Dr. Grinspoon

@neilmac1210, Thanks for the comment. There are a couple of things going usually; genetics and environment. I grow in a rockwool and have a very consistent technique I've used for years. Once you dial in rockwool/hydro it's always perfect....almost every time. Every once in a while, you get a strain or some genetics that just don't do well with 'normal' amounts of water. Of course, we usually discover the water sensitivity by getting droopy leaves with bent tips. The leaves never recover, but the plant can continue to live and develop, but it may also be stunted. Because I deviated from my usual technique a little and to see if I may have just gotten some bad genetics in that one seed, I popped another Grinspoon seed a few days ago. It is not stretching nearly as much as the one in the pictures. As far as why the stems/petioles/branches appear thinner than yours, I'm going to assume you are growing in soil. I've notice that my seedlings stretch a lot more when germinated in rockwool than when germinated in soil. It doesn't affect the overall productivity of the plant. There are some myths that I've been reading on the Internet for years. Seedlings stretching for light is one of them. They don't stretch for light. They stretch for other reasons. I know this because I have watched my plants stretch so much that they lay down on their sides for a few days. They stem just gets so long and white looking. After a few days, it darkens and the plant begins to stand up. This all happens under 400 watt MH lighting, so stretching for light? I don't think so. Anyhow, all of that stretch that can occur when the plant is a week to 10 days old,, will all be sucked back up into the plant, proportionally. 2 - 3 inches of stretch is nothing for a plant that will eventually be 3 - 6 feet high. These sativa genetics seem to not only take forever to finish in flower, but also take forever in veg. I happen to be growing a Neville's Haze side-by-side with the Grinspoon, and it is impeccable, in terms of any kind of blemishes or problems. The Neville's haze is also not a heavy drinker. I've grown some strains (skunk, chemdawg) that you just can't believe how much water is consumes as it is stretching. A 3 foot plant might consume 1.5 liters per day. Cannabis, more than many plants, will show drastically different phenotypes based on environmental input. Growing indoors and outdoors are not nearly the same thing, as far as how the plant is going to look, how big it is going to get, the quality and strength of the smoke, etc. One important thing to keep in mind is that the plant's need for water will changes. It will stop consuming a lot of water a few weeks before harvest. Also, if you defoliate, remember that removing leaves removes the plant's capacity to photosynthesize and it will not consume as much water after getting a haircut. Thanks for following my grow. 👍

@neilmac1210, Today the height is 170 cm and there are about 12 nodes (I removed a couple when it was a seedling). It's has stretched a lot and has started to flower. I hope it does not grow any higher, but I think will. I'm at my limit for headroom. I'm growing in rockwool slabs and feeding Flora Nova nutrients at about 1150-1250 ppm (250 of that is from the tap water). If you are growing in soil and/or using less than 600 watts HID, I'd expect your plant to grow a bit slower. My setup tends to finish plants at least a week ahead of schedule (what the breeder specifies).
