I really liked the 315 cmh phillips master bulb, I think it was 3100k , I used it in veg and flower to reduce stretch, then tried the 4000k in veg and the 3100k in flower, more stretch. So depending on the strain I’d switch my veg bulb. The 315 out performed a 400 watt hps in flower. Under my metal halide in veg and hps in flower I averaged 1.2 grams per watt, the 315 cmh got 1.5 gpw and I was really happy, problem was the 315 kept going out after a year, under warrent I sent it in to get fixed multiple times. I’m now using led lighting I got a great deal on Amazon. Wer can I get the dj short blue berry? I usually order seeds at midsweeksong, to be honest I haven’t bought seeds or even looked in a few years. I’ve been finding my own crosses better than bought seed packs. right now I’m running a cross I made a few years back, it’s th seeds bubble gum crossed w a spliff blueberry. It’s a feminized cross I had pollen off the th seeds gum that I sprayed a branch w Tiresias mist. This cross is crystallized like crazy, not much gum or bb smell more skunk but it produces great! I planted 10 seeds all females of course, I was expecting variation,, all are identical uniform in height, structure, smell, taste and crystals galore. Making more S1’s soon.
