I have a LumiGrow 650...bought it used off eBay. The Cadillac of blurples. That COB you have sounds great. So now I'm subbed as threatened. Bring on the fems! JD

And then once you get pollen...you use it to self pollinate the same plant. Way cool that you can do it selectively. You obviously don't have any issues with the micro-seed thing that causes popping when they burn. Several threads on that awhile back. I guess I better go sub to your...

It sounds fairly easy...though timing and silver dosage must be important. Good luck on that. I've never grown a fem...well till last week. Got some Kali Mist fem seeds as freebies...and well, what could I do. Not going to throw them out. So I have three at tiny seedling stage... JD

They recovered very nicely Zeus...good job. Keep us posted... JD

Good thought Renfro. Mostly I was wanting seeds to preserve the genetics for me. But why not improve things if I can. But all I have is their height difference at this point. I stroked the stems and they all had similar odors though a couple were way stronger...so I'm leaning in that...

It was an amazing concert too. At the outdoor stadium at San Diego State. Everybody was passing joints to complete strangers...that sort of concert. And Bob was doing his story telling through dance thing. Never spoke one word in the mike...only singing and to perfection. Beautiful sunny...

Why on earth would you? You just traumatized the plant and it will need the leaves for repair. They aren't blocking light...they are soaking it up for photosynthesis... JD

Hi guys, Just thought I'd post a follow up. Using two 315w with Philips ballasts. One light failed to start several times and also shut off if I bumped the reflector. I had done rewiring and modification of hoods so was suspecting a wiring issue. I swapped the bulbs and the problem followed...

Guy, If you have an EC tester...that's a start. That will tell you the total dissolved solids...but not what they are. And most municipalities will post their water district quality report on their website. When you try to do hydro with sub par water...you get problems just like you did. JD

Guy, You need to do a water evaluation thing. What water and how many minerals. Then determine if more Ca++ is needed. If you're ok on calcium...then Epsom salts are what most guys use. I'm in an awkward situation where I have to add half Epsom salts and half calmag to get both correct. You...

Hemp, Are asking if you should take fan leaves off the cutting? I usually remove fan leaves and branches except the top...but I do small clones. JD

That's an interesting idea...and will definitely take that into consideration. The seeds came from a fairly new op up in Alaska. don't know the exact story but they're old school AK growers. A RUI friend referred me to them. Alaska Cannabis Cache JD

Maybe that and the silica for right now...would be my suggestion. And you seem to be confused about your water. Spring water is just that. Not run through an RO. RO water that you buy at the store is usually listed as "drinking water" Your "Spring" water, if it has minerals in it, does not...

Good morning guys...finally got my camera operational and thought I'd try it out. I've been pondering this and thought I'd seek RUI opinions. I planted 11 Matanuska TF seeds awhile back. All popped and once they got big enough I topped them both for manifold training and to flower the clones...

Hi Sdyy, Don't know much about CO2 enrichment...but I assume those are reasonable levels. So lets ignore that for a second. FFOF is pretty hot soil and shouldn't need food for a month. So is that month up? Feeding with every feeding is for coco...not soil. Are you letting it dry between...

I keep my LumiGrow 650 at 3'...and ease in the reds slowly till I see plants like it. About 60% of it's output is red so I have a couple 315w cmh to balance out the spectrum. Good luck, JD

Guitarguy, Hey just a little aside...I played in a garage band back in HS. Had a classic Fender Telecaster that I bought for just under $300 in 1966. Hell of a guitar...bet it's worth thousands now.. It was the classic Fender off-white cream color. Coco once you recognize some of it's...

Fiddy, No you don't need a faster unit...just some storage bin to provide you with a couple of days reserve. You can even put a keep full float and valve. Fairly easy. Oh and comparing this water with your old water is more complicated then comparing ppms. But yes...most likely the...

Bf, Remember that you have .5 ec minerals in your water and always include that in your calculations. So say you want to add .5 ec of nutrients... that would give you EC 1. And look at all the other crap you're pouring in there. You're a beginner so cut yourself and the plant some slack and...

Hi cap, That's a pisser. I'm in a new room too. Bought a fairly powerful LED unit that's 600 like yours. Burnt my first crop. I was following the directions for the light. Whereas what I should have been doing is to dim it low and ease it up till it was doing it's job with no damage. I...
