i have the more pricey boulderlamp 315 watt cdl agro, i shouldve shopped around as the sun system is cheaper but im happy.. i was used to my plants stretching going from mh in veg to hps in bloom and since i switched to cmh my plants are only 2ft tall and like them closer to 3ft, i increased my veg time and still plants are not as tall as with hps,but much closer nodes and tighter denser buds...
For strains/breeders I usually look around in here to see some grows/smoke reports before I buy, then check out the genetics on Seedfinder. That 210w bulb will run on the existing ballast in the Sun System LEC. I've run it a few times temporarily if I've had a small footprint but not a full run yet. I had bought it as a spare in case either of the 2x 315's goes on me.
I've mentioned this observation a few times since I started using these LEC's. The plants mature/grow faster than anything I've seen including COBs. Don't know what it is but it's pretty consistent across strains. I remember the first couple of runs with them having to adjust to the incredibly fast growth/maturation.
my th bubble gum under hps always took 56 days to finish, this run under the 315's they looked like i couldve pulled them at 45 days, thats over a week early.. anyways i switched to flush for the last week and thought well they will or should swell up.. im thinking i shouldve pulled they apear to look the same at day 53 as they did at day 45 exept a few more amber crystals.. next run is under hps but if i put them under cmh again ill plan for a 7 week flowering period and start the flush at 42 days then pull at 49 days...
I've been running them for a while so sometimes I forget about things like this as it becomes the norm. They take about 5-7 days off your cycle times on average. Any breeder times for me have come in at the low end or before across the board and strains I brought in when I started using them knocked off an average of 5 days easy. It ties back to how quick they set buds and mature the plants at the beginning of the cycle. When you're running perpetual you have to adjust for this or you'll break your cycle. Think about that in ROI, adds up to an extra cycle over a year
groerr,, any reason why? is it the spectrum or is it just as u said because the bud set comes on faster under cmh?? also why would bud set come on faster under cmh? it makes no sence to me..I've been running them for a while so sometimes I forget about things like this as it becomes the norm.

not sure why my plants finish faster under the cmh lamps,, spectrum alone doesnt seem like it could do that..maybe groerr has a point as they do start bud setting faster under cmh but still a week less to flower there has to be a good reason??? as for the dj short blue berry i ordered 5 feminized seeds and paid $125.00, 25 bucks per seed, none popped, i contacted the place i ordered them from and they gave me 125 dollars worth of other seeds but said that dj short would not replace them with 5 more dj short blue berries so the seed shop replaced them with other seeds of my choice from other seed companies as i have been ordering from them for a wile and we have a good buissness relationship.. i actually felt bad as they had to lose money replacing dj shorts bad quality..needless to say i will never buy dj short seeds again!!! i am finding out more and more that a higher price tag does NOT always mean better genetics or gear.. like how a 20 dollar plantmax bulb gives just as many gpw's as a 100.00 ushio bulb.. seeds are the same i can get 10 nirvana seeds for 30.00 and get 3 or 4 killer moms or pay 100.00 for 5 cali connection seeds and be lucky if 1 of them is a good mom... as you know i would need to buy like 50 fing seeds in hopes 1 resembles the write up and picture..it seems to me the picture and write up are worthless as you rarely if ever get a plant that resembles it.. we buy seeds based on that pic then have to do a phenio hunt and get lucky if the plant has 1 quality listed maybe the smell or structure or taste or yield but amost never more than 1 and never all the qualities listed... so what the hell are we paying for?? we are definitly not getting the plant in the picture and write up,, we pay in hopes of getting half the genetics listed i guess?..lol.. sorry i get pissed as i think all seeds should be uniform or stabilized so we get what we paid for...but many like the phenio hunting...
Only thing I can think of is the spectrum by process of elimination, ballast can make a bulb more efficient but it's not going to have any bearing on time, hoods can assist in spreading the light but aren't going to have that much effect. Grow style and medium are going to maybe affect yields but aren't going to have any significant effect on times.
Hey noticed I hadn't received a notification on this and missed it. The 210w is 3100k, only use them for flowering so this spectrum makes sense and the 315's have performed really well with this colour. Looking at the plant under the 210w last night and it's filled in/stretched normally, buds are now set at the same rate as under the 210w, not seeing any difference with this smaller footprint under the 210w.
TBH, I'd try 2x 210w in that 4x4'. That would still give you 26w/sq. ft. which is what I've run in a 3.5 x 3.5' with 1x 315w and pulled 13 zips. Your light spread will be better between the 2x LEC hoods. Of course it wouldn't hurt to mix 1x 315/1x 210w and you may see some improvement over 2x 210w. Looks like I'll be running 2x 210w for one cycle as I have only one decent plant to flower out next round so I'll have 2x 10gal plants under 2x LEC but running only 2x 210w, hmmm 2x210 = 420w, coincidence? lol
