Since I'm going to be running a lot of board in parallel I was thinking about using this box https://www.digikey.com/scripts/DkSearch/dksus.dll?Detail&itemSeq=263475743&uq=636644077762585632 . I can't decipher from the technical drawing if each terminal end is isolated or if they conduct...

I think that's where I picked up the idea to try it with 10 hours. The heads up is appreciated. It makes sense that messing with the hours of light exposure would also mess with a plant's genetic expression. So does anybody know which driver to use to power 22 Samsung LT-Q562A strips? They...

I really appreciate this insight. I’m probably going to either prove you correct and learn the hard way about applying an enhanced spectrum during the second half of flowering, or my hypothesis that it improves flavors, potency, and yields will be confirmed. I noticed that the median point...

I cut my coco with 15% compost (and 15% perlite) that is extremely high in calcium, also my water source is usually tap that has been allowed to dechlorinate by sitting for over 24 hours, and my base compost for my nutrient teas is Lobster compost, which is obviously rich in calcium, so tend to...

Thanks for your input. The SPYDRx PLUS I’m the study I linked to in my original post was measured by SMUD to be putting out 1323 PPFD at 6 inches with a CO2 concetration that went from 800PPM and maxed out at 1400PPM the RH was steady at 55% with steady temps of 80F so a VPD around 15-16. I know...

I'm going to be running CO2 at high PPM so I have the tent at 85F, and it would be inside a house that has central heat an air keep the temp at either 68 (winter) or 78 (summer). The math adds up to about 600w for 1.5 square meters. 2ftx4ft = .75 square meters x2.

I was thinking that. So far my choice of boards has been based on the efficacy of the chips. I've already emailed Cutter about them, and they did a simulation and came back with figures based on using 16 of the boards in a 4x4 So I would be pushing it towards the bottom of what Mark...

It would be two 2x4 trays stacked on top of each other in a tent. My target energy use is approximately 300 per tray. Think of it as adding a second story inside of the tent. I’m hoping that maybe I could get it lower. I was looking at the Q strips. 12 of them for the first half of flower so...

@nfhiggs is this the same F-Series strip you are talking about? https://www.digikey.com/products/en?mpart=SI-B8U201B20US&v=1510

Wassup RIU. New Account here. I used to grow a lot of good weed back in the day, but life happened and I had to stop. Now with it being legal here I've discovered that the quality of herb is going down and as my username implies I don't like that 30% of what I pay goes to taxes that are used to...

Here in California I view the budtenders similar to bartenders in regards to the specific knowledge they carry towards the products on their shelves, and for remembering me and my preferences. The local dispensary's budtenders actually remember that I prefer organic outdoor sativas and indoor...

The pot shop that is closest to where I live in California has $3.00 grams now. I bought a different $3.00 gram batch of White Grapes when I picked up a Strawberry Watermelon OG clone from them a week ago. It was ok. It works for rolling up in blunts or traditional mixed spliffs, but I wouldn't...

Why wouldn't somebody just buy a proven light such as a SPYDRx PLUS if they want to spent this much money on an led light?
