I titled it third grow, it's actually my fourth as I mentioned in the OP. Bit of a stoner moment there haha.

I love thc bomb. Always a great grow and very affordable. Hash bomb was good also, very fast finisher with great resin production. Right now I've got 3 thc bomb phenos about ready to chop this weekend and my main breeding male is the indica pheno. Great choice on the beans.

Really enjoyed your previous journals. Very keen to see how this one pans out 👍🏻

I swear I'm getting worse and worse Ozbud I got down to the Ballast before it sank in the they were not all seeds I mean I had a hell of a time figuring out what gorilla glue 2x4 was there is GG and GG4 just figured it was a new strain lol

I love growing thc bomb big fat kolas can feed it as much as you want loves the nutes from one of my Autos last year I got about 10 ounces from it, that was outside in full sun

 

[OzBud]

Did you get any nice purples like in some of the photos of THC Bomb online? I'd like a nice bit of purple but I've got some LSD 25 to run later in the year after some Kings Kush CBD to try get some nice purple bud

 

[oldjarhead100]

no purples it was outside in the garden ,I'm pretty sure if you can get a 20 degree swing in your night time temp ranges you will get purple

 

[OzBud]

Here's a bit of a look until I get time to come back and fill you in on what's been happening with this grow so far.

The 3 girls Day 9

 

[oldjarhead100]

good morning OZbud what is that sitting on the pots ,for 9 days they are looking great

 

[Tika]

Perfect little creatures!!!!

 

[OzBud]

hello oldjarhead100 that's just the cardboard box the light globe comes in. I hide the thermometer in there when there's not much plant foliage so it gives an ambient temp reading, not affected by the radiant heat of the light

 

[OzBud]

Ok, well I've got a day off today and it's pouring with rain so I can't get out and do anything in the garden so I'll look at the indoor garden instead and try and fill in what's been happening so far in the grow.

SET UP & WK1

I set up the tent on March 4th, gave it a wipe over with bleach (I did the same at the end of last grow but I like a clean environment) and soaked 5 seeds (15 months old and just kept in a bag in a box in the cupboard) in water for 6 hours. After 6 hours 3 had sunk to the bottom so I planted them in jiffys and put them in a dome under a fluro light. It was too warm, even at night for a heat mat so I just used the ambient heat and the heat from the light sitting right on top of the dome to keep them warm and temps in the dome stayed pretty stable at 22-25C.

I was giving each jiffy 2ml of water once a day. After 2.5 days the first seedling emerged. Another one at 3 days and a third at 3.5 days. After a week two still hadn't emerged so they were thrown away.

on March 8 I rehydrated my Nutrifield Coco brick with 25L of pH 6 water plus 5ml/Gal of CALiMAGic. I then transplanted my seedlings into 3.5gal pots and watered them in with 1L each of 50% strength Week 1 seedling mix.

Two days later they each got 2L of 50% strength week 1 seedling mix, two days later 2L each of 60% strength Week 1 seedling mix & then another two days after that got 2L each of 70% strength Week 1 seedling mix.

 

[OzBud]

When watering in the seedlings I also added a spoon of Great White to the mix.
With the last Week 1 feed they also got 10ml of Terpinator (I forgot I had some in the cupboard that I scored for free at an expo last year)

WK 2

Day 8 2.5L each of 50% Strength Week 2 Early Growth Mix
Day 9 2.5L each of 60% Strength Week 2 Early Growth Mix
Day 10 1.5L each of 70% Strength Week 2 Early Growth Mix
Day 11 1.5 L each of 80% strength Week 2 early Growth Mix
Day 12 1.5L each of 85% Strength Week 2 early growth mix
Day 13 2L each of 85% Strength Week 2 early growth Mix
Day 14 2L each of 50% Strength Week 2 early growth Mix (drain EC last watering was slightly higher than EC going in so I reduced the nute strength) plus some Great White.

All week 2 waterings had 5-10ml of Terpinator added

 

[OzBud]

WK 3 so far

Day 15 2L each of 50% strength week 3 late growth mix
Day 16 2L each of 50% strength week 3 late growth mix

All week 3 waterings will receive 10ml of terpinator as well

Gooooood to see you on the job😊 Nice rich diet there! Looking into Great White....Eager for your pics.

 

[OzBud]

OK so this grow I decided to keep my records electronically in Excel spreadsheets. Every day I input the amount of nutes etc I've used and it adds it up for me and calculates the cost for the grow plus other cost data that I've input.

I'm also recording min/max temp & humidity, pH in/out, EC in/out, water in/out/drain% & plant height and I've added graphs that pull the data I put in the spreadsheet so I can easily visually track things too. Way more complicated than the average grower needs but I do something similar with all my data at work and I enjoy making spreadsheets so I thought I'd try it this way.

I've also updated my nute calculator spreadsheet I made last grow to include Terpinator, Great White Mychorrizae. I've also changed the CALiMAGic to full strength all grow rather than just to flower before backing off to the normal recommended rate from the GH feed charts.

 

[Tika]

I am seriously glad I don't know what it costs me and seriously glad I no longer remember Excel and SERIOUSLY glad you take the time for your spread sheets to share. A serious gift and thank you....Still waiting to see babies
