Take it from an old eye hortiluxe HPS disciple; COB LEDS kick major ass. Cheap-ass led panels are total junk; ok for vegging small plants but that’s about it. I found that COB LEDs on the other hand outperform even the most intense HPS bulbs. My Timber Redwood VS increased yields over my old 600w HPS no question hands down. It pulls the same amount of power from the wall yet it is dimmable. You can dial back to about 70% until the plants are in mid bloom which saves power. The lower buds get just as dense as the colas which means more solid nuggets curing in the jars. What used to be larf/popcorn is viable bud; more smoke instead of concentrate/edibles.
My advice? Wait until you can afford a quality LED from Timber or elsewhere. They really are worth the money.
Dick, you just have to work with what you have already paid for a decade before sometimes.
This fixer-upper house has projects that were priority so using time and resources to build out the proper grow room had to wait. It is what it is.
Since I expect Captain A-Hat to show up to Troll and Mock I'll post this update and then leave until I have the Seed Harvest. Remember that this is a Seed Rescue of 10 and 12 year old seeds. A wonderful Strain.
I will say that the choice to go with HPS and MH is the right choice for the conditions this Grow Room has going for it. Reusing heat or expelling heat is a net positive. So end of discussion on the lighting choice as I could give a S*** what people think. I know what is best for this room.
Now before we disrespect low wattage HPS have a look. Again I don't care what reader thinks.
All organic-composted soil. Liquid Fish is the only liquid feed other than water.
I now have the time, tools and parts to start adding ventilation, wiring, walls, etc and I am doing it at a time of year that I will truly have perspective on weather conditions here for this build. Too bad my Room Build is shut down or I could have shared much more.
I couldn't decide on Tank based C02 or using the LP burner so I have both. That should offer flexibility because the weather here fluctuates.. One day 60 F+ and tropical like rain then snap cold the next day and 30 F. A bit of extremes.
It is a Seed Grow:
Not bad to go from Solo-Cup challenge under CFLs to six foot tall plants under 250 watt HPS that are ready to be trained and flowered on a net under 4k of HPS and twin 250 MH for blended spectrum.
Best wishes to you all for High Holidays.
I'll post again when I am ready and A-Hat has finished spazzing out again.
