Now remember - this is in the bilge of a 36 ft boat. Please don't laugh too hard ;-) It's a 31 gallon garbage can - 21" dia. 27" overall height. It started in 1996 and evolved from a 70w hps to a 150w hps to a 150 cmh and now the HLG. As crude as it is , it has served me well.

This is first full run using my HLG v2 respc board which replaced a 150w CMH. Having a small cab in the bilge of my boat makes for interesting conditions. Primarily a lack of vertical height. Knowing the HLG is considerably more intense than the CMH I have been playing with the wattage to...

Renfro- THX for chiming in. We have known that HID bulbs will loose some of their juice over time. The specs on this bulb say it has a average life of 20K hours with Lumen maintenance of 89% after 2k hours and 79% at 5K hours. I was surprised to see such a drop in just 1000 hr. The test was...

I would venture to say that some new bulbs stay on the shelf for 7 years. I would expect no degradation of the bulb when not used. Not a perishable item. Now- I could be wrong as it happens often ;-) Speaking of the life of HPS's For 10 years plus I had a Phillips 150w CMH in a small...

I too inquired about their US shipping and where to order from- here is the response. " yes we do, but only strains from delicious seeds, world of seeds, or samsara seeds to US and Canada... Yes, order through this site

THX for that - I have used the Bloom on and off for years. Can you say KISS ? Giving Megacrop a whirl this time around.

Hmmm- I wonder why they did a color change ? Make it difficult or impossible to properly test the pH for those that use the GH pH colored vial test.

I ran into this article recently- found it interesting. https://www.alchimiaweb.com/blogen/move-marijuana-plants-outdoors/

Thx gentlemen- I had though of that route but I only paid $13 bucks for the fixture. Hoping to find a cheap option here. Should I be looking for a yellowish/ cream color filter or ?

I recently bought a LED fixture for the kitchen area in my boat. It was advertised as a warm light -12 volts and 9W. No mention to the component LEDs used. I disassembled the old ceiling light, installed the new LED and flipped the switch - WOW - just blinded by the blue brightness. I...

oops- forgot to add- I'm not very good at forums -sorry First photo was May 10 - CMH out - QB in Second photos are from today

I started to push the wattage and will keep a good eye on them - What is typically the first signs of too much light ? My temps are great - cab 77.5 tops 80 at 57% humidity. They are looking pretty good but the bub size is lacking this time around. 45-50 day stain with 14-16 days remaining

Barristan and pop22 - I could very well be terribly confused - If you would please look at this page - It lists the specs for the 288 rspec and has a lux to ppfd calculator for the 288 rspec. https://horticulturelightinggroup.com/blogs/calculators/converting-lux-to-ppfd Version Lumens*...

HLG's tests show a 288 V2 rspec board has a PPF of 1256. Using the HLG conversions for the V2 board a 1250 PPFD is 80,000 lux. I climbed into the bilge and did a few measurements to compared to the HLG site. Cranking the driver to 135w, using a Kill-A-Watt, at 12" from QB the app said 85K...

Ianc4990 - no room for that.

pop22- Thanks very much for the reply. First time using the Lux app on a Samsung phone. I was mainly using it to compare the QB to the 150w cmh I had in the cab. I have three new 150w cmh bulbs - all three measured 32K lux at 10" from bulb. I slid the new QB into the cab and get the 52K at...

Seems I did not do sufficient home work prior to purchasing my Q.B. 288v2 Rspec. It's total overkill for my space. 20" dia x 28" tall. Perhaps a DIY strip lighting setup would have been a better choice. Anyway- I have the 135w capable driver turned down to 55w which is giving me 52K Lux...

I too run a very small grow - 22" dia. and 28" total height. I used a 150 W CMH for years and just recently bought a HLG 288 V2 board. I didn't do enough home work and have found it is total overkill for my space. I replaced the CMH five days ago with the HLG turned down to 55 watts. At 10"...

You asked - Here are a few shots from deep dark dank bilge --- Note between the can and the engine - tan ballast box and carbon filter above it - About 16 days to harvest. This batch really stretched on me- I even had a heater on after the switch - keeping the temp the same as lights on...

Humple: Thanks very much for your reply- It was helpful. I will have to be diligent in keeping an eye on this new setup until it's dialed in. I would hate to roast a batch. Photos are a little hard to get in the bilge. If you can image- A home Depot 150w security light fixture...
