Tonight we will be flushing the roots with fresh R/O H2O. I will run the HP watering the normal 2 min./ 20 min. cycles but, will crank down the Ph down to 5.0 to help remove any salts on the root systems. The PPM rises.
While I'm waiting for this harvest, I am working on my fourth grow room. My first grow in 1989 was in an attic; a complete failure and a bust! My second room was a 16L X 6W x 6H. First grow, in that room, my plants drove right into lights and burnt all the buds. I ended up tossing that crop.
The next one worked out ok, after I had some help from a friend. My eight plant grow was using Coco for medium. When I read cannabis was a tracheophyte, I was done with the pot and started growing in the rails.
My floor is 10x20 but, the HVAC is taking up a bunch of floor space. I am building a shed attached to my room to hold the HVAC.
The new room will hold 140 net pots rather than the 80 now. This means I need more clones. My goal in the 10 x 20 room is an ounce per square foot. I'm only yielding an ounce per 2.4 square foot of valuable floor space at this time.
One of the cons of growing in the rails is you need a ton of clones. I'm basically just growing branches rather than plants. I purchased a 96 site cloner for over three hundred. Eighty clones were needed when I moved into my current room, 20L x 10W x 8H.
I didn't think over three hundred was worth the cloning machine, so I got some plastic and a pump and made my own 150 site machine. One hundred eighty bucks total, pump and all!👻
Finished the new rails for the remodel. After building the new clone machine I did not bother to buy pre-made rails. Good thing because the one's you can buy are too expensive and only 6 feet. These 8 footers will fit much better in 10 ft. room.
When the outdoor air dehumidification fan runs it produces a periotic negative pressure in the grow room. What is preferred: a negative or positive pressure in a grow room for this method of dehumidification?
Urrrrrmmm, not to sure what you mean, if we use 'passive' air flow then slight negative is preferred, the extractor fan creates negative pressure as it takes stagnant stale air out while 'sucking' fresh air in to create a cycle, to me personally unless it's sealed I would prefer negative so I 'know' it's pulling fresh air in, I wouldn't of thought this would be any different if you have a dehumidifier in the tent as well, you still want that 'fresh' air coming in, hope this helps happy growing 👍
