Fastbuds gorilla glue cfl grow

Hi guys,
This is my first thread so apologies if it's in the wrong place.

I am about to do my first indoor grow, inside a wardrobe, I have some gorilla glue auto seeds from fastbuds and I'm wondering if I should grow one or two plants?

The wardrobe dimensions are: 19" x 29" x 50" (31" between top of pot and light at it's highest setting).
I am growing in 10l pots with biobizz lightmix, biobizz grow and biobizz bloom. I also have hard water where I am so CAL-MAG shouldn't be an issue.
I have a 300w CFL and an extraction fan installed, reflective foil on the walls and a small clip fan should I need it. I figured however that this would be unnecessary (and may even cause wind burn) as the extraction fan already creates quite a lot of air flow within such a small space and I could simply turn the pots to mimic a change of wind direction. What do you guys think?

I plan to do a fair amount of LST/defoliation and was even considering topping and mainlining from the 3rd node as I've seen others have great success with these training methods using fastbuds genetics.

Any advice you guys have is massively appreciated.
I will post pictures of the cabinet later and continue to document the grow in this thread.

I think you could fit 2 autos in that space. I am currently doing 2x2, and i consider doing 2 autos for the next run.
Im running G14 from fastbuds, and topped it after 2 weeks i think. Its doing really well.
Anyways. Do you have anything to control Temp/hum?
For future runs (if you have the money) i would upgrade your light to LED. CFL gives very bad lighting spectrum for the plants, and yields/watt is very low. Go for quantum board LED’s. I think you should keep your clip-on fan in there.

Hi thanks for the reply.
I ended up going with two plants and 6 days after germination, they're doing quite nicely. One sprouted a day ahead of the other and has stretched to the top of the pot, I plan to top the pot up with soil tomorrow night and maybe remove the humidity dome/lower lights. The other I will do a day or two later.

The reason I went with CFL was because of the low heat they emit. My apartment block is a very warm building and the room regularly sits at around 25°c with the intake (normally) a degree or so cooler. To combat this I plan on getting an air conditioning unit however in the meantime, I have been experimenting and have crafted somewhat of an air cooled light hood by attaching the extractor fan to it and taping a clear plastic bottle to it which has brought the cabinet temps down to around 26-27°c. I can also further drop the temperature another degree or two by placing a 2l bottle of ice infront of the intake fan which lasts around 6hrs during the hottest hours of the day, slightly longer at other times.

I have uploaded pictures as promised.

I'm going to guess that is a 150-200 watt? Here's the deal. You can grow with CFLs, but if you use that you won't get much. The idea with CFLs is they only penetrate so far. They nees to be 2-4" at all times from the plant. 1 big light can't do that. 200 watts is recommended per plant and using many smaller bulbs all around the plant. 23-26 watts are good. You can make a rig with 2 bulb splitters that screw into a adapter to plug in. If you use this big light it won't do much. Having 8 or more smaller bulbs per plant will suck to keep moving, but it's the better way. Good luck.

Thanks for your advice and no, it's a 300w dual spectrum. I couldn't find the adaptors you speak of and I already have this bulb now so I'll probably just run with it this time. I may add a few additional smaller CFL's later but I've seen others have grea success with CFL light hoods and training rather than dangling multiple bulbs around the plant and I'm less concerned with yield than I am learning the ropes anyway

You're right. If you can train a full flat canopy you will be fine, but they still only penetrate aboit 6" down before losing intensity. I didn't figure you had enough experience in training since you are growing with CFLs. Don't be offended, I'm just helping. I would check out the Spider Farmer QBs on Amazon. The 1000 watt is for a 2x2 and should be cheap and would rock your plants. Just my opinion, but why waste time and money to not put in some effort and get semi decent equipment? No need to spend 1,000s of dollars.

No offence taken, I nearly went with mars hydro LED's but was concerned that they'd produce more heat than the CFL and tbh, now that we all face the current lockdown situation and not being able to work, I'm kinda glad I went with the cheaper option. I do have some (limited) experience with training by helping friends with grows but I've never grown/trained a plant from seed to harvest. However, I figured everyone must start somewhere and with the help of a trusted friend and the forum community, I'll be off to a half decent start.

Hi guys, quick update on the plants.

They're on day 17 from start of germination/day 14/15 from sprouting and are doing well, apart from an error on my behalf in which I accidentally knocked one of the second leaves off one of the seedlings when topping the soil up which stunted her growth but she's came back nicely, albeit, considerably smaller than the other, she was the smaller plant anyway though.

The leaves on both plants are starting to yellow around the edges. My immediate thought was nutrient burn as they are still quite young but I've been advised this shouldn't be the case as they are in Lightmix with quite a bit of added perlite so is probably a nitrogen deficiency. I thought I would consult with the forum too before I start adding nutrients. What do you guys think?

Hey badger, are you feeding them anything or does biobizzs light mix have nutrients in it? It's coco right?

It's an organic soil mix, mainly consisting of: coco, mosses, organic matter such as worm casts, bat guano etc. perlite, and a small amount (about half the amount as in all mix) of biobizz premix. It should feed for the first few weeks and as it's the lightmix, I've heard even autos usually don't get nutrient burn, plus I've added extra perlite...

Definitely looks like something's going on, are you PHing ?

BioBizz Lightmix is contains a pH buffer and their full nutrient line is pH perfect so there should be no need to pH at all during the grow

Not sure then, maybe your right and they just needs some food? If your worried about giving them too much just start with 1/4 or even 1/8 strength.

I think so. I gave them a half dose earlier today and will post an update on how they respond in a couple days.

Hi guys, sorry for the delayed update but I have been extremely busy with other things lately.

As for an update on the nutrient situation, the plants both responded well to the feeding and have since had their dosages increased. As of yesterday, I have started to add the Bio Bloom as I came back after a few days away and they have entered preflower.

I have topped and began training the larger plant however one of the tops has decided to grow extremely slowly so I may cut it off if it doesn't catch up soon and when I got back yesterday, she had grown quite considerably so I accidentally snapped one of the main stems nearly off trying to train her (I knew it was risky but decided to take the chance as I had already began training the plant and didn't want to change method this late in). I have propped the stem up with a wire support and wrapped a small amount of duct tape around it, hopefully she'll recover in a few days. This also meant I had to change the shape of the rest of the stems so that I have an even canopy.

As for the smaller plant who's second leaf I knocked off in the beginning. She also had an issue where one fan leaf on each node was missing fingers but this doesn't seem to be effecting growth anymore. I have used LST with her as I didn't want to top such a small plant and she is still way smaller than the other!

I will add pictures of after the initial feed and now.

How’s it going?
