When I received the mail from Gypsy Nirvana containing the unopened, pristinely packaged Sensi Northern Lights seeds in 2000, I had been cultivating cannabis indoors for almost 15 years and outdoors for almost 30. I sprouted my first seeds in 1970 after reading A Child's Garden of Grass but didn't really get plants to flowering until the next year when I bought A Connoisseurs Handbook of Marijuana.
A great friend of mine who was in the apprentice program to be a pipefitter (shout out to Local 522!) grew plants at his house in the backyard and when they got too big, we transplanted them to a remote area in Bernheim Forest. Unfortunately, it wasn't remote enough. We got ripped off. That wouldn't be the last time either, so the thought of growing indoors became intriguing.
With the purchase of The Grower's Guide in 1978, I began to experiment with indoor grows in my garage. I had some success but with the price, quality and availability of cannabis in South Florida, there were not a lot of motivational factors driving me other than curiosity. As the tall, rangy Jamaican Class IV/Sativa dominant hybrids grew, the Grow-lux WS VHO lights just didn't have enough energy to make it worth the trouble.
Also, living next door to a DEA agent (honest to God) made me think twice about growing but at that time, cannabis wasn't the main focus for the DEA, it had shifted to cocaine. And with just five or six plants, I knew he wouldn't really give a shit. The photo you see was taken with a Nikon F and processed at Fotomat (do a search on that), which is indicative of the general attitude regarding cannabis at that time in South Florida; it wasn't a big deal at all, I didn't have to worry about the Fotomat employee ratting me out to the narcs. They were more likely to say, "Damn, nice plants, how'd you grow ‘em?”.
When I hit the mountains in 81, I didn't get five acres but my couple of acres was on the edge of a fucking forest, so I was anxious to start growing outside again. I had to gain independence in all matters cannabis before I ran out of an lb I brought up from South Florida. I had a large garden area and sprouted seeds I had saved for many years.
The first crop was so much better than I had hoped for, 6-8 feet tall plants with colas that looked as good as on the Growers Guide cover! For the first time, I really needed the harvesting, curing and drying sections. I didn't get real good at differentiating males from females until the next year or two, a skill I would desperately need when I was forced to start growing indoors.
Taming tall, rangy sativa dominant cannabis to grow in a two foot by five foot enclosed closet with a six foot height restriction took a great deal of patience. Luckily, I had learned the skill of training a plant to grow sideways when I transitioned from growing in a garden to an overgrown hillside, in order to avoid aerial detection. I was doing LST before it had a name.
I essentially did the same thing in the closet, attaching string to the growing colas and securing to the sides of the 2X4 framing. Since they were getting lit by a 1kw MH light and had 450 CFM of air circulation, temperature was not a problem and there was minimal stretching when I sent them into flowering. As long as I gave them a normal amount of water and fertilizer, I didn't think I could go wrong.
I was wrong.
I found out during my first winter grow that humidity matters, very much so, although I didn't realize it at the time. As a respiratory therapist I know more about general gas laws such as Boyle's, Charles and Gay-Lussac's, in addition to absolute and relative humidity principals, than probably 99% of the population. That knowledge did not help me at all because I did not apply it to growing cannabis.
When young spouts are developing with high air velocity, they cannot tolerate 10-20% relative humidity levels for a long period of time, even if watered correctly and in the right temperature environment. It was very frustrating to have 20-30 seedlings sprout their first or second set of leaves then just fail to thrive. They would look great but just wouldn't grow and develop. By the time I realized something was wrong, it was much too late for any intervention. I wish I could say I determined what the problem was after that first grow, but I can't.
That would only come with experience and observation.
