That picture was from before, maybe it was the angle and lighting and corresponding phone camera behaviour that makes it look different then the newer picture? I did make 2 groups of 600ppm, and 700ppm, to see differences in higher nutrient feeding. My tap water is 210, then maybe 10ppm for ph...

This was Taken on April 1, So Day 20 Flower. First Pictures I showed were day 30. This was yesterday, Day 35. 2 Days post HPS, 3 plants in the front are just finishing up on the outside for another week so ignore those.

I use the 1000 Hortilux super eye Bulbs. So thats what I have on them now, alongside the LEDS which are 2 of these, one on each end. https://www.alibaba.com/product-detail/Kingbrite-240W-Samsung-lm301b-v2-mix_62018007012.html?spm=a2700.7724857.normalList.22.3cf65be72Pdcj5 Also my nighttime...

I actually just picked one of those up! I can basically put it up as a wall, and its light enough to just slide out of the room into the hallway to get access. better than panda film that I used to roll up and move out of the way all the time, I think. I put mylar film on it.

Heya Mate! Thanks for the great post. Just the type of info I love getting. Actually growing in pro mix HP, so 70% peat moss, 30% perlite. Whats interesting about this run is I have 12 LGB clone, and have them in groups of 3. I put 4 into NEW promix, 4 into recycled/re used pro mix, and 4...

Thanks for sharing that, I will take a look, that's pretty much the other point of this thread, seeing if anyone else is running or has done some runs at 70F range with ok results. At first I thought it was a light leak, but I'm not getting any bananas.

I used to run at night for cooler temps. Now I run during days for hotter temps LOL. In my area electricity is a flat rate, inc. fees works out to $0.17 cad/ kwh

Main gripe is that they look like they are at 3 weeks, when they are at 5 weeks. In all aspects. I really wonder what would have happened if I didn't put the HPS back, and temps continued at 70F. How would they have turned out? At the rate they have been going it would have been not triple or...

Trying to make the air volume of the space smaller is challenging, because whatever you put up, you need to remove on a daily basis to get access. And unless its fairly air tight it is useless because my hurricane fan circulates air throughout the room fairly well. My game plan now is to use...

I will take a pic of the room today, since Im getting so many comments.

You def have a lot of LED Watts in that space. I always thought a 480w HLG550 is good for 4x4, but I suppose it can be pushed to 600 watts, Greenegenes has that setup I think. I also have this big room of 12x10 Feet. And it is an outside corner room, that gets no sunlight hitting its walls...

You mean to say, cmh has much less IR than HPS right? but agreed very similar to LED, I mean it is easy to understand that a 630W CMH puts out similar to 1000HPS, that 370W extra is all that IR and heat the HPS adds. But instead of seeing it as waste, I now appreciate it and know there is a time...

Yes I have ran this exact clone before. I would have remembered if it was scraggily thin and looking like a week 3 plant on week 5, I probably would have tossed it and not bothered running it again! Sorry I never heard low temps were good for LED. For HPS that has always been the battle and the...

Humidity is 55-60%. Like you said most likely that is what I need to do, run HPS/CMH in deep winter, HPS/LED in fall/spring, and CMH/LED in summer. Good thing I didn't sell my HPS's !!

According to that chart I am nailing VPD, 70-73F @ 55-65RH >:(

Yes full 100% dialed up. I know this because I was playing around with it in the beginning using my kill a watt. LEDS are 3K, room is 12F x 10F, the canopy area is 9F x 4F The reason temps start at 68, is because it is a corner room on the northside, and with the door closed with lights off...

I had the exhaust dialed down to 5-10% of the 1000CFM, its a 10" hyperfan, this was giving me 55-60RH, and I think that was pretty close to VPD when at 70F. Since then I have taken the Exhaust filter from the ceiling above the light, off to the side and a bit lower. I don't think it matters that...

See my previous post for explanation, my apologies. 1. This is a clone from the plant that I have grown before. So 100% identical. 2. LED high is 18-24", I try to shoot for 18" and readjust as they stretch into that. I grow in a row and had the 240W boards on the outside, and CMH in the...

I hope my delay in response will not hinder having a conversation around this topic. Even in quarantine, I have very busy days, and I only spend so much on social media, so it ends up being one session per day at most. Yesterday I spent that writing up the post, look forward to chatting with ya...
