What is your biggest question about growing cannabis?

[MmmHmmml3]

I have a question about topping and fim. I have been reading a lot on this when trying to decide what method to go with on the autos.

What is the difference between just cutting off the fan leaves so all the lower growth gets light and now you have more colas? Can you get the same result with this and if so, is there any benefit to just cutting the early fan leaves? I imagine less stress and maybe thats the whole point. This would be somewhere in the middle between fim and topping in regards to stress level on the plant.

After I fim'd the plant, it seemed about the same as just cutting the fan leaves off blocking the light. It seems like with fim we are just trimming the fan leaves to let light hit further down.

The plant below was from a lavender photo seed that made two plants (split them right away). The other is normal to large for 3 weeks old and this one is tiny. Fan leaves were blocking this new growth from getting light. Since this is an extra plant I figured f it, let's try this and I cut the fan leaves off in hopes that all 4 sections with new leaves will keep growing.

Here is the past information about all plants

Thank you for your encouragement; hopefully there will be good results; I will continue to describe all the plants on other channels; thank you again!

Mingzhu, They look really wonderful!! It's good to train a Sativa because otherwise, they can get very tall, too tall! You are a very fast learner, very good at absorbing the information you have read from Nebula, and your plants show that you have taken excellent care of them.

[Retodd]

They’re healthy. Sativa is a scrawny plant as is. I’ve lollipoped over the years, fluxed, super cropped, and let grow naturally. I’ve only grown sativa a couple times, but have never cropped it. Looks like you’re doing everything right, so just be patient. Good luck

Additional explanation: I am using a coconut perlite 5 gallon air tank; 4@315LEC+2@630LEC+1@300 watt LED; GH3 combination + calcium magnesium + seaweed + silicone... indoor 3.5@4@3 (high) (Unit: m) I like to plant, like to study plants; so I am not afraid of failure! No matter what my results are, I would like to thank the great forum and the nebula! Because here, because you have aroused my desire to research and plant this magical plant! Thank God; from the current situation, the girls seem to be very good! Add some photos

[mingzhu]

I was the first to try to grow a Sativa-led strain; I read a lot of articles about the strain and read the Nebula article and introduction; selected some seeds; in the training I used the main lining of the nebula and related LST technology; but I don't know if these trainings will suit these strains! I made a bold and adventurous attempt! (This includes more defoliation treatment) I want to know if these buds will produce big colas; they have grown for 49 days, flipped 12/12 for a week! At present, all plants have white hair; but I want to know; I have done a lot of training and defoliation before flipping; whether they hurt them! Thanks for all the comments! Thank you!

My indoor grow is a 2x4x5 tent and I mainly use it for veg. I’ve grown widows in it last year and blue cheese during the winter, but had a screw up on both grows...lol. I’m going to tag Spidermite and he’ll be able to tell you how well his do as far as mass weight

Retodd - What size harvest or g per w have you been getting with the 450w light? Looking back I should have just bought that. Based on initially plans a larger hanging system would not be ideal, but now it's not an issue. I think I might grab the 300w version of the Viapsectra. It looks like it might pair great with the 54w cxb-3590 3500k I already have. It gives some more red and blue. Mounting might be odd though unless I put them across from each other at a very light angle towards the other light.

[Retodd]

Rule of thumb, you get what you pay for. Me and a bunch of other growers all use the viparspectra 450w. It runs around $115 on eBay.

[MmmHmmml3]

Are these lights even worth buying? Just looking for some sort of cheap supplemental lighting to pair with the main light. I kind of like this 20pc 2.4w cob led, maybe it can be put onto some sort of movable standing device that can be put really close to the plants. It doesn't seem ideal for putting on the walls because it probably isn't strong enough unless it's close to the plant.

Maybe something like this and mount it above the other light or on the side. I would have to remove the outer part that looks like it would dim it some. The color seems nice 2800k-3500k and it's 3 COB LEDs for 22$. Perhaps this could make a decent base and then mod it a bit.

A couple other cheap lights like this as well, but not sure if these are all so bad it's not worth the small cost.

If none of these are good the other option is slowly buy and build some sort of custom light, but ideally I do this and also get a cheap supplemental light for right now.

Can anyone recommend good places to order indoor growing supplies in the U.S? I am not so much looking for a list of supplies that would be good, but I want to browse various things. The issue now is if I want an item I just search it on google and find this item. It would be nice to find a well known growing supply company where I can browse various options.

I am also wondering what are some must have insecticides to make sure I have 0 issues with bugs before my plants get larger. They have 6 leaves right now and I only see a small fly or mosquito here and there which I kill with my hands. I want to get a couple of the best items right now that will prevent any possible issue with bugs.
