Welcome to my fourth grow! Dutch Dope has the highest percentage of sativa of any strain I've grown and, not surprisingly, it's also the tallest. While the first three strain heights ranged from 24" to 28", Dutch Dope tops out at 36", which is the absolute maximum plant height that my grow box can accommodate. I will be double topping again to manage grow height and maximize overall space utilization.
The grow setup remains mostly unchanged from the last grow apart from a single addition to the nutrient line-up of SNS 604A/B to round out the nutrient profile, otherwise lighting, medium and everything else remains the same. Even though I came close this last grow, I've still not been able to get a stable, problem-free grow under my belt, so I'm going back to the basics for this grow. The temperature will be kept under 85° at all times and, as a result, there will be no supplemental CO2. Due to the fact that I have no more space for grow/support equipment within the grow box, and given Colorado's semi-arid climate, there is very little need for dehumidification, so the best I will do is to ensure that the grow environment's RH does not drop below set minimums. These minimums are 60% for vegging and 40% for flowering, but during periods of high humidity, usually during the summer when the whole house evaporative cooler is running, I will just have to grin and bear it.
I will again employ GLR during vegetation as well as the inverted light schedule which worked very well in significantly reducing the impact of those hot summer days and should prove as effective in reducing the impact of those cold winter nights. Since this grow spans most of fall and the first half of winter, I'm planning on employing CFL sidelighting throughout the entire grow, as long as temperatures can be kept below 85°.
Today, I placed 6 Dutch Dope seeds into a glass of tap water. Within the next 24-48 hours, I expect to see some tap roots.
