This week I've included a shopping list for a second 300W COB light that I'm going to add to my tent when I make the flip, hopefully on April 1. Here's a lesson for those who want to build their own LED lights: give yourself enough time to order and receive all the parts you need. To spread out the cost of my setup, I started veg with a 300W COB setup and planned to build a second one in time for flowering. Late last week I repeated my online order with Component Distributors, Inc. (USA Citizen COB distributor) but the Citizen 048-1212 3500K COBs, heat sinks and power supply were out of stock, with estimated delivery times from 2 to 6 weeks. I tried to find COBs at other temperature values and they were all out of stock. So I turned to Alibaba and made an order with KingBrite in China. I had to get 3000K COBs because 3500K and 4000K were out of stock. So I'll have a little more red in my flowering setup which may not be a bad thing.
Speaking of red, I have done some reading on the subject and decided to add a small array of 730nm far red LEDs to manipulate phytochrome state and put the girls to sleep ~1.5 hours before they normally would. This should allow me to either shorten up my flower time under 12/12 or allow me to keep the flowering time about the same under 13/11 while increasing yield by about 8%. So I have ordered the parts I need to build this far red LED lamp.
I bumped up the thermostat on my electric heater a bit and have achieved a fairly steady 72-75F temperature in the tent, and I think the plants are responding favorably. As an energy efficiency freak I don't like the idea of using supplemental electric heat, but the unit is on its lowest power setting and doesn't run frequently, so the benefit clearly outweighs the cost. The Vortex is looking and smelling really interesting. Bagseed looks and smells very promising. The White Widow isn't doing much for me in veg stage, but they are healthy and bushy.
While I'm waiting for my light components to arrive, I changed nutes again and addressed some of the overcrowding on the two buckets (front left) that each have 3 plants. I did some defoliating and HST. The plants rebounded well, and actually pulled up the training softwire that I had taped down to the bucket lids with Gorilla tape. The plants won the training battle! They're pretty much recovered and ready to start flowering as soon as I add my light.
Great advice and feedback from all. Thanks.
@OldCoolSativa, I am by no means a pro, but I usually start lst week 3,4, maybe 5, so by flower stretch her branching is already moved and stable in the new way I have it growing. I would say just get in there!! You never know till you do, but it's a lot harder when she starts getting woody. Stresses em more I think. Your gonna love it!!
@HydroKitty, I've already done a little defol but should probably do some more this week. The internode spacing is small enough that I don't think I need much LST yet. But since I've never done LST before, I could be wrong. π Thanks for stopping by.
Ideal day temp is 25C and the bigger they get the less humidity they like - the difference between the day and night temperatures will affect the distance between the nodes - all look nice and green π
Nice grow Bro. Regarding ur week 5 update, I bought my whole setup from kingbriteled, you shouldn't have any problem with them. If you use 2 different fixture for veg and flo why didn't u choose 4000k and 2700k? Just curious.I stopped at cobs' basics but will research some info about adding 730nm diodes, maybe I'll add some for the next grow. Keep us update man!
@Nutria, I just looked on Ebay for 730nm and found a USA seller. Specs are 3W 20mm Star LED, 720-730nm, 1.5V - 1.7V, 600 mA - 700 mA, 40 LM, 120 degree viewing angle. I'm going to run them in a single 3-ft strip in the middle of my tent between my two lights. I plan to turn them on 5 minutes before lights out and turn them off 15 minutes after lights out. This should allow me to use more light during the flower cycle. I plan to go 600W 12/12 for the first week of flower or until the girls reveal themselves. Then I'll ramp up to 13.5/10.5 for most of the flowering period, then back it down to 12/12 for the last week or two to finish them off.
@@Kkkkkk, thanks for the heads up. I have a couple circulation fans in there and all the plants leaves move around in the breeze a bit so I think ventilation is OK for now.
I have a similar problem. I am on week 6. A bit slow for sure in the beginning. Temps are usually above 26 and up to 32 someone time. But my plants are stubby and wide. But since this is my first grow, I thought maybe it has to do with the strain? Can someone with experience check out my grow? thanks man.
Your guy is right.
The temp is way to low!
You need constant 25 grad celsius.
And your air humandity was to low, thats why you leafs looking squishy.
But at all it looks very good.
Wish you much luck and awaiting interessted what you get out. ;)
Keep on. ;)
@KonopCh, I found them in bags of weed from a Deadhead friend, reportedly grown in Western Massachusetts. They germinated easily...hardly any duds. I germinated them in Rapid Rooters.
@BigDaddyK, good question. It has been pretty high, like upwards of 80% at the end of the day. Condensation on tent walls, etc. Today I finally set up a blower and charcoal filter and humidity is down around 60%. Running a dehumidifer in the basement to help keep things under control.
hey man nice grow. i tried a bagseed in my grow, it's in my current journal. it was a herm :(glad you got away with it. this is twice i had bag seed herms so be careful using bagseed in with real genetics. i don't think my other girls were effected and i got some wax off the 4-5week old herm so not the end of the world. nice job though keep growin'
