Seeking Advice on Maximizing Yield in Indoor Grow Setup

[KelvinG]

Hello Everyone,

Though I’ve learnt a lot from a variety of sources and am relatively new to indoor gardening, I’m hoping for some particular guidance to improve my setup. I want to make the most of my little indoor grow space and increase my production as much as possible.

Here’s a quick rundown of my configuration:

• Size of Grow Area: 4 x 4 feet
• Lighting: Full-spectrum 600W LED lighting
• Growing media: a combination of perlite and coco coir
• A well-balanced mixture of nutrients (for both the vegetative and blooming periods)
• Ventilation: oscillating fan and inline fan with carbon filter.
  I’ve read that preserving ideal circumstances is essential for optimising yield, so I’m concentrating on a few important areas:

Light Distance and Intensity: What is the best distance to keep the lights from the canopy to avoid light stress while maximizing coverage and intensity?
Nutrient Feeding Schedule: How often should I be feeding my plants, and are there any specific nutrient formulations or additives that can significantly boost yield?
Environmental Control: What are the ideal temperature and humidity ranges for each growth stage? I’m using a basic hygrometer and thermometer but would appreciate any tips on maintaining consistent conditions.
Training Techniques: Are there any training techniques or pruning methods that can help improve yields in a 4×4 space?

Any insights or personal experiences with similar setups would be greatly appreciated. I’m eager to learn and improve my indoor growing skills.

Thank you in advance for your help!

I’ve replied the best I can but we need more info to give you better answers.

Question: What is the best distance to keep the lights from the canopy to avoid light stress while maximizing coverage and intensity?
Response: Which brand and model LED grow light are you using? Once we know that, we can give you an idea of light distance.

Question: How often should I be feeding my plants, and are there any specific nutrient formulations or additives that can significantly boost yield?
Response: Do you have a pH meter and a TDS tester? What nutrient lineup are you using? Frequency of feeding will depend on which nutrients you use.

Question: What are the ideal temperature and humidity ranges for each growth stage?
Response: Check out these VPD charts which show you for the stage of growth you’re in, what the relative humidity should be for the temperature you’re running. I personally like to run 80-82°F throughout the whole grow cycle, but some growers run higher or lower temps than that.

Question: Are there any training techniques or pruning methods that can help improve yields in a 4×4 space?
Response: Look into low-stress training, topping, and super cropping. Also look into lollipopping and defoliation.
