My latest lanky sativa i grew under a 135w kit. Day 40 flower. Unkown bag seed clone ive had for a while. It always gets big like this and its a pain in the ass but its very easy to trim and very efficient grower, not picky on nutes at all.

I think the rspec has more blue actually and they say that keeps things denser, and they say the 660 makes flowering faster. I thought we were trying to get away from blurple and pseudoscience but the overall efficiency and potential quality gains are worth it. I use 2x2s and im pretty much...

I got the 135W Rspecs when they came out and finished my last harvest under them. They were under a V1 before. Harvested early, about day 55 from flip, very early about 50% orange hairs, i have mold, humidity issues though. Top bud harvest was 130G. Bottom buds estimate about another 30g. I...

I cant understand what youre asking but just to bump. Im on 220V and i used a cheap 110V mechanical timer and it worked fine. I did for like a year before I thought about it, when it was "ON" it got very hot. I have a feeling a lot of these things are over designed and will work either way, but...

This is the new RSPEC after 1 week, earlier V2 3000k 120H. High temps, CO2. Maxibloom, tap water. Coco perlite. Standard 30 day veg and 12/12. Flipped it 10 may, will finish right after 1 july. Yield will be about 140g of solid bud and 50g of popcorn. Theres no purple stems. There is no "led...

This a mother under a V1 3000k 80H 24/0. Stems always turn purple under high light and slow growth. I've had it happen on revegs and on 12 week 13hr on flower cycle. Right now, its got nute burn because its gone into some slow growth after i trimmed, theres no deficiency or cold though, it...

Its not on though and it had been off for a while when i touched it. Ive touched it when its on plenty of times so im pretty sure its not a problem with the QB. Im on 220v EU standard, im starting to wonder if my circuits are actually grounded.

I just moved my set up and one of my QB kits shocked me a bit. Not bad but now im definetly not going near when its on. Someone let me know whats wrong. i was touching the top of the heatsink and my arm contacted the unpainted steel ball bearing in the connecting joint of my grow tent. Wasnt a...

Never heard anything like that before. Im not an electrician but my meanwell drivers seem to run almost exactly the same on 110 or 220. The way i interpreted the data sheet is that it will supply whatever you set the pot to and what the Board will pull. Apparently, the QB288 Lm301b pulls slighly...

Also, somebody correct me of im wrong but i believe you will gain efficiency at the board by dimming but youre going to lose efficiency at the driver. The difference after the trade off is probably negligible. Yoire just going to pay 150$ more for the 320 and youre going to dim it to a 260. get...

260 XL is perfect. i do a 120 in a 2x2x60 just top them and dont let them veg too long without training. I get a 120gram harvest. You could get more than 240, maybe 275 because youre not losing as much corner space and light reflected off the one wall. I would try to find some rigid wire like a...

I have a 2x2 dialed in perfectly for my needs. Ive gotten a 120gram harvest out of it every month for almost a year. im using the 135w kit with a fan attached. 2x2 is 53inches i think. Grow from seed and i top the plants at day 20 and start 12/12. At the end of harvest the top buds are 4-6...

Anyone tested the output side on HLG series drivers? I just hooked up a 80W and im not too impressed. Doesnt look half as bright as the 120s that they call a 135W kit and its 150 at the wall. Id bet a 120 is getting about 130 at the board and the 80 is getting less than 80. a bit misleading to...

My sugar leaves in the buds are dying. Been growing a while, same set up for a year. Coco/perlite, maxibloom. QB288 135W. Strain is unknown hybrid. Leaves are bleaching and wilting. ive had a lot of plants get closer on higher light with no problems and Ive had mold problems in the past but...

Has anyone tried active cooling with their quantum boards? i just ordered some thermal grease and a fan and it seems to be doing a lot better now. The heat sink and driver used to be just barely too hot to touch for more than a second, id estimate that to be 70c. Its still pretty damn hot but...

I grow in 2-2x2's with the 135W QB288 V1's and im extremely happy with them. Ive had them about 7 months and ive been able to put out a few crops. i measure my harvests in pint jars, which are usually around 18grams. The first run i got 7 jars, about 1gpw considering these 135's are actually 120...

I did a grow earlier in the winter with a 600W HPS, 180W LED, fans, air pump and other stuff. I was using about 1000W throughout my basement, and ended up tripping the GFCI occasionally, also had an issue in a separate part of the house with a heater burning up a whole socket. I didnt know much...

I understand the nonpolar thing a bit better but it still seems out of reach as i dont really have access to them. im going to investigate KLEEN-STRIP naptha. hopefully i dont go blind.

How does hash oil behave when combined with water? will it sink or float? If i was to add it to boiling water and stir it well, everything i dont want should dissolve right?

Basically, How do I turn Rick Simpson Oil into a more potent extract. I realize I may lose some terpenes though.
