Hi folks. I’m Matt and I love growing weed. I’ve been reading this forum a lot and learning from it so I figured I’d share mine. My first grow was textbook: got my lights from Amazon, used miracle grow, too small pot, etc. But after a year of coaxing it along and learning along the way I managed to get an ounce of very good flower. So invested in one of the spider-farmer grow tent kits, with the sf2000 ligh, 2x4 feet. Got some seeds, and planted them, and here I am now at 35 days. Sour diesel, Amnesia, Purple Kush left to right.
The plants are doing great, but it’s been some learning. My first grow got long and leggy really fast (given the span of a year), so I ended up bending it over like a candy cane, which surprisingly had the same effect as fimming, with lots of main branches growing out. So I wanted to keep these plants shorter. When the seedlings were ready for the tent I used the sf2000 dimmed to its lowest setting and it did a great job.
After they grew some more I wasn’t sure what to do about the brightness of the light. I didn’t want to hang it at 24 inches because I didn’t want things to get long too fast. So I kept it low, and I got a photone light meter app. I got set up with that and it said I needed a diffuser. I set up the diffuser and noticed that without the diffuser I was getting PPFD readings around 400 and 500, but as soon as I diffused the light I would get a reading like 1000 or 1100 or even higher. So I assumed the un diffused was correct since it seemed more in line with what I was expecting. So I went with that and my plants grew great, wide with big leaves but not real tall.
So for the last week I’ve been wondering why these plants don’t seem to be growing up, only wider. So I started thinking about it and the only thing I could think of is too much light too close. So I did another reading with the meter and went with the diffused reading which indicated that I was giving them “way too much light.” So I backed it off to the recommended range of around 500 PPFD with the lights around 24 inches now. That means the sf2000 is dimmed to around 40%. I topped them two days ago and pruned all the big leaves, they were the size of my hand. Everybody seems happy and the leaves are reaching a bit towards the light. Right now the main stalk of each is larger than a pencil, closer to two for the purple kush, and they are only around ten inches tall.
The bottom branches of the kush are almost as high as the main stem now topped).
My plan is to get a scrog net over them in the next week after they have gotten a bit taller. And hopefully flip to 12/12 around mid-May. The lighting issue is perplexing me because that sf2000 is really bright. Literally figuring out how to dial it in has been a bit of a challenge. Don’t know if anyone else has experience with them.
Well, thanks for looking. I’ll keep posting. Right now I am finding the hardest thing to do is leave them alone. But I certainly welcome insight.
